2004 Lincoln Town Car Air Bag Control Module Parts Questions & Experts Answers

• Q: What is the Importance of the Air Bag Control Module in the Supplemental Restraint System and What Steps Should Be Taken if It Is Damaged on 2004 Lincoln Town Car?

  A: The restraints control module functions as the SRS controller so it requires proper installation position for operational success. Vehicle owners must inspect the mounting and bracket for deformation after any collision that hit the center tunnel area because RCM replacement is necessary even when air bags did not deploy. The team should utilize head protection during all SRS repairs along with keeping away from memory saver devices to prevent harm. Electronic modules readily receive static electricity that leads to damaging effects on their functionality. When the RCM fuse removal takes place during ignition ON the warning lamp will illuminate to show regular system operation without any fault. It is essential to ensure SRS functional integrity along with no faults when giving the vehicle back to customers. All SRS maintenance must use new components. The procedure to remove the RCM begins by system depowering followed by releasing tabs on carpet patch and ashtray to separate them from the system. Before installation of the ash tray bracket you need to remove the screws and then unfasten the RCM insulator before you remove its bolts. When removing the RCM disconnect its electrical connectors through simple clip disengagement and tab pivoting maneuvers. To install the RCM users should connect its electrical connectors followed by engaging locking clips and adjusting RCM retaining bolts to maintain correct system operating torque. The RCM should go in the center tunnel space beneath the instrument panel and installation must include bolts along with placing the insulator on top of the RCM. Replace the ash tray bracket with its screws then install the ash tray and cover the carpet area with its replacement. The SRS requires immediate reactivation after bypassing the system initial testing phase. The installation of a new RCM requires module configuration because the continuous fault code B2477 stores within memory space will activate LFC 54 on the air bag indicator. Proving out the SRS system requires pausing between the ON and OFF positions of the key for ten seconds followed by turning the ignition to ON. Watch the air bag indicator which should stay on for six seconds before shutting off. A related issue will cause the indicator to display continuous problems by not turning on or staying illuminated then possibly flashing at the same time with specific sounds. The RCM requires a scan tool to eliminate all persistent DTCs.
