Smart Junction Box (SJB): Installation

Position the SJB into the 3 keyholes of the SJB bracket and slide it downward until the SJB locking tab snaps into place.

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

Connect the 7 electrical connectors.

NOTE: If the Programmable Module Installation (PMI) procedure was not followed when a new SJB was installed, the Remote Keyless Entry (RKE) function (from the Integrated Keyhead Transmitter (IKT)) of the SJB must be programmed, or the IKTRKE functions is 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 Panel Cluster (IPC) was installed, the IKT keys must be programmed to the new IPC. For additional information, refer to ANTI-THEFT - PASSIVE ANTI-THEFT SYSTEM (PATS) .

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

NOTE: DTC C2780 cannot be cleared if any other DTCs are present in the SJB. When successful, this step clears the DTC C2780.

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