AIR BAG Indicator Does Not Come ON

AIR BAG INDICATOR DOES NOT COME ON

CIRCUIT DESCRIPTION
The ignition switch supplies battery voltage to the AIR BAG indicator using the AM2 fuse. The AIR BAG indicator is connected to the AIR BAG indicator control circuit of the SDM. When the ignition switch is first turned to the ON position, the SDM responds by illuminating the AIR BAG indicator for approximately six seconds while performing diagnostic tests on the SIR system.

DIAGNOSTIC AIDS
Thoroughly inspect the wiring and the connectors. An incomplete inspection of the wiring and the connectors may result in a misdiagnosis, causing a part replacement with the reappearance of the malfunction.

The following are possible causes of the malfunction:
- An open or high resistance in the AIR BAG indicator control circuit
- An open AIR BAG indicator bulb
- An internal SDM malfunction

If an intermittent malfunction exists, refer to Diagnostic Aids for Circuit Testing and Wiring Repair Procedures.

TEST DESCRIPTION
