REGISTRATION
PROCEDURE
1. BEFORE REGISTRATION
NOTICE:
(a) When replacing the tire pressure warning ECU and receiver:
(1) When replacing the tire pressure warning ECU and receiver, read the transmitter IDs and number of the transmitters (4 or 5) stored in the old ECU using the Techstream and write them down before removal.
(2) If reading the stored transmitter IDs is impossible due to malfunctions of components such as the tire pressure warning ECU and receiver, remove the tires from the wheels and check the IDs located on the tire pressure warning valve and transmitters.
(b) When replacing a tire pressure warning valve and transmitter:
(1) Take a note of the 7-digit number (transmitter ID) written on the tire pressure warning valve and transmitter.
*1 | Tire Pressure Warning Valve and Transmitter | - | - |
*a | Transmitter ID (7-digit Number) | - | - |
2. REGISTER TRANSMITTER ID (USING TECHSTREAM)

ID 4 Tire Inflation Pressure |
(b) Reduce the tire inflation pressure of each tire 40 kPa (0.4 kgf/cm2, 5.8 psi) or more, and check that the "ID Tire Inflation Pressure" data is updated and that the actual tire inflation pressures are displayed.
(c) After confirming that all of the tire inflation pressure values (except the compact spare tire) have been updated, adjust the tire inflation pressure to the specified value, operate the steering pad switch assembly and perform initialization.
4. REGISTER TRANSMITTER ID (USING AUTOMATIC ID REGISTRATION FUNCTION)
NOTICE:
HINT:
(a) Adjust the tire pressure in all tires to the specified pressure.
(b) Turn the engine switch off and stop the vehicle for 15 minutes or more.
HINT:
After stopping the vehicle for 15 minutes or more, the frequency of electrical wave signals sent by the tire pressure warning valve and transmitters increases for the first few minutes of driving (8 times the normal frequency).
(c) Select "Change Wheel Set" on the multi-information display and press and hold the "OK" switch (steering pad switch assembly) until the tire pressure warning light blinks 3 times.
HINT:
During registration, the tire pressure warning light blinks for 1 minute before turning on, the multi-information display tire pressure displays as "- -" and "Tire Pressure Recalibrating Please Wait until Complete" is displayed.
(d) Drive at approximately 40 km/h (25 mph) for approximately 10 to 30 minutes during 1 trip.
(e) During the procedure, make 2 or more right or left turns.
HINT:
Do not drive the vehicle in reverse during registration.
If the vehicle is driven in reverse during registration, the information may be reset before registration completes, and registration may take longer than normal to complete.
(f) When registration is completed, the tire pressure warning light turns off, the normal tire pressure is displayed on the multi-information display and "Tire Pressure Recalibrating Please Wait until Complete" stops displaying.
