Service TPMS Warning

If a system fault is detected, the TPM Telltale Light will flash on and off for 75 seconds and then remain on solid.

The system fault will also sound a chime. In addition, the EVIC will display a SERVICE TPM SYSTEM message for a minimum of five seconds and then display dashes (- -) in place of the pressure value to indicate which sensor is not being received.

If the ignition switch is cycled, this sequence will repeat,

If the ignition switch is cycled, this sequence will repeat, providing the system fault still exists. If the system fault no longer exists, the TPM Telltale Light will no longer flash, and the SERVICE TPM SYSTEM message will no longer display, and a pressure value will display in place of the dashes. A system fault can occur due to any of the following:

1. Signal interference due to electronic devices or driving next to facilities emitting the same radio frequencies as the TPM sensors.

2. Installing aftermarket window tinting that contains materials that may block radio wave signals.

3. Accumulation of snow or ice around the wheels or wheel housings.

4. Using tire chains on the vehicle.

5. Using wheels/tires not equipped with TPM sensors.

The EVIC will also display a SERVICE TPM SYSTEM message for a minimum of five seconds when a system fault related to an incorrect sensor location fault is detected. In this case, the SERVICE TPM SYSTEM message is then followed with a graphic display with pressure values still shown. This indicates that the pressure values are still being received from the TPM sensors but they may not be located in the correct vehicle position. The system still needs to be serviced as long as the SERVICE TPM SYSTEM message is displayed.

Vehicles With Full Size Spare

1. The matching full size spare wheel and tire assembly has a TPM sensor that can be monitored by the TPMS.

2. If you install the full size spare in place of a road tire that has a pressure below the low-pressure warning limit, upon the next ignition switch cycle, a chime will sound and the TPM Telltale Light will turn ON. In addition, the EVIC will display a low pressure message and a graphic showing the low tire pressure value flashing or in a different color.

3. After driving the vehicle for up to 20 minutes above 15 mph (24 km/h) the TPM Telltale Light will turn OFF, and the pressure value displayed will be updated and stop flashing or return to its original color as long as no tire pressure is below the low-pressure warning limit in any of the four active road tires.

Vehicles With Compact Spare

1. The compact spare tire does not have a TPM sensor.

Therefore, the TPMS will not monitor the pressure in the compact spare tire.

2. If you install the compact spare tire in place of a road tire that has a pressure below the low-pressure warning limit, upon the next ignition switch cycle, the TPM Telltale Light will remain ON and a chime will sound. In addition, the graphic in the EVIC will still display a flashing pressure value or a pressure value in a different color.

3. After driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the TPM Telltale Light will flash on and off for 75 seconds and then remain on solid. In addition, the EVIC will display a SERVICE TPM SYSTEM message for a minimum of five seconds and then display dashes (- -) in place of the pressure value.

4. For each subsequent ignition switch cycle, a chime will sound, the TPM Telltale Light will flash on and off for 75 seconds and then remain on solid, and the EVIC will display a SERVICE TPM SYSTEM message for a minimum of five seconds and then display dashes (- -) in place of the pressure value.

5. Once you repair or replace the original road tire and reinstall it on the vehicle in place of the compact spare, the TPMS will update automatically. In addition, the TPM Telltale Light will turn OFF and the graphic in the EVIC will display a new pressure value instead of dashes (- -), as long as no tire pressure is below the low-pressure warning limit in any of the four active road tires. The vehicle may need to be driven for up to 20 minutes above 15 mph (24 km/h) in order for the TPMS to receive this information.
