Toyota RAV4 Service Manual: Different diameter tire malfunction

Toyota RAV4. 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.

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.

Result




Replace abs and traction actuator assembly

Steering angle sensor zero point malfunction
Description The skid control ecu learns the steering sensor zero point every time the ignition switch is turned on and the vehicle is driven at 35 km/h (22 mph) or more for approximately 5 sec ...

Downhill assist control operation switch (test mode dtc)
Description The downhill assist control switch is connected to the skid control ecu in the abs and traction actuator. Dtc c1379/74 can be detected when the downhill assist control switch se ...

Data list / active test
Read data list Hint: Using the intelligent tester's data list allows switch, actuator and other item values to be read without removing any parts. Reading the data list early in troubleshooting is one way to save time. Connect the intelligent tester (with can vim) to the dlc3. Turn ...
