System Fault

If a system fault is detected, a chime will sound, and the TPM indicator (telltale) lamp will flash for 75 seconds, then remain on solid. For vehicles with the Premium TPM Systems, a "SERVICE TIRE PRESSURE MONITORING SYSTEM" message will appear in the Electronic Vehicle Information Center (EVIC), followed by a graphic display. A system fault can occur by many scenarios, including the following:

• Signal interference due to electronic devices or driving next to facilities emitting the same Radio Frequencies as the TPM sensors.
• Installing some form of aftermarket window tinting that affects radio wave signals.
• Accumulation of snow or ice around the wheels or wheel housings.
• Using tire chains on the vehicle.
• Using wheels not equipped with TPM sensors.

Refer to the appropriate diagnostic information.
