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 replaced 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:
^
82477 - Module Configuration Failure/Mismatch
^
B2868 - Left Front Tire Pressure Sensor Fault
^
B2869 - Right Front Tire Pressure Sensor Fault
^
82870 - Left Rear Tire Pressure Sensor Fault
^
82871 - 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.
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.
1. Remove the SJB. See SMART JUNCTION BOX (SJB).
