Malfunction Lamp / Indicator: Testing and Inspection
Warning Lamp Does Not Come "ON"
Air Bag Warning Lamp Does Not Come On
CIRCUIT DESCRIPTION
When you first turn the ignition switch ON, the GAUGES fuse applies Ignition 1 voltage to the 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 input terminals A9 and A10. The supplemental restraint Diagnostic Energy Reserve Module (DERM) then flashes
the AIR BAG warning lamp seven times. If Ignition 1 is outside of the normal operating voltage range, the AIR BAG warning lamp will come on
solid with no DTCs set.
During engine cranking, the CRANK fuse applies ignition 1 voltage to the DERM at the Crank input. The DERM then grounds the SRS Indicator
output until Ignition 1 voltage is removed from the Crank input. The AIR BAG warning lamp being then comes on during cranking.
After cranking, the DERM flashes the AIR BAG warning lamp six times.
