Test Description

The number below refers to the step number on the diagnostic table.

3: This step tests for proper operation of the air bag indicator control circuitry. With the SDM connector disconnected, the shorting bar connects the Air Bag Indicator Control circuit to ground and should illuminate the indicator.

Air Bag Indicator Does Not Come ON

Step	Action	Yes	No
Schematic Reference: SIR Schematics
1	Did you perform the Diagnostic System Check - SIR?	Go to Step 2	Go to Diagnostic System Check - SIR
2	Do any of the other instrument cluster indicators or gages function?	Go to Step 3	Go to Symptoms - Instrument Panel, Gages and Console in Instrument Panel, Gages, and Console
3	Turn OFF the ignition. Disconnect the sensing and diagnostic module (SDM) connector. Turn ON the ignition, with the engine OFF. Does the AIR BAG indicator come ON?	Go to Step 5	Go to Step 4
4	Turn OFF the ignition. Inspect the SDM connector for the following conditions: Corrosion Damaged terminals Poor connections/terminal tension Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 7	Go to Step 6
5	Replace the SDM. Refer to Inflatable Restraint Sensing and Diagnostic Module Replacement . Did you complete the replacement?	Go to Step 7	-
6	Repair the open or high resistance in the air bag indicator control circuit. Refer to Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 7	-
7	Operate the system in order to verify the repair. Did you correct the condition?	System OK	Go to Step 2
