Service and repair of the Smart Junction Box (SJB) should start with disconnecting the battery. The procedure for removing the SJB requires you to upload its configuration data to a diagnostic tool because the information is necessary for downloading into the new module after installation. Before accessing the SJB you must take off the floor console SJB cover followed by removal of the transmission selector lever bezel from the floor console finish panel. Engage the parking brake before removing the parking brake lever boot from the floor console finish panel which you should follow with removal of the floor console finish panel itself. You need to unscrew the SJB before disconnecting its electrical connectors to finally take out the SJB. Install the new SJB by first connecting its electrical connectors then placing the unit where it belongs before using the screw to secure it. You should reinstall the parking brake lever boot on the floor console finish panel while also releasing the parking brake before installing the transmission selector lever bezel and floor console SJB cover. Reconnect the battery. The SJB configuration data download from the diagnostic tool to the SJB will trigger the clearance of DTC B2477 thus signaling properly programming the SJB. Use diagnostic tool equipment to train the tire pressure sensors so the SJB will clear DTCs B2868, B2869, B2870, and B2871 till the sensors show recognition. Perform the SJB on-demand self-test to clear DTC C2780 because it enables the SJB to leave manufacturing mode before validating all other diagnostic codes. The diagnostic process should end with clearing all persistent DTCs while checking for any remaining DTCs.

The first step before SJB removal requires tool-based uploading of module configuration data that will be needed during new module installation. Start by removing the battery power followed by the floor console SJB cover and transmission selector lever bezel from the floor console finish panel. Shut off the parking brake and pull up the parking brake lever boot from the floor console finish panel before taking off the panel itself. Screw off the SJB before disconnecting its electrical connectors to take out the SJB device. The installation process for the new SJB begins with backward execution of removal steps followed by SJB configuration based on Information Bus (Module Communications Network) specifications.
