TIRE PRESSURE MONITORING SYSTEM
All Tire Pressure Monitoring System Faults are specific to one location. If a "BATTERY LOW" fault is detected it will cause a loss of signal fault. If a "SENSOR FAILURE" fault is detected, the location will be displayed (Premium Systems). The appropriate sensor/transmitter can then be replaced. If a single sensor/transmitter cannot be detected by the WCM, replace that sensor transmitter. If none of the sensors/transmitters can be detected, refer to appropriate tests.
