Title: TIRE PRESSURE MONITORING: TIRE PRESSURE WARNING SYSTEM (for HV Model): REGISTRATION; 2023 MY Corolla Corolla HV [09/2022 - 03/2023]

REGISTRATION

PROCEDURE

1. BEFORE REGISTRATION

NOTICE:

The transmitter ID is written on the tire pressure warning valve and transmitter. It is not possible to read the transmitter ID after installing the tire onto the wheel. Therefore, make a note of the transmitter ID before installing the tire.
Tire pressure warning ECU and receiver ID registration after replacement must be performed using the Techstream.
Be sure to check procedures or what work is required after replacing parts.

(a) When replacing tire pressure warning ECU and receiver:

(1) Before replacing, use the Techstream to read and record all of the current IDs and registered tires with transmitters (4 or 5 tires) of the tire pressure warning valve and transmitter registered to the tire pressure warning ECU and receiver.

(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 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)

HINT:

If the ID registration step is not completed within 300 seconds, ID registration will be canceled.

(a) Set the tire pressure to the specified value.

6. REGISTER TRANSMITTER ID (USING AUTOMATIC ID REGISTRATION FUNCTION)

NOTICE:

If the transmitter IDs have not been registered, Vehicle Control History (RoB) X20FA is stored in the tire pressure warning ECU and receiver after 3 minutes or more.
If normal pressure values are displayed, the transmitter IDs have been registered correctly.
If another tire pressure warning valve and transmitter belonging to the same system is installed to a tire other than the one transmitter registration is being performed on, automatic ID registration does not complete.

HINT:

If the ECU Data List is displayed using the Techstream while work is being performed, the registration mode will be canceled.
During the registration process, by selecting the tire set using "Register New Valve / ID" using the multi-information display, registration mode can be canceled.
If the power switch is turned off before driving during the registration procedure, registration mode will continue.

(a) Adjust the tire pressure in all tires to the specified pressure.

Click here

(b) Turn the power 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) Operate the multi-information display and using "Register New Valve / ID", select a tire set to register, and check that 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, and a registration completed message is displayed on the multi-information display.

HINT:

Registration may take longer than normal in the following driving environments.
- Vehicle is often stopped
- Vehicle is stopped for long period of time
- Vehicle is driven in reverse
- Vehicle is driven parallel to another vehicle with the same type of tire pressure warning valve and transmitter installed for a long duration of time
- Vehicle was not stopped for 15 minutes or more before registration
- Vehicle was driven at 40 km/h (25 mph) or less for a long duration of time
- The power switch is turned from on (IG) to off during ID registration

7. TIRE POSITION IDENTIFICATION (NOT USING TECHSTREAM)

(a) Set the tire pressure to the specified value.

Click here

(b) Select "Tire Rotation" on the multi-information display, then drive the vehicle at 40 km/h (25 mph) or more for 10 to 30 minutes in 1 trip until each tire position is automatically identified.

HINT:

When tire position identification is being performed, the tire pressure on the multi-information display is displayed as "---".
Do not drive the vehicle in reverse gear while performing Tire Position Identification. If the vehicle is driven in reverse gear while performing Tire Position Identification, identification information will be discarded and Tire Position Identification may take longer than usual.
When the vehicle is driven under the following conditions, Tire Position Identification may take longer than usual.
- The vehicle is stopped frequently.
- The vehicle is stopped for a long period of time.
- The vehicle is driven in reverse gear.
- The vehicle is driven on rough roads or uneven surfaces.

8. METHOD TO SWITCH ID

NOTICE:

If there is a malfunction in the tire pressure warning system, perform troubleshooting before switching IDs.
To use the ID switching function, a tire and wheel set for which the IDs have already been registered is needed.

(a) Install the tire and wheel set for which the IDs have already been registered.

(b) Turn the power switch on (IG).

(c) Operate the multi-information display and using "Register Valve / ID", select a tire set to register, and check that the tire pressure warning light blinks 3 times.

HINT:
