Toyota RAV4 Service Manual: Different diameter tire malfunction

Toyota RAV4. Different diameter tire malfunction

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.

Toyota RAV4. Different diameter tire malfunction


Inspection procedure

  1. Check tire size

  1. Check the diameter of all 4 tires.

Ok: diameter of all 4 tires are equal.



  1. Check speed sensor rotor

  1. Remove the drive shaft, and check around the speed sensor rotor.

Ok: no scratches or foreign matter on the sensor tip.



  1. Check speed sensor



  1. Check the speed sensor circuit (see page bc-64 or bc- 70).
  1. Check wire harness (skid control ecu - each speed sensor)

  1. Check the speed sensor circuit (see page bc-69 or bc- 70).



  1. Reconfirm dtc

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