Malfunction Lamp / Indicator: Testing and Inspection
Warning Lamp Comes "ON" Steady
Circuit Description
When the ignition switch is first turned to the RUN position, the GAUGES fuse applies battery voltage to the AIR BAG warning lamp. The AIR BAG
warning lamp is connected to the supplemental RESTRAINT INDICATOR, terminal 7. The SIR fuse applies battery voltage to the Air Bag Indicator
Control, terminal 10. The supplemental restraint sensing and diagnostic module (SDM) flashes the AIR BAG warning lamp 7 times. If IGNITION is
outside of the normal operating voltage range (8.2 - 17.1 volts), the AIR BAG warning lamp turns ON solid with no DTCs set.
Diagnostic Aids
In order to disable the shorting bar from terminal 6 to terminal 7 inside the SDM harness connector, the following two 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.
