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.CHECK TIRE PRESSURE SENSOR ACTIVATION TOOL
Check tire pressure sensor activation tool.
Is the inspection result normal? YES >> GO TO 2.
NO >> Replace the battery of tire pressure sensor activation tool or repair/replace the tire pressure sensor activation tool.
2.TIRE PRESSURE SENSOR ID REGISTRATION
Perform tire pressure sensor ID registration. Refer to WT-21, "Work Procedure"
CAUTION: To perform ID registration, observe the following points:
Is tire pressure sensor ID registration completed? YES >> Inspection End.
NO >> GO TO 3.
3.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 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.
*: 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 WT-61, "Removal and Installation".
All wheels do not react.>>Replace BCM. Refer to BCS-75, "Removal and Installation" (with Intelligent Key System) or BCS-135, "Removal and Installation" (without Intelligent Key System).
