The TPMS Warning Light will flash on and off for 75
seconds, and will remain on solid when a system fault is
detected. The system fault will also sound a chime. If the
ignition key is cycled, this sequence will repeat, providing
the system fault still exists. The TPMS Warning Light will
turn off when the fault condition no longer exists. A system
fault can occur by any of the following scenarios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the
TPM sensors.
2. Installing some form of aftermarket window tinting that
affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel hous-
ings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
Vehicles not equipped with instrument cluster display will
inform the driver which tire(s) are low but not provide
actual tire pressure. The low tire ISO telltale will illuminate
along with “LoTIrE” message displayed in the ODO and
then it will scroll to which tire location is lower than the
Placard Value.
Tire location will be displayed as follows:
LF = Left Front
rF = right Front
Lr = Left rear
rr = right rear
