Smart Junction Box (SJB): Installation

WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
  1. Install the SJB  .
    • Install the 2 bolts.
    • Connect the 7 electrical connectors.
  2. Install the transmission selector lever bezel into the floor console finish panel.
    3. NOTE: If the SJB  was not replaced, this is the last step that is necessary.
  3. Install the floor console SJB  cover.
    4. 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 remote transmitters (IKT  or fob) 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 DESCRIPTION AND OPERATION for the remote transmitter (fob only) programming instructions, if necessary.
    NOTE: DTC B2276 may be set, indicating there are less than 2 transmitters programmed to the SJB  . For additional information, refer to DIAGNOSIS AND TESTING .
  4. Download the SJB  configuration information from the scan tool. For additional information, refer to INSPECTION AND VERIFICATION .
    5. 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.
  5. Train the tire pressure sensors. For additional information, refer to TIRE PRESSURE MONITORING SYSTEM (TPMS) SENSOR TRAINING .
    6. NOTE: DTC C2780 does not clear if any other DTCs are present in the SJB  . When successful, this step clears DTC C2780.
  6. 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.
  7. Rotate the instrument panel dimmer switch from the full dim position to the dome ON position. This makes sure that all displays are visible under all lighting conditions.
