Normal Operation and Fault Conditions

The RCM continuously monitors the driver airbag stage 1 circuits for the following faults:

  • Resistance out of range
  • Unexpected voltage
  • Short to ground
  • Faulted driver airbag

If a fault is detected, the RCM stores DTC B0001:11, B0001:12, B0001:13 or B0001:1A in memory and sends a message to the IPC to illuminate the airbag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC . As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:

  • Wiring
  • Connections
  • Clockspring
  • Driver airbag
  • RCM
  • 1 - May set DTC
  • 2 - Desired range

PINPOINT TEST B: B0002:11, B0002:12, B0002:13, B0002:1A

Refer to Wiring Diagrams Cell 46 for schematic and connector information.

Normal Operation and Fault Conditions

The RCM continuously monitors the driver airbag stage 2 circuits for the following faults:

  • Resistance out of range
  • Unexpected voltage
  • Short to ground
  • Faulted driver airbag

If a fault is detected, the RCM stores DTC B0002:11, B0002:12, B0002:13 or B0002:1A in memory and sends a message to the IPC to illuminate the airbag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC . As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:

  • Wiring
  • Clockspring
  • Driver airbag
  • Connections
  • RCM
  • 1 - May set DTC
  • 2 - Desired range

PINPOINT TEST C: B0004:11, B0004:12, B0004:13, B0004:1A

Refer to Wiring Diagrams Cell 46 for schematic and connector information.

Normal Operation and Fault Conditions

The RCM continuously monitors the driver knee airbag circuits for the following faults:

  • Resistance out of range
  • Unexpected voltage
  • Short to ground
  • Faulted driver knee airbag

If a fault is detected, the RCM stores DTC B0004:11, B0004:12, B0004:13 or B0004:1A in memory and sends a message to the IPC to illuminate the airbag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC . As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:

  • Wiring
  • Connections
  • Driver knee airbag
  • RCM
  • 1 - May set DTC
  • 2 - Desired range

PINPOINT TEST E: B0011:11, B0011:12, B0011:13, B0011:1A

Refer to Wiring Diagrams Cell 46 for schematic and connector information.

Normal Operation and Fault Conditions

The RCM continuously monitors the passenger airbag stage 2 circuits for the following faults:

  • Resistance out of range
  • Unexpected voltage
  • Short to ground
  • Faulted passenger airbag

If a fault is detected, the RCM stores DTC B0011:11, B0011:12, B0011:13 or B0011:1A in memory and sends a message to the IPC to illuminate the airbag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC . As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:

  • Wiring
  • Connections
  • Passenger airbag
  • RCM
  • 1 - May set DTC
  • 2 - Desired range

PINPOINT TEST F: B0013:11, B0013:12, B0013:13, B0013:1A

Refer to Wiring Diagrams Cell 46 for schematic and connector information.

Normal Operation and Fault Conditions

The RCM continuously monitors the passenger knee airbag circuits for the following faults:

  • Resistance out of range
  • Unexpected voltage
  • Short to ground
  • Faulted passenger knee airbag

If a fault is detected, the RCM stores DTC B0013:11, B0013:12, B0013:13 or B0013:1A in memory and sends a message to the IPC to illuminate the airbag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC . As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:

  • Wiring
  • Connections
  • Passenger knee airbag
  • RCM
  • 1 - May set DTC
  • 2 - Desired range

DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition
RCM B0013:11 Passenger Knee Bolster Deployment Control: Circuit Short To Ground A fault is indicated when the RCM senses a short to ground on either passenger knee airbag circuit for more than 6 seconds.
RCM B0013:12 Passenger Knee Bolster Deployment Control: Circuit Short To Battery A fault is indicated when the RCM senses a short to voltage on either passenger knee airbag circuit for more than 6 seconds.
RCM B0013:13 Passenger Knee Bolster Deployment Control: Circuit Open A fault is indicated when the RCM measures more than the desired resistance between the passenger knee airbag circuits for more than 6 seconds.
RCM B0013:1A Passenger Knee Bolster Deployment Control: Circuit Resistance Below Threshold A fault is indicated when the RCM measures less than the desired resistance between the passenger knee airbag circuits for more than 6 seconds.

PINPOINT TEST I: B0070:11, B0070:12, B0070:13, B0070:1A

Refer to Wiring Diagrams Cell 46 for schematic and connector information.

