Smart Junction Box (SJB): Installation

WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 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 B2477 and B106D. 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 will program the RKE function of the IKT key. For additional information, refer to HANDLES, LOCKS, LATCHES AND ENTRY SYSTEMS article 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 article.
  4. Download the SJB configuration information from the scan tool. For additional information, refer to MODULE CONFIGURATION article.
    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 WHEELS AND TIRES article.
    6. NOTE: DTC C2780 will not clear if any other DTCs are present in the SJB. When successful, this step will clear 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 will make sure that all displays are visible under all lighting conditions.
