ID Registration Cannot Be Completed

ID REGISTRATION CANNOT BE COMPLETED

Description

The ID of the tire pressure sensor installed in each wheel cannot be registered in the tire pressure monitoring system. Inspect the tire pressure sensor or the tire pressure monitoring system circuit.


Diagnosis Procedure


1. TIRE PRESSURE SENSOR WAKE-UP

Perform the tire pressure sensor wake-up. Refer to "Work Procedure" Work Procedure.
Is the tire pressure sensor wake-up completed?
YES- GO TO 3.
NO- GO TO 2.

2. CHECK TIRE PRESSURE SENSOR ACTIVATION TOOL

Check tire pressure sensor activation tool.
Is the inspection result normal?
YES- GO TO 3.
NO- Replace the battery of tire pressure sensor activation tool or repair/replace the tire pressure sensor activation tool.

3. TIRE PRESSURE SENSOR ID REGISTRATION

Perform tire pressure sensor ID registration. Refer to "Work Procedure" Service and Repair.

CAUTION:
To perform ID registration, observe the following points:
- Never register ID in a place where radio waves are interfered (e.g. radio tower).
- Never register ID in a place close to vehicles including TPMS.
Is tire pressure sensor ID registration completed?
YES- INSPECTION END
NO- GO TO 4.

4. CHECK TIRE PRESSURE SIGNAL

Change the work location and perform ID registration again.
NOTE:
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 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" Removal and Installation.
All wheels do not react.-Check the tire pressure receiver. Refer to "Component Function Check" Testing and Inspection.
