DTC C1260: Steering Angle Sensor Circuit-Signal: DTC Detecting Condition

DTC DETECTING CONDITION CHART

Item Detecting Condition Possible cause
DTC Strategy
  • Signal Monitoring
  • Faulty steering angle sensor
  • Incorrect installation of the sensor
Enable Conditions
  • The STN is low more than ±10 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 800 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 3 sec, 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 the steering wheel is turning through center point, if steering angle sensor is against specification more than three times, ECU detect the failure.
Fail Safe
  • Inhibit the ESC control and allow the ABS/EBD control.
  • The ESC warning lamp is activated.
