B1483

DTC B1483

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.

If the resistance is in the 2-10 kilo ohms range, the defect may occur, depending on the SDM. The normal resistance is over 10 kilo ohms.

Conditions for Setting the DTC

* The air bag wiring of the 2nd stage driver's high is shorted to ground.

* The air bag wiring of the 2nd stage driver's low is shorted to ground.
