B1395

DTC B1395

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 deployment loops.

The SDM inspects the air bag wiring by letting the perpetual current flow through the internal circuit and verify the resistance.

If the scan tool displays DTC B1395, connect the wrong high or low wiring correctly or replace the air bag wiring.
