NOTE
1. The OBD II Relearn function is not supported by all vehicles. If the OBD II Relearn
item doesn’t present, that means the sensor’s ID of the vehicle you selected does
not need to be written to the vehicle.
2. The sensor writing procedure may vary for different vehicles being serviced. Please
follow the onscreen instruction and take appropriate measures and selections to
complete the process.
3. If there are untested sensors in the vehicle, the writing ID process cannot proceed.
The tool will display a warning message as below. In this case, follow the sensor
check procedure to activate all sensors in vehicle and register sensor IDs again.

Make sure to turn the ignition off before connecting /disconnecting the OBD II Cable
