Confirmation Of Transmitter ID Registration

1. Set the pressure of all tires (including spare tire) to the pressure specified on the tire and loading

information label.

2. Connect the hand-held tester to DLC3.

3. Turn ignition switch to ON position.

4. Select the "TIRE PRESS" by following the prompts on the hand-held tester.

5. Confirm accurately registered tire pressures for all tires. If all values are displayed correctly, registration

was completed successfully.

TPMS RESET - PROCEDURE 2

Initializing Tire Pressure Monitor System

1. Set the tire pressure of all wheels to pressure specified on the tire and loading information label.

2. With vehicle stopped and parking brake applied, turn ignition switch to ON position.

3. Press and hold the tire pressure warning reset switch until the tire pressure warning light blinks 3 times at

one-second intervals.

NOTE:

It may take 2 - 3 minutes to update the tire pressure data. If ID registration
has not occurred, DTC 2171/71 will be recorded in the ECU after 51
minutes or more.

NOTE:

This system requires initializing after changing tires or wheels, after rotating the
tires, or when tire pressure warning light blinks twice every second. Set tire
pressure within the specified range before initializing. If the tire air pressure is
not within the specified range, tire pressure warning system will not function.
See INITIALIZING TIRE PRESSURE MONITOR SYSTEM.

NOTE:

If the negative battery terminal is disconnected, initialize the following systems
after the terminal is reconnected: power window and sliding roof. Refer to
owner's manual or appropriate manufacturer service information.

CAUTION: DO NOT push the reset switch without adjusting tire inflation pressure.

Otherwise, the low tire pressure warning light may not come on even if the
tire pressure is low, or it may come on when the tire inflation pressure is
actually normal. If you push the reset switch while the vehicle is moving,
initialization is not performed.

NOTE:

If the tire pressure warning light does not blink, turn ignition switch to OFF
position and perform the initialization procedure again starting at step 2. If
light still does not blink, there is a problem in the TPM system. See

4. Drive the vehicle at 19 MPH (30 KM/H) or more to complete the initialization of the skid control ECU (it

takes 0.5-1 hour). Vehicle should be driven under the following conditions:



The vehicle speed is between 31-62 MPH (50-100 KM/H).



The roads are dry, smooth and straight.



The number of passengers is 1 or 2 (including driver).

5. After initialization is completed, the skid control ECU monitors the tire pressure by using the wheel speed

sensors.

6. To verify the system has been initialized, check the length of time the tire pressure warning light is on

after turning the ignition switch to the ON position. Light will stay on for 3 seconds if system is
initialized, or 4 seconds if system is not initialized.

TPMS RESET - PROCEDURE 3

1. Park vehicle in a safe place and turn ignition key to LOCK position.

2. Adjust the pressure of all installed tires to specified cold tire inflation pressure level.

3. Turn ignition to ON position.

4. Push and hold tire pressure warning reset switch (located below left side of dash) until the tire pressure

warning light blinks slowly 3 times.

5. Leave system for a few minutes with ignition switch in ON position, and then turn ignition key to LOCK

position.

If the tire warning reset switch is pushed while vehicle is moving, initialization will not take place. If reset
switch is accidentally pushed, and initialization takes place, adjust tire inflation pressure to the specified level
and initialize the system again.

If tire pressure warning light does not blink slowly 3 times when you push and hold the reset switch,
initialization has failed and tire pressure warning system may not work properly. In this case, initialize the
system again. If initialization cannot be performed, have the system checked at an authorized dealer.

appropriate manufacturer service information.

NOTE:

If the tire pressure warning light blinks at 0.25 second intervals while the
vehicle is being driven, the initialization may have failed. If so, turn ignition
switch to OFF position and perform the initialization procedure again
starting at step 1.

NOTE:

Initialization is required when changing tire size, rotating tire on vehicle with
different front and rear tire inflation pressures.

NOTE:

This system requires initializing after changing tires or wheels, after rotating the
tires, or when tire pressure warning light blinks once every 3 seconds. Set tire

4. Drive the vehicle at 19 MPH (30 KM/H) or more to complete the initialization of the skid control ECU (it

takes more than one hour). See Fig. 14. Vehicle should be driven under the following conditions:



The vehicle speed is between 31-62 MPH (50-100 KM/H).

CAUTION: DO NOT push the reset switch without adjusting tire inflation pressure.

Otherwise, the low tire pressure warning light may not come on even if the
tire pressure is low, or it may come on when the tire inflation pressure is

appropriate manufacturer service information.

NOTE:

If the tire pressure warning light repeats a cycle of ON (0.5 second) and
OFF (2.5 seconds) while the vehicle is being driven, initialization may have
failed. If so, turn ignition switch to OFF position and perform the
initialization procedure again starting at step 1.
