a chime. The EVIC will display a “SERVICE TPM SYS-
TEM” message for a minimum of five seconds. This
message is then followed by a graphic display, with - - in
place of the pressure value(s) indicating which TPMS
Sensor(s) 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 “Tire Pressure Monitoring Telltale
Light” will no longer flash, the “SERVICE TPM SYSTEM”
message will not be present, and a pressure value will be
displayed instead of dashes. A system fault can occur by
any of the following scenarios:
• Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.
• Installing some form of aftermarket window tinting
that affects radio wave signals.
• Accumulation of excessive snow and/or ice around
the wheels or wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPMS sensors.
The EVIC will also display a “SERVICE TPM SYSTEM”
message for a minimum of five seconds when a system
fault possibly related to an incorrect sensor location fault
is present. In this case, the “SERVICE TPM SYSTEM”
message is then followed by a graphic display with
pressure values still shown. This indicates that the pres-
sure values are still being received from the TPM sensors
but they may not be in the correct vehicle position. The
system still needs to be serviced as long as the “SERVICE
TPM SYSTEM” message exists.
