10-62 Vehicle Care
The malfunction 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.
The spare tire does not have a
TPMS sensor. The malfunction
light and the DIC message
should go off once you re‐install
the road tire containing the
TPMS sensor and the sensor
matching process is performed
successfully. See "TPMS Sensor
Matching Process" later in this
section.
. The TPMS sensor matching
process was not done or not
completed successfully after
rotating the vehicle's tires. The
malfunction light and the DIC
message should go off once the
TPMS sensor matching process
is performed successfully.
See “TPMS Sensor Matching
Process” later in this section.
. One or more TPMS sensors
are missing or damaged. The
malfunction light and the DIC
message should go off when the
TPMS sensors are installed and
the sensor matching process is
performed successfully. See
your dealer for service.
. Replacement tires or wheels do
not match the vehicle's original
equipment tires or wheels. Tires
and wheels other than those
recommended for the vehicle
could prevent the TPMS from
functioning properly. See Buying
New Tires on page 10‑67.
. 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 for
service if the TPMS malfunction
light and DIC message come on
and stay on.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. Any time you
rotate the vehicle's tires or replace
one or more of the TPMS sensors,
the identification codes will need to
be matched to the new tire/wheel
position. Also, the TPMS sensor
matching process should be
performed after replacing a spare
tire with a road tire containing the
TPMS sensor in order for the
malfunction light and the DIC
message to go off at the next
ignition cycle. 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 for
service.
