Inspection Procedure
NOTE:
When replacing the brake actuator assembly, perform zero point calibration (See CALIBRATION
).
- PERFORM ZERO POINT CALIBRATION OF YAW RATE AND ACCELERATION SENSOR
- 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 cleared, steering angle sensor zero point will also be cleared.
- 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, a correct steering angle sensor zero point cannot be acquired even if the vehicle is driven straight ahead at 35 km/h (22 mph) or more.
- Perform zero point calibration of the yaw rate and acceleration sensor (See CALIBRATION
).
- CHECK STEERING ANGLE SENSOR ZERO POINT CALIBRATION
- Drive the vehicle straight ahead at 35 km/h (22 mph) or more for at least 5 seconds.
- Check that the center position of the steering wheel is correctly set while driving straight ahead.
HINT:
If front wheel alignment and steering position are adjusted as a result of an off-centered position of the steering wheel, acquire yaw rate and acceleration 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 OR STEERING POSITION (See FRONT WHEEL ALIGNMENT )
OK: Go to next step
- RECONFIRM DTC
- Turn the ignition switch off.
- Clear the DTCs (See DTC CHECK / CLEAR ).
- Start the engine.
- Drive the vehicle and turn the steering wheel to the right and left at a speed of 35 km/h (22 mph) or more.
- Check if the same DTC is recorded (See DTC CHECK / CLEAR
).