Normal Operation and Fault Conditions

The RCM continuously monitors the driver Seatbelt anchor pretensioner circuits for the following faults:

  • Resistance out of range
  • Unexpected voltage
  • Short to ground
  • Faulted driver seatbelt anchor pretensioner

If a fault is detected, the RCM stores DTC B0070:11, B0070:12, B0070:13 or B0070:1A in memory and sends a message to the IPC to illuminate the airbag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC . As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:

  • Wiring
  • Connections
  • Driver Seatbelt anchor pretensioner
  • RCM
  • 1 - May set DTC
  • 2 - Desired range

PINPOINT TEST K: B007E:11, B007E:12, B007E:13, B007E:1A

Refer to Wiring Diagrams Cell 46 for schematic and connector information.

Normal Operation and Fault Conditions

The RCM continuously monitors the driver seatbelt retractor pretensioner circuits for the following faults:

  • Resistance out of range
  • Unexpected voltage
  • Short to ground
  • Faulted driver seatbelt retractor pretensioner

If a fault is detected, the RCM stores DTC B007E:11, B007E:12, B007E:13 or B007E:1A in memory and sends a message to the IPC to illuminate the airbag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC . As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:

  • Wiring
  • Connections
  • Driver seatbelt retractor pretensioner
  • RCM
  • 1 - May set DTC
  • 2 - Desired range

PINPOINT TEST L: B007F:11, B007F:12, B007F:13, B007F:1A

Refer to Wiring Diagrams Cell 46 for schematic and connector information.

Normal Operation and Fault Conditions

The RCM continuously monitors the passenger seatbelt retractor pretensioner circuits for the following faults:

  • Resistance out of range
  • Unexpected voltage
  • Short to ground
  • Faulted passenger seatbelt retractor pretensioner

If a fault is detected, the RCM stores DTC B007F:11, B007F:12, B007F:13 or B007F:1A in memory and sends a message to the IPC to illuminate the airbag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC . As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:

  • Wiring
  • Connections
  • Passenger seatbelt retractor pretensioner
  • RCM
  • 1 - May set DTC
  • 2 - Desired range

DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition
RCM B007F:11 Passenger Seatbelt Pretensioner 'C' Deployment Control: Circuit Short To Ground A fault is indicated when the RCM senses a short to ground on either passenger seatbelt retractor pretensioner circuit for approximately 6 seconds.
RCM B007F:12 Passenger Seatbelt Pretensioner 'C' Deployment Control: Circuit Short To Battery A fault is indicated when the RCM senses a short to voltage on either passenger seatbelt retractor pretensioner circuit for approximately 6 seconds.
RCM B007F:13 Passenger Seatbelt Pretensioner 'C' Deployment Control: Circuit Open A fault is indicated when the RCM measures more than the desired resistance range between passenger seatbelt retractor pretensioner circuits for approximately 6 seconds.
RCM B007F:1A Passenger Seatbelt Pretensioner 'C' Deployment Control: Circuit Resistance Below Threshold A fault is indicated when the RCM measures less than the desired resistance range between passenger seatbelt retractor pretensioner circuits for approximately 6 seconds.

PINPOINT TEST M: B0082:11, B0082:12, B0082:13, B0082:1A

Refer to Wiring Diagrams Cell 46 for schematic and connector information.

Normal Operation and Fault Conditions

The RCM continuously monitors the passenger seatbelt load limiter circuits for the following faults:

  • Resistance out of range
  • Unexpected voltage
  • Short to ground
  • Faulted passenger seatbelt load limiter

If a fault is detected, the RCM stores DTC B0082:11, B0082:12, B0082:13 or B0082:1A in memory and sends a message to the IPC to illuminate the airbag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC . As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:

  • Wiring
  • Connections
  • Passenger seatbelt load limiter
  • RCM
  • 1 - May set DTC
  • 2 - Desired range

DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition
RCM B0082:11 Passenger Seatbelt Load Limiter Deployment Control: Circuit Short To Ground A fault is indicated when the RCM senses a short to ground on either passenger seatbelt load limiter circuit for more than 6 seconds.
RCM B0082:12 Passenger Seatbelt Load Limiter Deployment Control: Circuit Short To Battery A fault is indicated when the RCM senses a short to voltage on either passenger seatbelt load limiter circuit for more than 6 seconds.
RCM B0082:13 Passenger Seatbelt Load Limiter Deployment Control: Circuit Open A fault is indicated when the RCM measures more than the desired resistance between the passenger seatbelt load limiter circuits for more than 6 seconds.
RCM B0082:1A Passenger Seatbelt Load Limiter Deployment Control: Circuit Resistance Below Threshold A fault is indicated when the RCM measures less than the desired resistance between the passenger seatbelt load limiter circuits for more than 6 seconds.

