Mountaineer 4WD V6-4.0L VIN E (1999)
Air Bag Control Module: Service and Repair
REMOVAL
WARNING:
-
The Restraints Control Module (RCM) orientation is critical for proper system operation. If a vehicle equipped with an air bag
Supplemental Restraint System (SRS) has been involved in a collision in which the right cowl A-pillar area has been damaged, inspect the
mounting and bracket for deformation. If damaged, the RCM must be replaced whether or not the air bags have deployed. In addition,
make sure the area of the RCM mounting is restored to its original condition.
-
To avoid accidental deployment and possible personal injury, the backup power supply must be depleted before repairing or replacing
any front or side air bag supplemental restraint system (SRS) components and before servicing, replacing, adjusting or striking
components near the front or side air bag sensors, such as doors, instrument panel, console, door latches, strikers, seats and hood latches.
The side air bag sensors are located at or near the base of the B-pillar.
To deplete the backup power supply energy, disconnect the battery ground cable and wait at least one minute. Be sure to disconnect auxiliary
batteries and power supplies (if equipped).
CAUTION: Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage can result.
NOTE: Repair is made by installing a new part only. If the new part does not correct the condition, install the original part and perform the diagnostic
procedure again.
1. Disconnect the battery ground cable and wait at least one minute.
2. Remove the right hand cowl side trim panel.
