Tire Pressure Module: Service and Repair
Tire Pressure Monitoring System Module
Removal and Installation
CAUTION: Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage can result.
NOTE: The tire pressure monitoring system (TPMS) is integral to the smart Junction box (SJB) and is not serviced separately.
NOTE: A new SJB module is delivered in manufacturing mode with pre-set diagnostic trouble codes (DTCs). These DTCs require that a particular
set of operations to be carried out in order to clear them and enable the module for normal operations.
The pre-set DTCs are as follows:
^
B2477 - Module Configuration Failure/Mismatch
^
B2868 - Left Front Tire Pressure Sensor Fault
^
B2869 - Right Front Tire Pressure Sensor Fault
^
B2870 - Left Rear Tire Pressure Sensor Fault
^
B2871 - Right Rear Tire Pressure Sensor Fault
^
C2780 - ECU in Manufacturing Mode
NOTE: A reconfigured SJB may also set the above codes and will need to go through the same set of procedures as a new module to enable normal
operation.
1. NOTE: The steps included in the SJB removal and installation process are critical to tire pressure monitoring system operations and will permit a
new or reconfigured module to operate as intended. Each step is designed to carry out a particular operation and clear the manufacturing mode
DTCs. Once these DTCs are cleared, the new or reconfigured module will enter into normal operating mode.
Remove the SJB.
