LEXUS TPMS SENSORS, INITIALISATION & PROGRAMMING GUIDE
Replacing Lexus TPMS sensors is not always as simple as fitting the hardware and driving away. In many cases, a Lexus can be initialised after a tyre pressure adjustment, tyre rotation, or tyre replacement. But when new TPMS sensors are installed, the new sensor IDs usually need to be programmed into the ECU.
We strongly recommend the AUTOMATE Bluetooth Programmer to help ensure successful activation and a smoother Lexus TPMS installation.

Reset vs New Sensor Programming
Not all Lexus models have a TPMS reset button. If there is no reset button, a relearn is generally not required after an air pressure adjustment, tyre rotation, or tyre replacement. But new sensor installation is different — new sensor IDs often need to be programmed into the ECU.
Where the Reset Button Is
If fitted, the Lexus TPMS reset button is commonly found on the driver’s knee bolster, inside the glove box, under the steering wheel, or next to the DLC / OBDII port.
Best Way to Avoid Problems
We highly recommend purchasing the AUTOMATE Bluetooth Programmer so the new sensors can be activated correctly and the installation has a much better chance of succeeding the first time.

After Rotation or Tyre Replacement
Use this process after tyre rotation or tyre replacement where the existing registered sensors remain in use.
Important: Not all models come equipped with a TPMS reset button. If no button is found, then a relearn is generally not required following an air pressure adjustment, tyre rotation, or tyre replacement.
The purpose of the reset button is to set a new baseline for the air pressure and re-establish communication between the sensors and the vehicle.
- Inflate all tyres to the pressure listed on the tyre placard.
- Turn ignition to the ON / RUN position with the engine off.
- Hold down the tyre pressure reset button until the TPMS warning light flashes 3 times.
- Initialisation will be completed when the ECU has received signals from all sensors. This may take approximately 2–3 minutes.
- If initialisation is not complete, drive the vehicle for approximately 20 minutes.
Why You Need a Proper Tool
When replacing Lexus TPMS sensors with brand-new sensors, a properly formatted scan tool is required to learn the new sensor IDs. After the IDs have been registered via the OBD, ignition must remain on and all sensors should be activated using a TPMS activation tool.
- New TPMS sensor IDs often need to be written to the Lexus ECU
- Simply fitting the sensors is usually not enough
- Activation after OBD registration is still required
- The wrong tool or incomplete setup can leave the warning light on
- The safest way to avoid repeat work is to use the right TPMS tool from the start
