Smart Junction Box (SJB): Installation

WARNING: This page is about a different car, the 2007 Lincoln MKX and 2007 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
  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 push pin into the SJB.
  4. Connect the 6 electrical connectors.
    5. NOTE: If the SJB was not replaced, this is the last step that is necessary.
  5. Install the driver door scuff plate.
    6. NOTE: When successful, this step provides the calibration necessary for the SJB operation and clears DTCs B106D and B2477. The clearing of these DTCs indicates the calibration data has been successfully downloaded to the new SJB.
    NOTE: If the programmable module installation (PMI) procedure was not followed when a new SJB was installed, the remote keyless entry (RKE) function (from the integrated key head transmitter [IKT]) of the SJB must be programmed, or the IKT RKE functions will be inoperative. IKTs can be programmed to the new SJB by cycling each IKT key to the ON position for a minimum of 6 seconds. If a new instrument cluster was installed, the IKT keys must be programmed to the new instrument cluster in order to program both the RKE and passive anti-theft system (PATS) functions. For additional information, refer to ANTI-THEFT - PASSIVE ANTI-THEFT SYSTEM (PATS) .
  6. Download the SJB configuration information from the scan tool to the new SJB. For additional information, refer to MODULE CONFIGURATION .
    7. NOTE: When successful, this step clears DTCs B2868, B2869, B2870 and B2871. The clearing of these DTCs indicates the SJB has recognized the tire pressure sensors during the training procedure.
  7. Train the tire pressure sensors. For additional information, refer to WHEELS AND TIRES .
    8. NOTE: DTC C2780 will not clear if any other DTCs are present in the SJB.
  8. Carry out the SJB on-demand self-test, clear DTCs, and then retrieve all DTCs to confirm all DTCs have been cleared.
