2007 Lincoln Navigator Air Bag Control Module Parts Q&A

• Q: What Precautions Should Be Taken When Servicing the Air Bag Control Module on 2007 Lincoln Navigator?

  A: Every service encounter with the Restraints Control Module (RCM) requires safety glasses to protect against air bag accidents. When connected to power and the ignition is ON do not touch or modify the existing RCM horizontal position since it might activate the safety canopy unintentionally. Check that the RCM maintains its correct position for air bag activation while inspecting for damage when the vehicle has experienced an impact. The installation of a new RCM is necessary if deformation is detected even without air bag deployment. Memory saver devices should be avoided because they elevate the possibility of injuries to technicians. The electronic modules exhibit sensitivity to static electricity because exposure to it may lead to substantial damage. New RCM installation should begin with programmable module installation (PMI) to avoid registering false diagnostic trouble codes (DTCs) through using the proper replacement part. The first step requires power suspension and removal of the center console when necessary. Motorists should first remove the three RCM push-nut retainers along with the RCM cover on vehicles that lack center console installation. First disconnect the small RCM electrical connector by depressing the retaining tab until it releases. Then extract the connector. First disconnect the large RCM electrical connector through the process of pinching the thumb tab followed by rotating the connector position assurance lever opposite to the RCM direction to extract the connector. Use a tool to detach the RCM through removing its three securing bolts. Installation of the RCM requires 11 Nm (8 lb-ft) torque on retaining bolts while maintaining full position release on the connector assurance lever before large electrical connector attachment. Align the electrical connector properly by applying light pressure while ensuring noise of the audible click for connector alignment. Rotation of the assurance lever towards the RCM will secure the connector when the thumb tab reaches its locked position. Built the small RCM electrical connector before re-installing the RCM cover and push-nut retainers if needed or using the center console if present. The SRS system needs immediate power up before completion of proof testing. The SRS proof testing requires turning the ignition from ON to OFF with a 10-second wait and returning to ON to check the warning indicator. After activating it should display illumination for 6 seconds prior to complete power off. The SRS requires a diagnostic and repair process if the warning light fails to appear and stays on or starts flashing. A pattern of five times five beeps will play from the speaker when the indicator shows no signs of activity due to a present fault. After finishing merchant procedures users need to wipe all ongoing DTCs recorded in the RCM memory.
