Depending on the tire pressure sensor position*, a blind spot exists, and the tire pressure receiver gets a poor reception. 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 Nissan Pathfinder vehicle architecture (e.g. body harness layout, tire wheel design) or environment.
When ID registration is performed, which wheels do not react?
All wheels react and ID registration is possible.>>Inspection End.
Only certain wheel(s) do not react.>>Replace applicable tire pressure sensor. Refer to Removal and Installation.
All wheels do not react.>>Replace the BCM. Refer to Removal and Installation.
