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.

Result




Replace abs and traction actuator assembly
