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

Install the RH A-pillar lower trim panel.

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 SJB .

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 .

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

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 & TIRES .

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

NOTE: This step is required to clear the SJB DTC C2780, allow the SJB to exit the manufacturing mode, and to make sure there are no other concerns with the newly programmed SJB .

Carry out the SJB self-test (must include an on-demand self-test) and then repeat the self-test to confirm all SJB DTCs have been cleared.
