Toyota RAV4 (XA40) 2013-2018 Service Manual: Steering angle sensor zero point malfunction

Toyota RAV4. 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 seconds. The ecu also stores the previous zero point.

If front wheel alignment or the steering wheel position is adjusted without disconnecting the negative battery terminal, or if the yaw rate and deceleration sensor zero point is not set after the adjustments have been completed, the skid control ecu detects the difference between the previously stored zero point and the newly learned zero point and outputs this dtc to indicate a poor adjustment.

Indication of the steering sensor zero point malfunction is canceled by turning the ignition switch off.

Inspection procedure

Notice:

When replacing the abs and traction actuator, perform zero point calibration (see page bc-24).

  1. Perform yaw rate and deceleration sensor zero point calibration

  1. Perform the zero point calibration of the yaw rate and deceleration sensor (see page bc-24).

Hint:


  1. Check steering sensor

  1. Drive the vehicle straight ahead at 35 km/h (22 mph) or more for 5 seconds or more.
  2. Check that the centered position of the steering wheel is correctly set while driving straight ahead.

Hint:

If the front wheel alignment and steering position are adjusted due to an incorrectly centered position of the steering wheel, set the yaw rate and deceleration sensor zero point again after the adjustments are completed.

Ok: the center position of the steering wheel is correctly set.



  1. Reconfirm dtc

  1. Turn the ignition switch off.
  2. Clear the dtc (see page bc-47).
  3. Check if the same dtc is recorded (see page bc-47).
