Warning Lamp Comes "ON" Steady

Air Bag Warning Lamp Comes On Steady:

CIRCUIT DESCRIPTION
When the ignition switch is first turned ON, Ignition 1 voltage is applied from the GAUGES fuse to Redundant Indicator Ignition 1, terminal B2, and to the AIR BAG warning lamp which is connected to Supplemental Restraint System (SRS) Indicator, terminal B1. The AIR BAG fuse applies system voltage to the Ignition 1 inputs, terminals A9 and A10. The supplemental restraint Diagnostic Energy Reserve Module (DERM) Responds by flashing the AIR BAG warning lamp seven times. If Ignition 1 is outside of the normal operating voltage range, the AIR BAG warning lamp come on solid with no DTC set.

When the engine is being cranked, Ignition 1 voltage is applied from the CRANK fuse to the DERM at the Crank input. The DERM responds by grounding the SRS Indicator output until Ignition 1 voltage is removed from the Crank input. This results in the AIR BAG warning lamp being on during cranking.
After cranking, the DERM will flash the AIR BAG warning lamp six times.

TEST DESCRIPTION
Refer to step numbers on the diagnostic table.
1. Start at the SRS Diagnostic System Check for all diagnosis.
2. An open AIR BAG fuse would cause the AIR BAG warning lamp to come on steady.
3. A disconnected DERM harness connector will cause the warning lamp to come on steady via the shorting bar from terminal A1 to terminal B1.
9. This test checks for a open in the ground circuitry to the DERM.
11. This test checks for an open in the Ignition 1 circuitry to the DERM.
16. This test checks for a short from the Crank input to circuit to B+.
17. This test determines where the short-to-voltage is located in circuit 1035.

When measurements are requested in this table use J 39200 Digital Multimeter with 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. When a wire, connector or terminal repair is requested, use J 38125-A Terminal Repair Kit and refer to Wiring Repair.
