If an ID registration is performed under this condition, the registration may not be completed. In such case, follow the instructions below to improve the radio wave receiving environment.
Rotate tire by 90°, 180°, or 270°. (This step is to change tire pressure sensor position.)
Open the door close to the tire of which ID registration is ongoing.
*: Radio wave reception condition depends on vehicle architecture (e.g. body harness layout, tire wheel design) or environment.
