  DTC Fault Trigger Conditions


DTC Description Fault Trigger Conditions
B117C:16 Rear Power Window Up: Circuit Voltage Below Threshold This DTC sets when the RDM senses the RH rear window regulator motor circuit voltage is too low.
B118A:29 Rear Window Position Sensor: Signal Invalid This DTC sets when the RDM detects 16 missing pulses on one of the Hall-effect sensor circuits during window movement. When this DTC is present, the rear window only operates in short steps.
B12C6:71 Rear Window Lifter Motor Up Relay: Actuator Stuck This DTC sets when the RDM detects the UP relay (integral to the RDM ) is stuck or a short to voltage is present in the UP window motor circuit. When this DTC is present, the rear window does not operate.
B12C7:71 Rear Window Lifter Motor Down Relay: Actuator Stuck This DTC sets when the RDM detects the DOWN relay (integral to the RDM ) is stuck or a short to voltage is present in the DOWN window motor circuit. When this DTC is present, the rear window does not operate.
B12E9:24 Rear Window Local Up/Down Switch: Signal Stuck High This DTC sets when the RDM detects the window control switch is stuck in the UP or DOWN position or a short to ground is present on the input circuit for greater than 10 seconds.

No The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.


Component Test- Grid Wire Test

  1. Using a bright lamp in the vehicle, inspect the grid wire from the exterior. A broken grid wire appears as a brown spot.
  1. Run the engine at idle. Activate the rear window defrost switch. The indicator light should come on.
  1. Working in the vehicle with a voltmeter, contact the broad red-brown stripes of the rear glass window (positive lead to B+ side and the negative lead to ground side). The meter should read 10-13 volts. A lower voltage reading indicates a loose ground connection.
  1. Contact a good ground point with the negative lead of the meter. The voltage reading should not change.
  1. With the negative lead of the meter grounded, touch each grid line of the heated rear window glass at its midpoint with the positive lead. A reading of approximately 6 volts indicates the line is good. A reading of 0 volt indicates the line is broken between the midpoint and the B+ side of the grid line. A reading of 12 volts indicates the circuit is broken between the midpoint of the grid line and ground.
  1. Pinpointing the exact position of the break can be accomplished (if the voltmeter reads 0 volt when the midpoint of the grid line is touched with the positive lead of the voltmeter) by moving the positive lead of the voltmeter toward the B+ side of the grid line and touching the grid line until the voltmeter reads 12 volts. If the voltmeter reads 12 volts when the midpoint of the grid line is touched with the positive lead of the voltmeter, simply move the positive lead of the voltmeter toward the ground connection of the grid line and touch the grid line until the voltmeter reads 0 volt.
