Power Distribution Module: Service and Repair

SMART JUNCTION BOX (SJB)







Removal and Installation

CAUTION: Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage may result.

NOTE: Prior to the removal of the module, it is necessary to upload the module configuration information to the appropriate scan tool. This information needs to be downloaded into the new module once installed.

1. Upload the module configuration information from the SJB into the scan tool.
2. Disconnect the 6 electrical connectors.
3. Remove the 2 nuts.
- To install, tighten to 5 Nm (44 lb-in).

4. Position the SJB aside, disconnect the RKE antenna electrical connector and remove the SJB.

5. NOTE: If the PMI procedure was not followed when a new SJB was installed, the RKE function (from the integrated keyhead 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.

To install, reverse the removal procedure.
- Download the SJB configuration from the scan tool into the new SJB.
