Smart Junction Box (SJB): Removal
NOTE:
- Prior to removal of the SJB, it is necessary to upload module configuration information to a IDS or equivalent tester.
NOTE:
- The tire pressure monitoring system (TPMS) functionality is integral to the SJB.
NOTE:
- The steps included in the SJB removal and installation procedure are critical to restoring the vehicle security and tire pressure monitoring systems to normal operation. A new SJB module is delivered in manufacturing mode with pre-set DTCs. These DTCs require that the TPMS sensor training procedure be carried out in order for the DTCs to be cleared. The pre-set DTCs are as follows:
- B106D - Tire Pressure Monitoring System (TPMS) Initiators Not Configured
- B2477 - Module Configuration Failure
- B2868 - Left Front Tire Pressure Sensor Fault
- B2869 - Right Front Tire Pressure Sensor Fault
- B2870 - Right Rear Tire Pressure Sensor Fault
- B2871 - Left Rear Tire Pressure Sensor Fault
- C2780 - ECU in Manufacturing Sub-State
NOTE: This step is necessary only if the SJB is being replaced.
- Upload the module configuration information from the SJB. For additional information, refer to PROGRAMMABLE MODULE INSTALLATION , .
- Remove the RH lower cowl trim panel.
- Disconnect the electrical connectors.
- Remove the 3 screws and the SJB.
