Malfunction Lamp / Indicator: Testing and Inspection
The diagnosis found here addresses an inoperative lamp condition. If the airbag indicator lamp stays on with the ignition switch in the On position, or
comes on while driving, refer to Air Bag Systems for diagnosis. If no airbag system problem is found, the following procedure will help locate a short or
open in the airbag warning lamp circuit.
1. Disconnect and isolate the battery negative cable. Remove the instrument cluster bezel as described. Unplug the message center wire harness
connector.
2. Connect the battery negative cable. Check for battery voltage at the airbag system warning lamp driver circuit cavity of the message center wire
harness connector within six seconds after turning the ignition switch to the On position. If OK, replace the faulty bulb. If not OK, go to Step 3.
3. Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable. Unplug the 13-way Airbag Control Module (ACM)
wire harness connector. Check for continuity between the airbag system warning lamp driver circuit cavities of the message center wire harness
connector and the ACM wire harness connector. There should be continuity. If OK, refer to Air Bag Systems for diagnosis of the ACM. If not OK,
repair the open circuit as required.
