Inspection Procedure

1. Clear the calibration data (See CALIBRATION  ).
2. Perform zero point calibration of the yaw rate and acceleration sensor (See CALIBRATION  ).

   HINT:

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

1. Connect the intelligent tester to the DLC3.
2. Drive the vehicle straight ahead at 22 mph (35 km/h) or more for at least 5 seconds.
3. Select the Data List mode on the intelligent tester (See DATA LIST / ACTIVE TEST  ).

   NORMAL CONDITION CHART
   
   

   Tester Display	Measurement Item/Range	Normal Condition
   STEERING ANG	Steering angle sensor / min.: -1,152 deg, max.: 1,150.875 deg	Left turn: Increase Right turn: Decrease

4. Check that the centered position of the steering is correctly set while driving straight ahead.

   OK: 

   When driving straight ahead, the degree is approximately 0. 

   When turning right, the degree shows "- (negative)" values. 

   When turning left, the degree shows "+ (positive)" values. 

NG: ADJUST FRONT WHEEL ALIGNMENT OR STEERING POSITION 

OK: Go to next step 

1. Turn the ignition switch off.
2. Clear the DTC (See DTC CHECK / CLEAR  ).
3. Drive the vehicle and turn the steering wheel to the right and left at the speed of 22 mph (35 km/h).
4. Check if the same DTC is recorded (See DTC CHECK / CLEAR  ).
