Lincoln Navigator: Multifunction Electronic Modules / Body Control Module (BCM). Removal and Installation

Removal

NOTE: Removal steps in this procedure may contain installation details.

1. If installing a new BCM , connect a battery charger to the battery to make sure it is charged to maintain proper battery voltage.
   Refer to: Battery Charging (414-01 Battery, Mounting and Cables, General Procedures).
   

1. NOTE: Before replacing the BCM (body control module), ensure that two correct keys are present as they will be needed to complete the PMI (programmable module installation) with the FDRS scan tool. The vehicle will not start unless two keys are present.

   NOTE: If the BCM did not respond to the diagnostic scan tool, As-Built Data may need to be entered as part of the repair. This step is only necessary if the BCM is being replaced.

   Using a diagnostic scan tool, begin the PMI process for the BCM following the on-screen instructions.

1. Remove the BCM access cover.
   

1. 1. Position aside the RH side front lower weatherstrip.
      
   2. Release the rearward clips on RH side front scuff plate.
      
   3. Release the forward clips and remove the RH side front scuff plate.
      

1. Disconnect the electrical connectors and release the wire harness retainers.
   

1. Remove the screw and the BCM .
   

Installation

1. To install, reverse the removal procedure.
   

NOTE: Carry out the remaining steps only if installing a new BCM .

1. NOTE: The PMI (programmable module installation) application in the scan tool will guide you through completing the BCM (body control module) programming and key programming.

   Run the PMI on the BCM .
   

1. After keys have been programmed as directed by the on screen prompts, and the BCM programming has fully completed (as indicated by a module installation complete or successful message), carry out the PATS Module Initialization using the FDRS Scan Tool PATS Application.
   

1. As directed by the scan tool, follow the onscreen promts to relearn the TPMS sensors.
   Refer to: Tire Pressure Monitoring System (TPMS) Sensor Location Calibration (204-04B Tire Pressure Monitoring System (TPMS), General Procedures).
   

1. If equipped with a video rear parking aid (rear mounted only), using a diagnostic scan tool, carry out the LIN New Module Initialization function.
   

1. Using a diagnostic scan tool, carry out the BMS Learned Values Reset.
   

1. Configure the BCM Programmable Parameters.
   Refer to: Module Programming (418-01A Module Configuration, General Procedures).
   

1. Using a diagnostic scan tool, carry out the BCM self-test (must include an on-demand self-test) and then repeat the self-test to confirm all DTC have been cleared.
   

1. NOTE: This step only applies to vehicles without a stand-alone PAM (parking assist control module).

   Using a diagnostic scan tool, complete the PMI process for the PAM following the on-screen instructions.
   Refer to: Controller Area Network (CAN) Module Communications Network - System Operation and Component Description (418-00A Controller Area Network (CAN) Module Communications Network, Description and Operation).
