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. The spare tire does not have a TPMS
sensor. The TPMS malfunction light and DIC
message should go off once you re-install the
road tire containing the TPMS sensor.
•
The TPMS sensor matching process was started
but not completed or not completed successfully
after rotating the vehicle’s tires. The DIC message
and TPMS malfunction light 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 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 5-69.
•
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.
