Camaro V6-3.8L VIN K (1995)
Standby Power Supply: Description and Operation
DESCRIPTION
The Diagnostic Energy Reserve Module (DERM) performs several system functions. These functions include energy reserve, malfunction detection,
malfunction recording, driver notification and frontal crash recording.
OPERATION
The DERM is connected to the SIR wiring harness by a 24-way connector. This harness connector uses a shorting bar across certain terminals in the
contact area. This shorting bar connects the AIR BAG warning lamp to ground when the DERM harness connector is disconnected. This will cause the
AIR BAG warning lamp to come on steady whenever the ignition switch is at the Run, Bulb Test or Start positions with the DERM disconnected.
