A Tire Pressure Monitoring System (TPMS) warns the driver when tire pressure falls below the system’s warning threshold. A direct system uses pressure sensors mounted on the wheels, usually inside the tires, to transmit readings wirelessly to a vehicle receiver. Some systems also report temperature.

The warning threshold and information displayed depend on the vehicle; they are not identical for every model. TPMS supports tire safety, but it does not replace regular checks with an accurate pressure gauge or inspection for damage. Follow the tire placard and vehicle owner’s manual.

A TPMS relearn procedure is the process of teaching your vehicle's tyre pressure monitoring system to recognise the unique IDs of new or repositioned sensors. 

Depending on the vehicle, this may happen automatically while driving, through an OBD-II programming tool, by manual registration in the dashboard menu, or by cloning the original sensor IDs onto new sensors.

Follow the vehicle-specific instructions in our TPMS90 Relearn menu, or ask us to confirm the procedure.

Cloning copies the unique ID of an existing sensor onto a new TS01 sensor. The vehicle still sees the same ID, so no relearn is required. Cloning is ideal for second wheel sets, seasonal tire changes, and track wheels.

Cloning does not eliminate the physical fitting of an internal sensor. Have that work completed with appropriate tire-service equipment, and follow the vehicle-specific checks afterward.

Select your vehicle in the TPMS90 menu, then check the relevant manufacturer relearn method. It will show you the exact relearn method — auto, stationary, OBD or clone.

It depends on the vehicle. Auto-relearn vehicles — including many Toyota, Hyundai and Kia models — relearn sensor IDs after a short drive. Other vehicles — most European brands, Tesla, RAM and some other American brands  — require an OBD TPMS tool to write new sensor IDs into the vehicle's ECU before the warning light will switch off.
