Toyota Prius: Tire Pressure Warning Receiver
Registration
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 GTS.
-
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 GTS 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. |
|
2. REGISTER TRANSMITTER ID (USING GTS)
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.
Click here
(b) On the GTS screen, display "ID Registration/Tire Number Registration" of Utility.

- 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 ignition switch to ON.
| (c) Using the steering pad switch assembly, select "Tire Set Switching" and then "Register Valve / ID" on the multi-information display and check that the tire pressure warning light blinks 3 times. HINT: When the switch ID procedure is being performed, the tire pressure warning light blinks for 1 minute before turning on and the tire pressure on the multi-information display is displayed as "---". |
|
(d) Stop the Toyota Prius vehicle and wait for 2 minutes.
NOTICE:
Do not drive the vehicle during the ID switching procedure. Driving the vehicle will cause it to change to the automatic ID registration mode.

Initialization
INITIALIZATION
NOTICE:
- Initialization can be confirmed through the tire pressure warning light.
- If the ignition switch is turned off during initialization, the tire pressure warning ECU and receiver memorizes that initialization was being performed. Therefore, it is not necessary to perform the initialization procedure again after turning the ignition switch to ON. (Only when "Setting by Current Pressure" is selected.)
- The order in which the data is received is random. (Only when "Setting by Current Pressure" is selected.)
- If the signals from all the tire pressure warning valve and transmitters are received, initialization is completed. (Only when "Setting by Current Pressure" is selected.)
-
When "Complete" is displayed for the value of Data List item "Initialization Not Completed", the initialization is completed.
Click here
- Initialization is normally completed within a few minutes. (Only when "Setting by Current Pressure" is selected.)
- If initialization has not been completed successfully, Toyota Prius Vehicle Control History (RoB) X20FE is stored after a vehicle speed of 40 km/h (25 mph) or more continues for 20 minutes or more. (Only when "Setting by Current Pressure" is selected.)
- Even if initialization is performed, the existing tire positions will not be cleared. Perform the tire position identification procedure as necessary.
BEFORE INITIALIZATION
(a) Set the tire pressure to the specified value. (Only when "Setting by Current Pressure" is selected.)
NOTICE:
Refer to the link as the procedure for adjusting the tire pressures differs depending on the temperature of the tires.
Click here
INITIALIZATION PROCEDURE
HINT:
The tire pressure warning system illuminates the tire pressure warning light to warn the driver when any of the following conditions are met:
- The tire pressure drops to approximately 75% or less of the tire pressure set when system initialization was performed using the steering pad switch assembly.
-
The tire pressure drastically decreases (approximately 20 kPa (0.2 kgf/cm2, 2.9 psi) or more within several minutes) to approximately 75% or less of the tire pressure* when the tires are warmed.
*: If initialization is performed and the Toyota Prius vehicle is driven for a certain period of time, the tire pressure set during system initialization is adjusted and set to the tire pressure when the tires are warmed from the driving conditions.
NOTICE:
If the tire pressure is decreased approximately 20 kPa (0.2 kgf/cm2, 2.9 psi) or more in order to adjust the tire pressure, even if the adjusted tire pressure is 75% or more than the tire pressure set during system initialization, the tire pressure warning light may illuminate if the tire pressure drops below 75% of the tire pressure set when the tires are warmed. In this case, perform initialization again.
(a) Using the steering pad switch assembly, select "Tire Pressure Setting" and then "Setting by indicated air pressure" or "Setting by Current Pressure" on the multi-information display and check that the tire pressure warning light blinks 3 times.
