5. Turn on the TPMS tool by pressing the green selectbutton. Press the green select button until the
proper light sequence is illuminated as per the tool
user’s manual.
6. Follow the prompts on the HDS to activate the tire pressure sensors using the TPMS tool.
NOTE: See the HDS Help menu for specific
instructions. 7. Check the HDS screen, and note the active sensor
reception order of tire pressure sensor 1, 2, 3, 4.
NOTE: If the sensor does not respond to the TPMS tool, make sure the tool was turned on properly. Refer
to the HDS.
If the tool start mode is OK, then rotate the tire 1/4 turn and retry.
If the sensor still does not respond after one full rotation of the tire, then check for DTC 32, 34, 36,
and38withtheHDS.
8. Turn the ignition switch to LOCK (0).

Once the vehicle speed exceeds 45 km/h (28 mph), the TPMS control unit monitors all four tire pressure sensors and
the system function. If it detects low pressure in a tire, it alerts the driver by turning on the low tire pressure indicator.
If it detects a problem in the system, it turns on the TPMS indicator.
Mounted inside of the dash, the TPMS control unit receives wireless pressure sensor ID signals
every time the vehicle
speeds exceeds 45 km/h (28 mph). It also receives wireless signals from the transmitters for tire pressure and the
sensor condition, and it continuously monitors and controls the system. The TPMS control unit cannot directly
determine the position (location) of a tire pressure sensor(s) on the vehicle since it is a wireless system. TPMS sensor
locations will change during scheduled vehicle maintenance (tire rotation).
NOTE: To determine the actual location of each TPMS wheel sensor on the vehicle, do the tire pressure sensor
location procedure (see page 18-53). Once the tire pressure sensor locations are identified, write the sensor ID on the
side wall of the tire with a tire crayon to eliminate confusion.
Two indicators are in the gauge control module (tach): The low tire pressure indicator comes on when any tire
pressure is low, and the TPMS indicator that comes on only if there’s a problem with the system.
The low tire pressure indicator alerts the driver that a tire(s) pressure is low, but does not specify the tire(s) location.

Each sensor is an integrated unit made up of the tire valve stem, a tire pressure sensor, and a transmitter. The unit is
attached to the inside of the wheel, around the valve stem. The sensor transmits the internal tire information to the
control unit once every 60 seconds when the vehicle speed exceeds 45 km/h (28 mph). When the TPMS control unit
receives a tire pressure signal that is less than 175 kPa (1.8 kgf/cm , 25 psi) with 16 inch wheels, or 183 kPa (1.9 kgf/cm ,
27 psi) with 17 inch wheels, the TPMS control unit then turns on the low tire pressure indicator. When that tire’s
pressure is increased to more than 200 kPa (2.0 kgf/cm , 29 psi) with 16 inch wheels, or 210 kPa (2.1 kgf/cm , 30 psi)
with 17 inch wheels, and the vehicle is driven above 45 km/h (28 mph) the transmitter sends the tire pressure signal to
the control unit, and then the control unit turns the indicator off.
NOTE: Do not mix the TPMS tire pressure sensors or wheels with other TPMS types. Be sure to use the correct type
sensors and wheels for this system.
Sensor are active:
When the wheel rotates over 45 km/h (28 mph), the sensor detects the momentum, switches the sensor to the normal function mode.
The LF (low frequency) signal of the TPMS tool makes the sensor active even t hough the vehicle is stopped. The tire
pressure sensor goes into sleep mode when the acceleration sensor detects the wheel is stationary for 5 minutes or
more continuously.
The TPMS will not work unless TPMS type wheels are installed on the vehicle. There are three different types of
wheels used. The original equipment wheels have a ‘‘TPMS’’ mark (A) on them and are counterweighted (B) the
opposite of the tire pressure sensor (C), and counterbalance the weight of the sensor.
