Cutlass Ciera Cruiser V6-3300 3.3L MFI VIN N (1993)
Malfunction Lamp / Indicator: Description and Operation
Battery voltage is applied to the "INFLATABLE RESTRAINT" Indicator when the Ignition Switch is at the RUN, BULB TEST or START positions.
The DERM controls the lamp by providing ground with a lamp driver. The "INFLATABLE RESTRAINT" Indicator is used in the SIR System to do the
following:
1)
Verify lamp and DERM operation by flashing 7 to 9 times when the Ignition Switch is first turned to RUN.
2)
Warn the driver of SIR electrical system faults that could potentially affect the SIR System operation. These faults could result in nondeployment
during a frontal crash, or deployment for conditions less severe than intended.
3)
Provide diagnostic information by flashing the fault codes when the flash code diagnostic mode is enabled.
The "INFLATABLE RESTRAINT" Indicator is the key to driver notification of SIR System faults.
