B1415

DTC B1415

Circuit Description

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

Upon passing 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.

Conditions for Setting the DTC

The sensor for communication between the SDM and the passenger side air bag sensor is not identified.
