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 symptoms in the WCM section. For additional system description and diagnosis, refer to Tire Pressure Monitoring in the Body Diagnostic manual .

TIRE PRESSURE

Check the tire pressure yellow telltale in the instrument cluster. If the yellow telltale is illuminating continuously, adjust the air pressure as necessary to that listed on the Tire Inflation Pressure Label (Placard) provided with the vehicle. After adjusting air pressure in a tire, allow approximately two minutes for the message or yellow telltale to go out. Inspect all the tires for leaks. A water "dunk tank" or other water test may be used as long as any water at the valve core is removed once the procedure is complete. The water can be easily expelled from the core area by pushing in on the core for several seconds, allowing escaping air to drive out any moisture. Reinflate the tire as necessary. Always make sure the original valve stem cap is securely installed to keep moisture out of the sensor. If the yellow telltale is still illuminating continuously or if the yellow telltale is flashing on/off for 60 seconds, once every ten minutes while drive, there is a system fault detected (Refer to 22 - TIRES/WHEELS/TIRE PRESSURE MONITORING - STANDARD PROCEDURE).
