Sensor Registration

NOTE: This procedure relies on the use of the Toyota Intelligent Tester or Techstream.

NOTE: It is necessary to register the transmitter ID in the tire pressure warning ECU when replacing the tire pressure warning valve and transmitter and/or tire pressure warning ECU. Before registration:

In case of tire pressure warning ECU replacement.
- Read the registered transmitter IDs that are stored in the old ECU using the Intelligent Tester and note them down.
- If reading stored transmitter IDs is impossible due to malfunctions of components such as the tire pressure warning antenna and receiver, remove the tires from the wheels and check the IDs located on the tire pressure warning valves and transmitters.
In case of tire pressure warning valve and transmitter replacement.
- When replacing the tire pressure warning valves and transmitters, note down the IDs written on the tire pressure warning valves and transmitters.

Connect the Intelligent Tester to DLC3.
Turn the engine switch ON.
Turn the Intelligent Tester ON and enter the menu items in this order: DIAGNOSIS / OBD/MOBD / CHASSIS / TIRE PRESSURE. Then, select the "UTILITY" item.
Select the registration mode "MAIN".

NOTE:

Check that tire pressure warning select switch is "MAIN".
When registering 2nd set, select the registration mode "2nd" after changing tire pressure warning select switch to "2nd".

Input the IDs (ID1 to ID4 or ID5) using the Intelligent Tester and transmit them to the tire pressure warning ECU.
The "ID Registration is complete" is displayed.
NOTE:
- The tire pressure warning light will continue to blink until the tire pressure warning ECU receives the input ID signals.
- Registration can be performed during initialization. However, the initialization will be cancelled when the registration is started.
