Symptom Related Diagnostic Procedures

The AIRBAG indicator will stay on if the sensing and diagnostic module (SDM) connector is not securely attached to the SDM. There is a shorting bar in the SDM connector which completes the circuit between the indicator lamp circuit and ground. The shorting bar is disengaged when the connector is properly attached.

When the ignition switch is first turned to ON, Ignition 1 voltage is applied to the instrument fuse for the indicator lamp and also to the AIRBAG fuse for the SDM input terminal A1. If Ignition 1 is outside the range of 9 to 16 volts, the AIRBAG indicator will come on and stay on with no DTCs set.

A short to ground between the SDM and the indicator lamp could also cause the AIRBAG indicator to stay on.
