Malfunction Lamp / Indicator: Description and Operation
The AIR BAG warning lamp notifies the driver of SIR system malfunctions. Ignition voltage is applied to the AIR BAG warning lamp when the ignition
switch is at the RUN or START positions. The inflatable restraint Diagnostic Energy Reserve Module (DERM) controls the lamp by providing ground
with a lamp driver. The AIR BAG warning lamp does the following tasks:
1. Verifies lamp and DERM operation. The lamp will flash seven times when the ignition switch is first turned ON.
2. Warns the vehicle driver of SIR electrical system malfunctions. These malfunctions may potentially affect the operation of the SIR system.
Electrical system malfunctions may result in either of the following conditions:
^
Non-deployment in the case of a frontal crash
^
Deployment for conditions less severe than intended
