TPMS Sensor Identification Codes
Each TPMS sensor has a unique identification
code. Any time you replace one or more of
the TPMS sensors, install the spare tire onto your
vehicle, or rotate your vehicle’s tires, the
identification codes will need to be matched to the
new tire/wheel position. The sensors are
matched to the tire/wheel positions in the following
order: driver’s side front tire, passenger’s side
front tire, passenger’s side rear tire, and driver’s
side rear tire using a TPMS diagnostic tool.
See your dealer for service.
The TPMS sensors may also be matched to each
tire/wheel position by increasing or decreasing
the tire’s air pressure. If increasing the tire’s
air pressure, do not exceed the maximum inflation
pressure indicated on the tire’s sidewall.
You will have one minute to match the first
tire/wheel position, and five minutes overall, to
match all four tire/wheel positions.
If it takes longer than one minute, to match the
first tire and wheel, or more than five minutes
to match all four tire and wheel positions
the matching process stops and you will need to
start over.
The TPMS sensor matching procedure is
outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON with the
engine off.
3. Turn the exterior lamp switch from AUTO to
ON four times within three seconds. A double
horn chirp will sound and the TPMS low
tire warning light will begin to flash. The
double horn chirp and flashing TPMS warning
light indicates the TPMS matching process
has started. The TPMS warning light should
continue flashing throughout the matching
procedure. The SERV TPM message will be
displayed on the Driver Information
Center (DIC).
4. Start with the driver’s side front tire.
