  Q: What precautions should be taken when servicing the air bag control module on Mercury Monterey?

  A:

  Safety glasses should always be worn when servicing the air bag control module to prevent possible injuries during accidental deployment. Changing or handling the original horizontal position of the restraints control module (RCM) with ignition ON creates a risk of safety canopy deployment. Check the orientation of the RCM before starting SRS operation while performing a check of the RCM for any mounting or bracket deformation when the vehicle experiences center tunnel damage irrespective of air bag deployment. Vehicle sensor orientation needs close examination because inspection of the sensor mounting bracket along with the wiring pigtail should check for damage after any collision and replace all damaged SRS components. Using memory saver devices creates a risk of personal injury so they should be avoided. The 40-pin connector of the RCM needs verification before installation because it shows differences between vehicles with safety canopies or side air bags. Compulsory insertion of the connector will negatively affect both the RCM and connector system. The electronic system is quite sensitive to static discharges since these can trigger damaging effects. The RCM fuse removal results in the air bag warning lamp illumination during the ignition ON stage which represents a normal condition with no SRS fault indication. Full operation and fault-free status of the SRS must be confirmed before the vehicle is handed over to the customer. The repair starts with installing fresh components but you should reinstall the original part if the problem keeps happening and then retest again. The process to remove RCM starts with system depowering then removing the four utility compartment scrivets before disconnecting electrical connectors followed by removing the utility compartment itself. Cable the large RCM electrical connector free by sliding the thumb tab and rotating the connector position assurance lever backward followed by removing the connector. First disconnect the small RCM electrical connector before extracting the RCM bracket bolts to remove the RCM bracket together with the RCM from the system. To install situate RCM bracket and RCM within the vehicle then fasten the four RCM bracket bolts to 12 Nm (9 lb-ft) to ensure system functionality. Before connecting the large RCM electrical connector fully release its position assurance lever while avoiding any angle on the connector to prevent connection problems and component destruction. Slightly insert the large RCM connector until it clicks audibly afterward use the connector position assurance lever to lock the connector secure by making sure the thumb tab activates. Link the small RCM electrical connector before replacing the utility compartment with its four scrivets while restarting the system power.
