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 tyre pressure warning light
flashes for about one minute and
then stays on for the remainder of
the ignition cycle. A DIC warning
message also displays. 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 these to come on are:
.
One of the road tyres has been
replaced with the spare tyre. The
spare tyre does not have a
TPMS sensor. The malfunction
light and the DIC message
should go off after the road tyre
is replaced 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 tyres. The
malfunction light and 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
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 tyres or wheels do
not match the original equipment
tyres or wheels. Tyres and
wheels other than those
recommended could prevent the
TPMS from functioning properly.
See
Buying New Tyres on
page 10-51
.
.
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
properly, it cannot detect or signal a
low tyre 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. The identification
code needs to be matched to a new
tyre/wheel position after rotating the
vehicle's tyres or replacing one or
more of the TPMS sensors. Also,
the TPMS sensor matching process
should be performed after replacing
a spare tyre with a road tyre
containing the TPMS sensor. The
malfunction light and the DIC
message should go off at the next
ignition cycle. The sensors are
matched to the tyre/wheel positions,
