Diagnosing and Clearing System Faults

DIAGNOSING AND CLEARING SYSTEM FAULTS
All Tire Pressure Monitoring System Faults are specific to one location. If a no-transmit, "LOW BATTERY", "LOW or HIGH PRESSURE" fault is detected, the location can be determined by the DRBIII. The appropriate Sensor/Transmitter can then be replaced or the out-of-spec pressure condition can be corrected.
- If a single Sensor/Transmitter cannot be detected by the EVIC, replace that Sensor/Transmitter.
- If none of the Sensor/Transmitters can be detected, refer to symptoms in the EVIC.
- If a BUCKET COUNTER test fails, and one or more Sensor/Transmitters does not transmit, replace the affected Sensor/Transmitter.
- If none of the Sensor/Transmitter causes the BUCKET COUNTER to advance, replace the EVIC.
- If the EVIC displays SERVICE TIRE PRESS. SYSTEM and the DRBIII sees no Sensor/ Transmitter fault or pressure out of specification,

1. attempt the Retrain procedure. If the display reoccurs,
2. replace the EVIC.
