the vehicle’s recommended cold placard pressure infla-
tion value as shown in the ⬙Inflate Tire to XX⬙ message.
Once the system receives the updated tire pressures, the
system will automatically update, the graphic display in
the DID will return the pressure values shown to their
original color, and the “TPM Telltale Light” will turn off.
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.
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
DID 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,
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.
