TPMS RESET - PROCEDURE 5

Tire Pressure Sensor Registration

NOTE:

When a tire, wheel, tire pressure sensor and/or tire pressure monitor ECU are
replaced, the sensor ID must be memorized by the tire pressure monitor ECU.
See TIRE PRESSURE SENSOR REGISTRATION.

NOTE:

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

Register Transmitter ID

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

information label.

2. Turn ignition switch OFF.

3. Connect a Techstream to the DLC3.

4. Turn ignition switch ON.

5. Turn Techstream ON.

6. Enter the following menus: Chassis / Tire Pressure Monitor / Utility / ID Registration.

NOTE:

It is necessary to register the transmitter ID in the tire pressure warning ECU
when replacing the tire pressure warning valve, transmitter and/or tire pressure
warning ECU. The transmitter ID is written on the tire pressure warning valve
and transmitter. You will not be able to read the ID numbers after installing the
tire pressure warning valve and transmitter on the tire and wheel. Take a note of
the 7 digit number (transmitter ID) written on the tire pressure warning valve
and transmitter before starting registration. See Fig. 15

7. Follow the procedures displayed on the screen.

8. Confirm the ID numbers for all tires (including the spare tire) are displayed on the screen.

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 a Techstream to the DLC3.

3. Turn ignition switch ON.

4. Turn Techstream ON.

5. Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

6. Observe the "ID Tire Inflation Pressure" values.

7. Confirm the ID numbers for all tires (including the spare tire) are displayed on the screen. If all values are

displayed correctly, registration was completed successfully.

TPMS RESET - PROCEDURE 6

NOTE:



It may take up to 2 or 3 minutes to update the tire pressure data. If the
values are not displayed after a few minutes, see the appropriate
manufacturer service information.



If the IDs have not been registered, DTC C2171/71 is set in the tire
pressure warning ECU after 3 minutes or more.



If normal pressure values are displayed, the IDs have been registered
correctly.



If the tire pressure values are not displayed after a few minutes, the IDs
may be incorrect or the system may have a malfunction.



After all IDs are registered, DTC C2126/26 (Transmitter ID not Received in
Main Mode) is set in the tire pressure warning ECU and the tire pressure
warning light blinks for 1 minute and then stays on. When the tire pressure
warning ECU successfully receives radio waves from all the transmitters
whose IDs are stored in the ECU, DTC C2126/26 is deleted and the tire
pressure warning light goes off.

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 system
after the terminal is reconnected: moon roof. Refer to owner's manual or
appropriate manufacturer service information.

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.

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.) 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 7

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
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:

The system will need to be initialized when tires are rotated; tires are replaced
with tires of different pressures; tire pressure sensor and/or tire pressure
monitor ECU are replaced; or when a new vehicle is delivered. Set tire pressure
within the specified range before initializing. If tire pressure sensor and/or tire
pressure monitor ECU were replaced, ensure that tire pressure sensor IDs are
registered prior to initialization. Refer to owner's manual or appropriate
manufacturer service information.
