Air Bag Indicator Does Not Come ON

AIR BAG INDICATOR DOES NOT COME ON

CIRCUIT DESCRIPTION
The ignition switch supplies ignition 1 voltage to the inflatable restraint sensing and diagnostic module (SDM). The ignition switch also supplies battery voltage to the AIR BAG indicator using the F4 fuse. The AIR BAG indicator is connected to the AIR BAG indicator output of the SDM. When the ignition switch is first turned to the ON position, the SDM responds by flashing the AIR BAG indicator 7 times.

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 a reappearance of the malfunction. If an intermittent malfunction exists, refer to Testing for Intermittent Conditions and Poor Connections.

TEST DESCRIPTION

Step 1 - Step 7:

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.
