B1102

DTC B1102

CIRCUIT DESCRIPTION
When the ignition switch is turned to ON, the sensing and diagnostic module (SDM) will perform a turn-on test to diagnose critical malfunctions within the SDM itself.

These test ignition and deployment loop voltages are measured to ensure that they are within their normal voltage ranges. The SDM monitors the voltages at the driver low and the passenger low to detect shorts to ground or voltage in the deploy loops.

DTC DESCRIPTOR
This diagnostic procedure supports the following DTC:
DTC B1102 Battery Voltage Low

CONDITIONS FOR RUNNING THE DTC
