TPMS: 2019 Toyota Rav4

FUNCTION & PRECAUTIONS

The tire pressure monitoring system (TPMS) may be disabled under the following conditions. When the condition returns to normal, the system will work properly.

• When electric devices or facilities using similar radio frequencies are nearby.
• When a wireless device or other equipment operating at a similar frequency is in use in the vehicle.
• When a window tint that affects radio wave signals is installed.
• When there is a lot of snow or ice on the vehicle, particularly around the wheels or wheel housing.
• When non-genuine wheels are used.
• When tire chains are used.
• When aftermarket tire repair sealant is used. (After use of tire repair sealant, replacement of the tire pressure warning valve and transmitter is required to ensure normal system operation. Normal system operation cannot be ensured by only repairing or replacing the tire.

The tire inflation pressure display function displays the position and pressure of each tire on the multi-information display. If the position and pressure of each tire is not displayed, the problem may be alleviated by driving the vehicle to a location where the signal reception is better.

Procedures when replacing parts:

1. When replacing the tire pressure warning valve, transmitter, tire pressure warning ECU and receiver, perform ID registration for the tire pressure warning valve and transmitter.
2. After performing ID registration for the tire pressure warning valve and transmitter, make sure to initialize the tire pressure warning system.
3. After performing ID registration for the tire pressure warning valve and transmitter and initializing the tire pressure warning system, perform tire position identification.

TPMS REGISTRATION

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.

Make sure to perform ID registration using the Techstream after replacing the tire pressure warning ECU and receiver.

Before registration

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.

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.

When replacing a tire pressure warning valve and transmitter: Make a note of the 7-digit number (transmitter ID) written on the tire pressure warning valve and transmitter.

Register transmitter ID (using Techstream)

The previously registered IDs will be cleared from memory when registration is completed. If the ID registration step is not completed within 300 seconds, ID registration will be canceled.

1. Set the tire pressure to the specified value.
2. Turn the ignition switch off.
3. Connect the Techstream to the DLC3.
4. Turn the ignition switch to ON.
5. Turn the Techstream on.
6. Enter the following menus: Chassis/Tire Pressure Monitor/Utility/ID Registration/Tire Number Registration.
7. Perform the procedure displayed on the Techstream.

The number of registered tire pressure warning valve and transmitters can only be set to four when the value is currently set to five. The number of registered tire pressure warning valve and transmitters should only be changed from the default value when requested by the customer.

After all transmitter IDs are registered, DTC C2126 is stored in the tire pressure warning ECU and receiver and the tire pressure warning light blinks for one minute and then illuminates. When the tire pressure warning ECU and receiver successfully receives signals from all the transmitters whose IDs are stored in the ECU, DTC C2126 is cleared and the tire pressure warning light goes off.

Confirmation of registration (using Techstream)

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

It may take a few minutes until the values are displayed. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121 to C2124.

1. Reduce the tire inflation pressure of each tire by 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.
2. 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.

During registration, DTC C2128 is stored by the tire pressure warning ECU and receiver and the tire pressure warning light blinks for one minute then illuminates. When the tire pressure warning ECU and receiver successfully receives signals from all the transmitters whose IDs are stored in the ECU, DTC C2128 is cleared and the tire pressure warning light turns off.

Register transmitter ID

When registration is complete, all previously registered IDs are cleared. If DTCs C2176, C2179 and U0129 are stored, registration mode cannot be entered.

If the Techstream is being used to display the Data List, registration mode cannot be entered. If it is used to display the Data List during registration, registration will be canceled.

If DTCs C2176, C2179 and U0129 are stored during registration, registration will be canceled.

If the ignition switch is turned off before the vehicle is driven after entering registration mode, registration will be canceled.

1. Adjust the tire pressure in all tires to the specified pressure.
2. Turn the ignition switch off and stop the vehicle for 15 minutes or more. (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 to eight times the normal frequency for the first few minutes of driving.
3. Select "Change Wheel" on the multi-information display and press and hold the "OK" switch (steering pad switch assembly) until the tire pressure warning light blinks three times.

During registration, the tire pressure warning light blinks for one minute before turning on, the multi-information display tire pressure displays as "- - -" and "Tire Pressure Recalibrating Please Wait until Complete" is displayed.

4. Drive at approximately 25 mph for approximately 10 to 30 minutes during one trip. While driving, also make two or more right or left turns.

5. 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.

Registration may take longer than normal in these situations.

• The vehicle is stopped frequently or for a long period of time.
• The vehicle is driven in reverse.
• The vehicle is driven on rough roads or uneven surfaces
• The vehicle is driven in close proximity to another vehicle for a long period of time with the same type of tire pressure warning valve and transmitter installed.
• The vehicle was not stopped for 15 minutes or more before registration.
• The vehicle is driven at 25 mph or less for a long period of time.
• The ignition switch is turned off during ID registration.
