Table C Air Bag Warning Lamp Does Not Come On

When measurements are requested in this table, use J 39200 DMM with the correct terminal adapter from J 35616-A Connector Test Adapter Kit. When a check for proper connection is requested, refer to Intermittents and Poor Connections in Diagrams. When a wire, connector, or terminal repair is requested, use J 38125-A Terminal Repair Kit and refer to Wiring Repair.

CIRCUIT DESCRIPTION

When the ignition switch is first turned to ON, the IG-COIL METER Fuse applies battery voltage to the AIR BAG warning lamp that is connected to AIR BAG INDICATOR, terminal 7. The AIR BAG Fuse applies battery voltage to the IGNITION 1 input, terminal 8. The inflatable restraint Sensing and Diagnostic Module (SDM) responds by flashing the AIR BAG warning lamp seven times.

TABLE TEST DESCRIPTION

Numbers below refer to step numbers on the diagnostic table.
2. This test determines whether the malfunction is in the inflatable restraint Sensing and Diagnostic Module (SDM) circuitry or in the Instrument Panel Cluster (IPC) power feed circuitry.
3. This test determines whether voltage is present in the warning lamp circuit.
4. This test isolates CKT Or and checks for a short in CKT Or to B+.
6. This test determines if the malfunction is in the IPC connector.
8. This test determines if the open is due to a bad bulb.
10. This test isolates an open in the warning lamp circuitry.
13. This test checks whether power is available to the IPC power feed circuit.
14. This test checks for a short from the IPC power feed circuit to ground.
15. This test determines whether the short-to-ground is due to a short in the wiring or internal to the IPC.
19. This test determines if the malfunction is in the IPC connector.
21. This test determines whether the malfunction is due to an open power feed circuit from the 10-COIL METER Fuse.
