Q: What precautions should be taken when servicing the passenger air bag module on Mercury Mariner?
A: Safety glasses should always be worn during passenger air bag module service to protect yourself from unintentional deployments. The living air bag module requires handling with its air bag and deployment door facing away from your body while keeping the deployment door in a vertical position at all times. It is necessary to wash your hands with soap and water after deployment to eliminate sodium hydroxide that could cause skin irritation. It is essential not to probe connectors on air bag modules because this action might trigger deployment and to replace discolored or damaged deployment doors by disposing of defective units instead of attempting to repaint them. Memory saver devices must not be used since they enhance the risks of personal injuries. When the ignition switch is turned ON the air bag warning lamp lights up because the restraints control module (RCM) fuse is removed but this normal condition does not indicate any faults. A comprehensive check of the SRS system needs to establish complete functionality before a vehicle returns to the customer. For repairs use new components and re-rerun diagnostics if original components cannot resolve system issues. Uninstalling the passenger air bag module requires system depowering while opening then lowering the glove compartment door followed by disconnecting the electrical connector and unbolting the four securing components. Gently lift up through the glove box opening to unclip the three deployment door pins from the instrument panel and position the module lower end outside of the clips to prevent their reengagement. A complete removal of the module requires releasing all three clips positioned at the top deployment door section. When installing the module first position the J-clips before putting the module into place then insert the trim cover before aligning the pins to activate the deployment door retainers. Secure the module using four bolts then tighten them to 8 Nm, after which reconnect the electrical connector before closing the glove compartment and powering up the system.
Q: How Can You Safely Service and Deploy an Air Bag on Mercury Grand Marquis?
A: Wear safety glasses at all times when you serve an air bag supplemental restraint system (SRS) within a vehicle due to the threat of accidental deployment injuries. Place a live air bag module under your control with its air bag together with its trim cover or deployment door facing away from your body for protection against injuries. The deployment must occur outside in addition to keeping all personnel greater than 6.1 meters (20 feet) from the device because loud sounds will emerge during operation and ear protection is mandatory. The forces of air bag module deployment will create dangerous reflections when the trim cover or deployment door points downwards which could lead to injuries. Begin driver air bag deployment by removing the component from the automobile then making electrical connector wire cuts and stripping wires before attachment of wires. Use two 6.1 meter (20 foot) long wires with a minimum 20 gauge thickness for connecting to the stripped ends of the driver air bag module wires. Position the air bag module flat on the ground in an outdoor public area where its trim cover points up and always stand at least 6.1 meters (20 feet) distant. Complete air bag deployment by wiring the battery terminals to the two ends of the two wires. It is essential to take at least ten minutes for cooling following deployment before touching the air bag module and standard scrap procedures must be followed for its disposal.
Q: How to service the driver air bag module safely on Mercury Cougar?
A: It is essential to disconnect the battery cables first then wait one minute before you disconnect any prompts of the electronic air bag control module or supplement safety restraint electrical connectors to stop accidental air bag deployment leading to the possibility of injuries. The air bag module requires protection from safety glasses during handling but keep a live air bag beside you as you point the bag and trim cover away from your body to prevent accidental deployment injuries. Put a live air bag on its surface with the trim cover upward and afterward clean your hands with water and soap to eliminate sodium hydroxide skin irritation. A new part replacement must be carried out first; failing that the original component should be reinstalled while repeating the diagnostic test. Danger exists when you probe the air bag's connectors since this could cause them to deploy or result in personal injuries. After turning the steering wheel perform the driver air bag module removal by locating and removing retaining Torx screws from the back of the steering wheel cover and disconnect both components manually. Installation should be performed in reverse order with full attention to all safety measures. The vehicle may experience abnormal driving symptoms following battery disconnect and reconnect because the adaptive strategy needs to be relearned after driving at least 16 km (10 miles) to resume normal behavior. The replacement of air bag modules applies when the cover shows discoloration or deployment doors exhibit damage rather than painting over them.
