What are the critical procedures involved in the Air Bag Control Module service for proper system operation on Mercury Grand Marquis?

A correct system operation requires specific installation and removal procedures as part of the Air Bag Control Module service. Start the process by disconnecting the battery ground cable followed by waiting one minute to drain back up power supply energy while simultaneously removing all auxiliary batteries and power supplies. To reach the Electronic Crash Sensor (ECS) the right-hand sill plate must be removed and the carpet needs to be placed aside. Pull off both the ECS electrical connector locking clip and connector before you remove the ECS module and bracket by taking out its three screws. After reversing the removal process properly set the ECS towards its correct orientation before conducting installation steps especially when the right cowl A-pillar area has suffered collision damage check the ECS mounting for any signs of deformation and replace only if necessary regardless of air bag status. The ECS installation requires a fresh unit that should be implemented after any air bag module replacement while also performing proper torque specifications on the retaining screws to validate system functionality. The reinstallation must include system checking after which the restraint tool must be taken out to prevent safety hazards and standards violations.
