DTC 033

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.

If driver side air bag inflation was caused by side impact, the SDM maintains warning lamp ON and the entire air bag system should be inspected, including pretensioners. The side air bag sensor and wiring should be replaced. If the driver side air bag inflation by side impact counts over 5, the SDM should also be replaced.

Conditions for Setting the DTC

The history of the air bag inflation or belt pretensioner explosion is in the SDM.
