Question 1

What are the safety precautions and procedures for servicing and repairing the Air Bag Control Module on Mercury Cougar?

Accepted Answer

Before servicing or repair of the Air Bag Control Module start by waiting for at least one minute after battery cable disconnection to disconnect electronic air bag control module or supplemental restraint system electrical connectors to prevent accidental air bag deployment that can result in personal injury. Safety glasses must be worn during air bag-equipped vehicle maintenance tasks as well as while handling the air bag module. The use of radio keycode savers during air bag system work should be avoided because it might activate the air bag deployment. Hands should position a live air bag away from their body by pointing it toward the floor with the trim cover facing up when it is necessary to handle deployed air bags. This technique reduces potential injuries in case of accidental air bag activation. Washing hands with soapy water becomes necessary after deployment because sodium hydroxide leavings on hands can induce skin irritation. A new part installation must serve as the repair method but if the new part fails to fix the issue the technician should re-install the original part followed by diagnostic procedure repetition. Testing the air bag connectors will expose the device to deployment along with creating risk of personal harm. Air bags that show discoloration or damaged coverages or deployment doors require immediate replacement with new manufactured parts. The first step starts with disconnecting the battery cable followed by removing the lower panel of instruments through the removal of four bolts and covers. Users should disconnect the electronic air bag control module electrical connector by pushing the retaining tang until the two-stage self-locking connector can be released. You need to remove the electronic air bag control module as the final step of the process. The installation procedure should reverse the removal steps.

Question 2

What precautions should be taken when servicing the air bag control module and RCM on Mercury Mariner?

Accepted Answer

Safety glasses should always be worn when servicing an air bag control module because accidental deployments present injury risks. Proper operation of the supplemental restraint system (SRS) relies on the correct position of the restraints control module (RCM). A damaged center tunnel area caused by collision requires a new RCM replacement for the system even when the air bags did not deploy. The RCM demands its original horizontal position while connected and the ignition is ON to prevent unintended safety canopy activation. Using memory saver devices creates additional risks of personal injuries to the technicians. Electronic modules react poorly to static electricity because it creates destructive consequences. Installing a new RCM requires using the correct part to prevent the generation of erroneous diagnostic trouble codes (DTCs). The RCM fuse removal with ignition ON activation will cause the air bag warning lamp to light up but this action does not indicate an SRS problem. A vehicle should only be handed over to customers after completing a full operational check that shows no faulty SRS conditions. Replacement of a new component constitutes the proper repair method after which the installer must reinstall the original part before running a second diagnostic check. You must first depower the system before accessing the RCM by removing the lower LH center instrument panel finish panel together with repositioning the carpet on the LH and RH tunnel area. The thumbs-tab on the large RCM electrical connector activates the connector release mechanism which lets you pivot the connector position assurance lever back and remove the connector. Users should disconnect the small RCM electrical connector while they remove the three bolts attaching the RCM. Position the RCM before threading in the three bolts while tightening them to 11 Nm (8 lb-ft). Ensure the connector position assurance lever is completely unlocked before connecting both the small and large RCM electrical connector pins. The large connector should be installed straight to maintain proper connections and protect both components from damage. Push the large connector gently until it clicks audibly before you activate the connector position assurance lever. Repower the system only after the removal of carpet and installation of the lower LH center instrument panel finish panel.