PINPOINT TEST T: B11CF:11, B11CF:12, B11CF:13, B11CF:1A

Refer to Wiring Diagrams Cell 46 for schematic and connector information.

Normal Operation and Fault Conditions

The RCM continuously monitors the passenger airbag adaptive canister vent circuits for the following faults:

  • Resistance out of range
  • Unexpected voltage
  • Short to ground
  • Faulted passenger airbag adaptive canister vent

If a fault is detected, the RCM stores DTC B11CF:11, B11CF:12, B11CF:13 or B11CF:1A in memory and sends a message to the IPC to illuminate the airbag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC . As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:

  • Wiring
  • Connections
  • Passenger airbag adaptive canister vent
  • RCM
  • 1 - May set DTC
  • 2 - Desired range

DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition
RCM B11CF:11 Passenger Frontal Airbag Canister Vent: Circuit Short To Ground A fault is indicated when the RCM senses a short to ground on either passenger airbag adaptive canister vent circuit for more than 6 seconds.
RCM B11CF:12 Passenger Frontal Airbag Canister Vent: Circuit Short To Battery A fault is indicated when the RCM senses a short to voltage on either passenger airbag adaptive canister vent circuit for more than 6 seconds.
RCM B11CF:13 Passenger Frontal Airbag Canister Vent: Circuit Open A fault is indicated when the RCM measures more than the desired resistance between the passenger airbag adaptive canister vent circuits for more than 6 seconds.
RCM B11CF:1A Passenger Frontal Airbag Canister Vent: Circuit Resistance Below Threshold A fault is indicated when the RCM measures less than the desired resistance between the passenger airbag adaptive canister vent circuits for more than 6 seconds.

Refer to Wiring Diagrams Cell 46 for schematic and connector information.

Normal Operation and Fault Conditions

The RCM transmits an event notification signal which communicates crash status and SRS deployment status to the BCM . When the BCM receives an event notification signal which indicates a crash, it initiates fuel cut-off.

The RCM monitors the event notification signal circuit for the following faults:

  • Short to voltage
  • Short to ground
  • Open circuit

If a fault is detected, the RCM stores DTC B11D8:12 or B11D8:14 in memory. The airbag warning indicator does not illuminate if B11D8:12 or B11D8:14 is set.

PINPOINT TEST V: B1404:11, B1404:12, B1404:13, B1404:1A

Refer to Wiring Diagrams Cell 46 for schematic and connector information.

Normal Operation and Fault Conditions

The RCM continuously monitors the driver side airbag circuits for the following faults:

  • Resistance out of range
  • Unexpected voltage
  • Short to ground
  • Faulted driver side airbag

If a fault is detected, the RCM stores DTC B1404:11, B1404:12, B1404:13 or B1404:1A in memory and sends a message to the IPC to illuminate the airbag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC . As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:

  • Wiring
  • Connections
  • Driver side airbag
  • RCM
  • 1 - May set DTC
  • 2 - Desired range

DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition
RCM B1404:11 Driver Side Airbag Deployment Control: Circuit Short To Ground A fault is indicated when the RCM senses a short to ground on either driver side airbag circuit for more than 6 seconds.
RCM B1404:12 Driver Side Airbag Deployment Control: Circuit Short To Battery A fault is indicated when the RCM senses a short to voltage on either driver side airbag circuit for more than 6 seconds.
RCM B1404:13 Driver Side Airbag Deployment Control: Circuit Open A fault is indicated when the RCM measures more than the desired resistance between the driver side airbag circuits for more than 6 seconds.
RCM B1404:1A Driver Side Airbag Deployment Control: Circuit Resistance Below Threshold A fault is indicated when the RCM measures less than the desired resistance between the driver side airbag circuits for more than 6 seconds.

Possible Sources

PINPOINT TEST W: B1405:11, B1405:12, B1405:13, B1405:1A

Refer to Wiring Diagrams Cell 46 for schematic and connector information.

