2006 Lincoln Town Car Air Bag Control Module Parts Questions & Experts Answers

• Q: What precautions should be taken when servicing the air bag control module and what steps are involved in the proper installation and configuration of the restraints control module (RCM) on 2006 Lincoln Town Car?

  A: Wear safety glasses always when you perform maintenance on the air bag control module to prevent accidental deployment injuries. Proper function of the supplemental restraint system (SRS) depends entirely on appropriate orientation of the restraints control module (RCM). The center tunnel area damage from any previous collision requires an RCM mounting and bracket inspection for deformities as a replacement is necessary even without air bag deployment. The RCM mounting area needs to be returned to its factory state while memory saver devices should be avoided to minimize potential harm to technicians. The RCM retaining bolt torque specification needs to be set at 9 lb-ft and 12 Nm. The repair process should start with system deactivation followed by carpet removal together with ashtray disassembly. You need to free the tabs and disconnect cigarette lighter wires and harnesses. Begin by laying aside the ashtray bracket then taking off the RCM insulator before removing its right-hand side bolts. Remove the RCM bolt from the left-hand side after disconnecting both the large and small RCM electrical connectors. Extract the RCM. The RCM installation starts with placement of the component followed by tightening bolts on the right-hand side to 12 Nm (9 lb-ft). Begin by attaching the small RCM electrical connector then put in the left-hand side bolt before finally confirming the connector position assurance lever is free of blockage for proper large RCM electrical connector connection. Deform the large connector properly to prevent damage before you gently push it until the click sound appears and verify that the thumb tab connects correctly. Place the insulator above the RCM and fasten the ashtray bracket along with its screws. Then connect the cigarette lighter followed by carpet patch installation. Turn on the SRS system power without performing an initial system debugging procedure. A newly installed RCM requires module configuration since the continuous fault identified by diagnostic trouble code B2477 will remain in memory storage. Users must follow this SRS proving procedure by turning the ignition key from ON to OFF position followed by a 10-second waiting period then switching to ON position while inspecting the air bag indicator until it glows for six seconds and turns off. A fault in the system will cause the indicator to malfunction by refusing to turn on or staying on indefinitely or flashing continuously. In such cases warning sounds might emerge. A diagnostic tool must be used to delete continuous DTCs stored in the RCM.
