| Enable Conditions |
- The STN is low more than ±20 degrees for 70msec.
- When the steering wheel is turned more than 370±5 degrees, if center is not detected, ECU detects the failure.
- When the steering wheel angle is higher than 700 degrees ECU detects the failure.
- During straight driving, if the steering wheel angle is larger than 55±5 degree ECU detects the failure.
- When the curve is detected after driving straight, if there is no variation of the steering wheel angle for 3sec, ECU detect the failure.
- While the vehicle drive 60±5 degree ↔ -60±5 degree, if STN is not detected low, ECU detect the failure.
- While steering angle sensor wheel through center, if steering angle sensor is against specification three times, ECU detect the failure.
