TPMS relearning is a crucial process for ensuring the proper functioning of your vehicle's Tire Pressure Monitoring System (TPMS). This procedure is aimed at re-establishing communication between the car's sensors and the TPMS module, ultimately maintaining the normal operation of the vehicle.

Each TPMS sensor on the wheels is assigned a unique ID, and these sensor IDs are registered in the vehicle's TPMS module, corresponding to their respective wheel positions. When you replace a sensor or rotate the tires, it becomes necessary to register a new sensor ID or relearn the existing one for the specific wheel location on the vehicle.

The primary function of TPMS is to provide drivers with real-time information about the tire pressure status in their vehicle's wheels. TPMS relearning, or reset, is essential to prevent any error notifications on the automotive ECU after routine maintenance or repairs, such as tire changes.


Different methods can be employed for TPMS sensor relearning, depending on the vehicle's make and model. Here are some common relearning methods:

Automatic Relearning: This method involves driving the vehicle at a specific time and speed to enable the relearning process.

OBD Relearning: In this approach, a TPMS tool is connected to the vehicle's OBD (On-Board Diagnostics) port to write or relearn the sensor ID into the vehicle's ECU. This method is frequently used in Japanese and Korean manufactured vehicles, as well as in certain models from Chrysler, Fiat, Land Rover, and Jaguar.

Fixed Relearn: This method allows the vehicle to relearn a new sensor ID without driving the vehicle or writing the ID into the TPMS module. The relearning process is typically performed while the vehicle is in Park mode. This method is more commonly used in some Chinese and Japanese-made cars, including General Motors, Ford, Nissan, and others.

To access the fixed relearn mode, you need to follow these steps:

Utilize the OBD function of an Autel TPMS tool to enable Training or Relearn mode.

Follow the instructions provided by the Autel tool to operate the onboard buttons. Afterward, activate all tire pressure sensors in a specific sequence, often starting clockwise, commencing with the left front wheel, and concluding with the left rear wheel.

Autel offers a TPMS relearning tool called TS508WF that can help you with this process. It simplifies the relearning procedure and ensures that your vehicle's TPMS functions properly.

TPMS relearning is essential for maintaining the accurate monitoring of tire pressure in your vehicle. Depending on your vehicle's make and model, you can choose the appropriate relearning method to ensure that the TPMS continues to work effectively, preventing error notifications on your vehicle's ECU. Autel's TS508WF TPMS relearning tool is a reliable solution to assist in this process.
