DTC C1505: STEERING ANGLE SENSOR (SIGNAL SEIZURE OR ABNORMAL NEUTRAL POINT)
The steering wheel sensor output value does not fluctuate for more than 20
seconds although the vehicle speed is 15 km/h or more and the G and yaw rate
sensor output value is fluctuating. The neutral point has been +/- 180 deg or more and the vehicle speed remains
10 km/h or more for at least one second.
DTC C1506: STEERING ANGLE SENSOR (ABNORMAL STEERING ANGLE)
The steering wheel sensor sets the DTC.
