Toyota RAV4 (XA40) 2013-2018 Service Manual: Different diameter tire malfunction
Description
The skid control ecu measures the speed of each wheel by receiving signals from the speed sensor.
These signals are used for recognizing that all 4 wheels are operating properly. Therefore, all wheel signals must be equal.
Inspection procedure
- Check tire size
- Check the diameter of all 4 tires.
Ok: diameter of all 4 tires are equal.
- Check speed sensor rotor
- Remove the drive shaft, and check around the speed sensor rotor.
Ok: no scratches or foreign matter on the sensor tip.
- Check speed sensor
- Check the speed sensor circuit (see page bc-64 or bc- 70).

- Reconfirm dtc
- Clear the dtcs (see page bc-47).
- Drive the vehicle at more than 20 km/h (12 mph) for more than 60 seconds.
- Check if the same dtcs are detected.
