Toyota & Lexus TPMS Guide

Toyota TPMS Relearn & ECU ID Programming Guide

Important: All Toyota and Lexus models require the TPMS sensor ECU IDs to be programmed into the vehicle when fitting new sensors. Some models may allow pressure reset or system initialisation through a reset button, but new sensor IDs still need to be registered correctly for proper operation.

Key Requirement

New Toyota and Lexus TPMS sensors must have their sensor IDs written to the ECU using the correct programming method.

Reset Button Note

Not all models have a TPMS reset button. If no button is fitted, a relearn may not be needed after a pressure adjustment or tyre rotation, but new sensor installation still requires ID programming.

Recommended Tool

We highly recommend the AUTOMATE Bluetooth Programmer to ensure proper activation, registration, and successful TPMS setup.

Important Note

About the TPMS Reset Button

Not all Toyota models are fitted with a TPMS reset button.

If no reset button is found, a relearn is generally not required following an air pressure adjustment, tyre rotation, or tyre replacement. However, when installing new TPMS sensors, the sensor IDs still need to be programmed into the ECU.

The reset button is commonly located on the driver’s side knee bolster, inside the glove box, under the steering wheel, or next to the DLC / OBDII port.

Its purpose is to set a new pressure baseline and re-establish communication between the vehicle and the TPMS sensors.

Procedure 01

Initialisation After Rotation or Tyre Replacement

Use this process after rotating tyres or replacing tyres where the existing registered TPMS sensors remain in use.

  1. Inflate all tyres to the pressure shown on the tyre placard.
  2. Turn the ignition to the ON / RUN position with the engine off.
  3. Press and hold the tyre pressure reset button until the TPMS warning light flashes 3 times.
  4. Wait for the ECU to receive signals from all sensors. This may take approximately 2–3 minutes.
  5. If initialisation is not completed, drive the vehicle for approximately 20 minutes.
Reminder: This initialisation step is not the same as programming new ECU IDs. It is mainly used to reset the tyre pressure baseline when existing sensors remain fitted.
Procedure 02

Initialisation After New Sensor Installation

When fitting brand-new TPMS sensors, the new IDs must be registered into the vehicle.

  1. A properly formatted scan tool is required to learn and register the new TPMS sensor IDs.
  2. Write the new TPMS sensor IDs into the ECU via the OBD connection.
  3. Leave the ignition switched ON after the IDs have been registered.
  4. Activate all TPMS sensors using a TPMS activation tool.
  5. Confirm that all sensors communicate correctly and that the warning light clears.
Recommended: We highly recommend using the AUTOMATE Bluetooth Programmer to help ensure a successful sensor activation and setup process.
TIA Troubleshooting Tip

Main / 2nd Switch Information

Many Toyota SUVs and minivans are fitted with a Main / 2nd switch.

What the Switch Does

This switch allows the vehicle to store two sets of TPMS IDs — one for the main wheel set and another for a second seasonal wheel and tyre set.

Main Position

When the switch is not pressed, the system monitors the OEM or main TPMS IDs stored in the vehicle.

2nd Position

When pressed, the vehicle can monitor a second set of sensor IDs, often used for winter or alternate wheel sets.

Common Fault

If the button is pressed but no IDs are stored in the second memory position, the MIL / TPMS warning light may illuminate.

Important Setup Check

Always ensure you are writing the TPMS sensor IDs into the correct memory position when programming the vehicle.

Typical Location

The Main / 2nd switch is commonly located inside or under the glove box or at the base of the driver’s knee bolster.
