Diagnostic Energy Reserve Module (DERM): Service and Repair
Prior to performing replacement procedures, disarm air bag system. Refer to, Service and Repair/ Air Bag System Disarming & Air Bag
System Arming. Refer to, / Specifications/ Mechanical for torque values when installing components.
All sensors and mounting bracket bolts must be carefully torqued to assure proper operation. Never power up the air bag system when any
sensor is not rigidly attached to the vehicle, since the sensor could be activated when not attached, causing air bag deployment.
Do not open DERM case for any reason. Touching connector pins or soldered components may cause electrostatic discharge damage. Repair of a
malfunctioning DERM is by replacement only.
1. Remove instrument panel lower extension compartment.
2. Remove Connector Position Assurance (CPA) lock, then disconnect DERM electrical connector from DERM.
3. Remove DERM from mounting bracket.
