Tire Pressure Module: Service and Repair
TIRE PRESSURE MONITORING SYSTEM MODULE REMOVAL/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 SJ13 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.
Note
^
The steps included in the SJB removal and installation process are critical to tire pressure monitoring system (TPMS) 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.
1. Remove the SJB.
