How to service the Air Bag Control Module on Mercury Mountaineer?

Service of the Air Bag Control Module needs proper orientation of the Restraints Control Module since its position determines system functionality. A vehicle that experienced a right cowl A-pillar collision must have its RCM mounting area inspected for both bracket and deformation damage which requires a replacement of the RCM unit even if the air bag failed to trigger. The mounting area must then be restored to its original design. Before performing any maintenance that requires back up power supply depletion the technician should disconnect the battery ground cable and wait one minute until any auxiliary batteries and power supplies are removed from the electrical circuit. This practice prevents accidental deployment and personal injuries. Static electricity should be avoided because electronic modules respond negatively to static electric charges. Start by unfastening the electrical ground connection on the battery and separate the right-hand side cowl side trim panel. The RCM requires both electrical connector locking clips down while the operator squeezes the locking clip area to pivot the latch before removal of the two electrical connectors. First extract the RCM and its bracket from their mounting position through bolt extraction of three retainers. To reinstall the RCM use the same reverse procedure of removal while setting correct torque values on its retaining bolts to achieve operational system performance. Check the air bag system operation after system setup. Keep the Restraint System Diagnostic Tool dedicated to service operations only because using it during road use creates safety hazards that could result in vehicle violations.
