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

  A: The service of air bag control modules requires safety glasses to prevent injuries that may occur from accidental air bag activation. A correct orientation of the restraints control module (RCM) is necessary for proper air bag operation thus inspect the RCM mounting and bracket for deformation after any collision that damaged the center tunnel area; replace the module if it shows any damage. The use of memory saver devices to protect from personal injuries should be avoided by technicians. Vehicle owners should install the appropriate RCM because safety curtain and side air bag version connectors differ from standard models while connector force can damage the system. The modules inside your vehicle exhibit sensitivity to static electricity therefore proper protection measures should always be followed. Prepare all new configuration data through the diagnostic tool before removing the module to use during the new module installation. A warning lamp from the RCM fuse becomes activated during ignition ON conditions but signifies only a normal system state without any failure. It is crucial that the SRS functions without flaws when the customer receives the vehicle and new part replacements must be used for all repairs. The sequence to remove the RCM consists of these steps: depower the system, remove the two right-hand side retaining bolts, arrange the carpet one way, disconnect the big connector along with the small connector and completely extract the module from its location. Total Installation success requires new RCM configuration before mounting followed by retaining bolt tightening to 12 Nm (9 lb-ft). First align the large connector and then connect the small electrical connector while applying light force so that the position assurance lever can be engaged. An operator should execute a download of saved configuration information to the new RCM after finishing SRS repowering. The verification process for the SRS begins by turning ignition from ON to OFF for 10 seconds before returning to ON position while checking the air bag indicator which will stay on for around 6 seconds before turning off. When the indicator fails to show light or stays lit or flashes at 5 Hz rate it is necessary to diagnose and rectify any existing faults. A diagnostic tool should be used to erase all ongoing diagnostic trouble codes that exist in both RCM and occupant classification sensor (OCS) modules.
