AIR BAG Warning Lamp Comes On Steady:

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.

DIAGNOSTIC AIDS
In order to disable the shorting bar from terminal 6 to terminal 7 inside the inflatable restraint Sensing And Diagnostic Module (SDM) harness connector, the following 2 conditions must be met:
^ The SDM harness connector must be properly connected to the SDM.
^ The Connector Position Assurance (CPA) must be properly installed in the SDM harness connector.

When measurements are requested in this table, use the J 39200 Digital Multimeter with the correct terminal adapter from the J 35616-A Connector Test Adapter Kit. When an inspection for proper connection is requested, refer to Testing for Intermittent and Poor Connections in Diagrams. When a wire, connector or terminal repair is requested, use the J 38125-B Terminal Repair Kit. Refer to Wiring Repairs in Diagrams.

TEST DESCRIPTION
The numbers below refer to the step numbers on the diagnostic table:
2. This test inspects for sufficient IGNITION 1 voltage applied to the SDM.
3. This test inspects for excessive IGNITION 1 voltage applied to the SDM.
4. This test inspects for a properly installed CPA.
6. This test determines if the SDM is turning on the AIR BAG warning lamp.
7. This test inspects for a damaged shorting bar.
9. This test determines whether the malfunction is a short to ground in CKT 358.
10. This test inspects for a short between CKTs 358 and 1751.
14. An open AIR BAGS Fuse would cause the AIR BAG warning lamp to come on steady.
15. This test inspects whether a short to ground caused the AIR BAGS Fuse to open.
16. This test determines whether the short to ground is due to a short in the wiring or internal to the SDM.
20. This test inspects for a disconnected SDM.
26. This test inspects for an open in the IGNITION 1 circuit.
