Removal

NOTE:
- Prior to removal of the SJB, it is necessary to upload module configuration information to a scan tool.
- The tire pressure monitoring system (TPMS) functionality is integral to the SJB.
- 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:
- B2868 - Left Front Tire Pressure Sensor Fault
