Smart Junction Box (SJB): Installation

WARNING: This page is about a different car, the 2009 Mercury Milan, 2009 Lincoln MKZ, and 2009 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

Position the SJB and install the 2 nuts.
- Tighten to 5 Nm (44 lb-in).

NOTE: If the SJB is not being replaced, this is the last step that is necessary.

Connect the 6 electrical connectors.

NOTE: When successful, this step provides the calibration necessary for the SJB operation and clears the DTCs B106D and B2477. The clearing of these DTCs indicates the calibration data has been successfully downloaded to the SJB.

NOTE: If the 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. For additional information, refer to ANTI-THEFT - PASSIVE ANTI-THEFT SYSTEM (PATS) article.

Download the SJB configuration information from the scan tool to the SJB. For additional information, refer to MODULE CONFIGURATION article.

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.

Train the tire pressure sensors. For additional information, refer to WHEELS AND TIRES article.

NOTE: DTC C2780 will not clear if any other DTCs are present in the SJB.

Carry out the SJB on-demand self-test by clearing the DTCs and then retrieving the DTCs to confirm all DTCs have been cleared.
