DTC B1484

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.

Conditions for Setting the DTC

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

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