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 (TPM's) is integral to the vehicle security module (VSM) and is not serviced separately.
NOTE: A new VSM module is delivered in manufacturing mode with pre-set diagnostic trouble codes (DTC's). These DTC's 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 DTC's 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 re-configured VSM 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 VSM removal and installation process are critical to restoring vehicle security and 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 DTC's. Once these DTC's are cleared, the new or
reconfigured module will enter into normal operating mode.
Remove the VSM.
