Table C Air Bag Warning Lamp Does Not Come On

Diagnostic Chart:

Wiring Diagram:

CIRCUIT DESCRIPTION
When the ignition switch is first turned to RUN, the GAUGES fuse applies battery voltage to the AIR BAG warning lamp that is connected to INFLATABLE RESTRAINT INDICATOR, terminal.The AIR BAGS fuse applies battery voltage to the IGNITION 1 input, terminal 10. The inflatable restraint control module responds by flashing the AIR BAG warning lamp seven times.

TABLE TEST DESCRIPTION
Number(s) below refer to step number(s) on the diagnostic table.
2. This test determines whether the malfunction is in the inflatable restraint control module circuitry or in the instrument cluster power feed circuitry.
3. This test determines whether voltage is present in the warning lamp circuit.
4. This test isolates CKT 358 and checks for a short in CKT 358 to B+.
6. This test determines if the malfunction is in the instrument cluster 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 instrument cluster power feed circuit.
14. This test checks for a short from the instrument cluster 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 instrument cluster.
19. This test determines if the malfunction is in the instrument cluster connector.
21. This test determines whether the malfunction is due to an open power feed circuit from the GAUGES fuse.
