Multifunction Electronic Modules System: Removal & Installation Lincoln MKX I

REMOVAL AND INSTALLATION

Note. Prior to the replacement of the module, it is necessary to upload the module configuration information to the appropriate scan tool. This information must be downloaded into the new module after installation. For additional information, refer to MODULE CONFIGURATION article.

1. Upload the module configuration information from the DSM into the scan tool. For additional information, refer to «MODULE CONFIGURATION»(ref-292556) article.
2. If necessary, remove the driver seat. For additional information, refer to «SEATING»(ref-292552) article.
3. Remove the 2 screws.
4. Disconnect the 4 electrical connectors and remove the DSM.
5. To install, reverse the removal procedure.

REMOVAL

Note. Prior to the replacement of the module, it is necessary to upload the module configuration information to the appropriate scan tool. This information must be downloaded into the new module after installation. For additional information, refer to MODULE CONFIGURATION article. In the event that As-Built data is required (SJB will not communicate), all remote keyless entry (RKE) devices must be programmed to the new SJB. A minimum of 2 devices are necessary to complete the configuration and turn off the flashing interior lights.

Note. The tire pressure monitoring system (TPMS) functionality has been integrated into the smart junction box (SJB).

Note. The steps included in the smart junction box (SJB) removal and installation procedure are critical to restoring the vehicle security and tire pressure monitoring systems to normal operation. A new SJB is delivered in a manufacturing mode with 7 pre-set DTCs related to the TPMS. To clear the DTCs, successful configuration of the SJB must occur, followed by successful TPMS sensor training, and a successful self-test, including clearing of the DTCs. The DTCs are as follows: B106D (Tire Pressure Monitor System [TPMS] Initiators Not Configured) B2477 (Module Configuration Failure) B2868 (Left Front Tire Pressure Sensor Fault) B2869 (Right Front Tire Pressure Sensor Fault) B2870 (Right Rear Tire Pressure Sensor Fault) B2871 (Left Rear Tire Pressure Sensor Fault) C2780 (ECU in Manufacturer Sub-State)

1. Upload the module configuration information from the SJB into the scan tool. For additional information, refer to «MODULE CONFIGURATION»(ref-292556) article.
2. Remove the driver door scuff plate.
3. Disconnect the 6 electrical connectors.
4. Remove the harness pushpin from the SJB.
5. Remove the nut.
6. Lower the SJB (release the SJB from the 2 alignment holes).
7. Push the red lock tab upward and press the 2 black tangs inward to release the B+ connector from the SJB.
8. Remove the SJB.

INSTALLATION

1. Install the B+ connector onto the SJB and push the red lock tab downward.
2. Position the 2 SJB alignment tabs into the 2 holes and install the nut. Tighten to 5 Nm (44 lb-in).
3. Install the harness pushpin into the SJB.
4. Connect the 6 electrical connectors.
5. Install the driver door scuff plate.
6. Download the SJB configuration information from the scan tool to the new SJB. For additional information, refer to «MODULE CONFIGURATION»(ref-292556) article.
7. Train the tire pressure sensors. For additional information, refer to «WHEELS & TIRES»(ref-292521) article.
8. Carry out the SJB self-test (must include an on-demand self-test) and then repeat the self-test to confirm all DTCs have been cleared.
9. Rotate the instrument panel dimmer switch from the full dim position to the dome ON position. This will make sure that all displays are visible under all lighting conditions.
