B1310:11


Refer to Wiring Diagrams Cell 12 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 large number of shorts to ground or excessive 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, video camera, and HUD module being inoperative.
