Inspection Procedure

1. Perform the zero point calibration of the yaw rate and deceleration sensor (see CALIBRATION  ).

   HINT:

   • When the stored zero point of the yaw rate and deceleration sensor is erased, the steering sensor zero point is also erased.
   • If the zero point and output value of the yaw rate and deceleration sensor and the output values of the speed sensors are not normal, the steering sensor zero point cannot be learned normally even if the vehicle is driven straight ahead at 35 km/h (22 mph) or more.

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. 

NG: ADJUST FRONT WHEEL ALIGNMENT 

OK: Go to next step. 

1. Turn the ignition switch OFF.
2. Clear the DTC (see DTC CHECK / CLEAR  ).
3. Check if the same DTC is recorded (see DTC CHECK / CLEAR  ).
