Refer to Wiring Diagrams Cell 40 for schematic and connector information.

Normal Operation and Fault Conditions

During an auto-start-stop event, the PCM sends a voltage signal to the Direct Current/Direct Current (DC/DC) converter control module through the boost enable circuit. If the PCM boost enable circuit becomes shorted to ground, or is low for more than 60 seconds DTC P0A12:11 sets and the Direct Current/Direct Current (DC/DC) converter control module will not boost. If the enable circuit becomes open, the Direct Current/Direct Current (DC/DC) converter control module will not receive a re-crank signal from the PCM and the Direct Current/Direct Current (DC/DC) converter control module will not boost. Any systems powered through the Direct Current/Direct Current (DC/DC) converter control module may restart during an auto-start-stop event. For more information on the auto-start-stop system,

B1310:11


Refer to Wiring Diagrams Cell 40 for schematic and connector information.

Normal Operation and Fault Conditions

The Direct Current/Direct Current (DC/DC) converter control module measures the current draw on the run/start switched output circuit. If the Direct Current/Direct Current (DC/DC) converter control module detects a short to ground or if the current draw exceeds 8 amps the DTC B1310:11 sets and the switching transistor is disabled for the current ignition cycle. A excessive number of shorts to ground or current draw events will set DTC U1000:00 and the switching transistor is disabled until it is reset using a diagnostic scan tool. Presence of this DTC may result in the blind spot detection and video camera being inoperative.
