AIR BAG Warning Lamp Does Not Come On:

CIRCUIT DESCRIPTION
When you turn the ignition switch to the RUN position, the GAUGES Fuse applies voltage to the AIR BAG warning lamp that is connected to the inflatable restraint Sensing And Diagnostic Module (SDM) at terminal 7. The inflatable restraint Sensing And Diagnostic Module (SDM) is supplied IGNITION 1 voltage at terminal 10 via the AIR BAGS Fuse when the ignition switch is in the RUN position. The inflatable restraint Sensing And Diagnostic Module (SDM) responds by flashing the AIR BAG warning lamp 7 times. If IGNITION 1 voltage is outside of the normal operating voltage range (8.2-17.1 volts), the AIR BAG warning lamp will come ON solid with no DTCs set.

TEST DESCRIPTION
The numbers below refer to the 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 cluster power feed circuitry.
3. This test determines whether voltage is present in the warning lamp circuit.
4. This test isolates CKT 358 and inspects 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 inspects whether power is available to the instrument cluster power feed circuit.
14. This test inspects 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.
