TPMS Malfunction Light and
Message
The TPMS will not function properly
if one or more of the TPMS sensors
are missing or inoperable. When the
system detects a malfunction, the
low tire warning light flashes for
about one minute and then stays on
for the remainder of the ignition
cycle. A DIC warning message is
also displayed. The low tire warning
light and DIC warning message
come on at each ignition cycle until
the problem is corrected. Some of
the conditions that can cause the
malfunction light and DIC message
to come on are:
.
One of the road tires has been
replaced with the spare tire,
if the vehicle has one. The spare
tire does not have a TPMS
sensor. The DIC message
should go off once you re-install
the road tire containing the
TPMS sensor.
.
The TPMS sensor matching
process was not done or not
completed successfully after
rotating the vehicle's tires.
The DIC message should go off
after successfully completing
the sensor matching process.
See “TPMS Sensor Matching
Process” later in this section.
.
One or more TPMS sensors are
missing or damaged. The DIC
message and the TPMS
malfunction light should go off
when the TPMS sensors are
installed and the sensor
matching process is performed
successfully. See your dealer/
retailer for service.
.
Replacement tires or wheels do
not match your vehicle's original
equipment tires or wheels.
Tires and wheels other than
those recommended for your
vehicle could prevent the TPMS
from functioning properly. See
Buying New Tires on page 9‑75.
.
Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning it
cannot detect or signal a low tire
condition. See your dealer/retailer
for service if the TPMS malfunction
light and DIC message comes on
and stays on.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. Any time you
replace one or more of the TPMS
sensors or rotate your vehicle's
tires, the identification codes need
to be matched to the new tire/wheel
position. The sensors are matched
to the tire/wheel positions in the
following order: driver side front tire,
passenger side front tire, passenger
side rear tire, and driver side rear
tire using a TPMS diagnostic tool.
See your dealer/retailer for service.
