Low Tire Warning (LTW) System

WARNING: This page is about a different car, the 2003 Ford Windstar. However, it is still accessible from the selected car via links, so may be relevant.

The Low Tire Warning (LTW) System detects differences in inflation pressures in one or more tires. The system uses the ABS wheel speed sensors to monitor the rolling radius of the wheel and tire assemblies. If a difference in rolling radius is detected, the ABS module illuminates the LTW lamp located in the instrument cluster. The LTW system must be reset when tire replacement, maintenance, system repair is performed or any time tire pressure is adjusted. To reset the system, press and hold the "Tire Reset" switch for a minimum of three seconds. The LTW warning lamp will flash 3 times indicating a reset has been initiated.

If the lamp illuminates always reset the tire pressure to specification before resetting the system. If the problem persists, go to SYMPTOM CHART . For additional information, refer to WHEELS & TIRES .

The LTW system is not capable of detecting rapid loss of inflation. The system may not detect loss of inflation in more than one tire.

The LTW system can be deactivated. For additional information regarding deactivation, refer to INSTRUMENT CLUSTER .