Normal Operation and Fault Conditions

The RCM continuously monitors the driver side air curtain circuits for the following faults:

  • Resistance out of range
  • Unexpected voltage
  • Short to ground
  • Faulted Driver side air curtain

If a fault is detected, the RCM stores DTC B1405:11, B1405:12, B1405:13 or B1405:1A in memory and sends a message to the IPC to illuminate the airbag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC . As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:

  • Wiring
  • Connections
  • Driver side air curtain
  • RCM
  • 1 - May set DTC
  • 2 - Desired range

DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition

PINPOINT TEST X: B1407:11, B1407:12, B1407:13, B1407:1A

Refer to Wiring Diagrams Cell 46 for schematic and connector information.

Normal Operation and Fault Conditions

The RCM continuously monitors the passenger side airbag circuits for the following faults:

  • Resistance out of range
  • Unexpected voltage
  • Short to ground
  • Faulted passenger side airbag

If a fault is detected, the RCM stores DTC B1407:11, B1407:12, B1407:13 or B1407:1A in memory and sends a message to the IPC to illuminate the airbag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC . As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:

  • Wiring
  • Connections
  • Passenger side airbag
  • RCM
  • 1 - May set DTC
  • 2 - Desired range

DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition
RCM B1407:11 Passenger Side Airbag Deployment Control: Circuit Short To Ground A fault is indicated when the RCM senses a short to ground on either passenger side airbag circuit for more than 6 seconds.
RCM B1407:12 Passenger Side Airbag Deployment Control: Circuit Short To Battery A fault is indicated when the RCM senses a short to voltage on either passenger side airbag circuit for more than 6 seconds.
RCM B1407:13 Passenger Side Airbag Deployment Control: Circuit Open A fault is indicated when the RCM measures more than the desired resistance between the passenger side airbag circuits for more than 6 seconds.
RCM B1407:1A Passenger Side Airbag Deployment Control: Circuit Resistance Below Threshold A fault is indicated when the RCM measures less than the desired resistance between the passenger side airbag circuits for more than 6 seconds.

PINPOINT TEST Y: B1408:11, B1408:12, B1408:13, B1408:1A

Refer to Wiring Diagrams Cell 46 for schematic and connector information.

Normal Operation and Fault Conditions

The RCM continuously monitors the passenger side air curtain circuits for the following faults:

  • Resistance out of range
  • Unexpected voltage
  • Short to ground
  • Faulted passenger side air curtain

If a fault is detected, the RCM stores DTC B1408:11, B1408:12, B1408:13 or B1408:1A in memory and sends a message to the IPC to illuminate the airbag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC . As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:

  • Wiring
  • Connections
  • Passenger side air curtain
  • RCM
  • 1 - May set DTC
  • 2 - Desired range

DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition
RCM B1408:11 Passenger Side Curtain Deployment Control 1: Circuit Short To Ground A fault is indicated when the RCM senses a short to ground on either passenger side air curtain circuit for more than 6 seconds.

PINPOINT TEST AB: B1410:11, B1410:12, B1410:13, B1410:1A

Refer to Wiring Diagrams Cell 46 for schematic and connector information.

Normal Operation and Fault Conditions

The RCM continuously monitors the second row driver side rear seatbelt retractor pretensioner circuits for the following faults:

  • Resistance out of range
  • Unexpected voltage
  • Short to ground
  • Faulted second row driver side rear seatbelt retractor pretensioner

If a fault is detected, the RCM stores DTC B1410:11, B1410:12, B1410:13 or B1410:1A in memory and sends a message to the IPC to illuminate the airbag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC . As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:

  • Wiring
  • Connections
  • second row driver side rear seatbelt retractor pretensioner
  • RCM
  • 1 - May set DTC
  • 2 - Desired range

DTC Fault Trigger Conditions

PINPOINT TEST AC: B1412:11, B1412:12, B1412:13, B1412:1A

Refer to Wiring Diagrams Cell 46 for schematic and connector information.

Normal Operation and Fault Conditions

The RCM continuously monitors the second row passenger side rear seatbelt retractor pretensioner circuits for the following faults:

  • Resistance out of range
  • Unexpected voltage
  • Short to ground
  • Faulted second row passenger side rear seatbelt retractor pretensioner

If a fault is detected, the RCM stores DTC B1412:11, B1412:12, B1412:13 or B1412:1A in memory and sends a message to the IPC to illuminate the airbag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC . As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:

  • Wiring
  • Connections
  • second row passenger side rear seatbelt retractor pretensioner
  • RCM
  • 1 - May set DTC
  • 2 - Desired range
