Tire Monitoring System: Testing and Inspection

DIAGNOSIS AND TESTING - TIRE PRESSURE MONITORING SYSTEM
Diagnostics for the electronic components of the tire pressure monitoring system can be done using the DRBIII scan tool and Appropriate Diagnostic Information.
The tire pressure sensors/transmitters and TPM module are not repairable components. If either of these components are found to be at fault or damaged, the component must be replaced.
