Smart Junction Box (SJB): Installation

WARNING: This page is about a different car, the 2010 Lincoln MKX and 2010 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 pushpin into the SJB  .
  4. Connect the 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, B2477 and B2A21. The clearing of these DTCs indicates the calibration data has been successfully downloaded to the new SJB  .
    NOTE: The RKE  transmitter portion of the Integrated Keyhead Transmitter (IKT) key is automatically transferred during Programmable Module Installation (PMI). Passive Anti-Theft System (PATS) programming is not necessary. If As-Built data is required during PMI  , all (IKT  or fob) remote transmitters must be programmed to the new SJB  . Cycling the ignition to run for 6 seconds with each IKT  programs the RKE  function of the IKT  key. For additional information, refer to HANDLES, LOCKS, LATCHES AND ENTRY SYSTEMS for the remote transmitter programming instructions.
    NOTE: DTC B2276 may be set, indicating there are less than 2 transmitters programmed to the SJB  . For additional information, refer to HANDLES, LOCKS, LATCHES AND ENTRY SYSTEMS .
  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 does not clear if any other DTCs are present in the SJB  .
  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 dimmer switch rotation is a calibration procedure for the SJB  dimmer switch input and makes sure that all displays are visible under all lighting conditions.
