DTC Information: DTC Detecting Condition

Item Detecting Condition Possible Cause
DTC Strategy
  • Pressure sensor offset Monitoring
  1. Incorrect installation
  2. Incorrect calibration of steering angle sensor
  3. Faulty steering angle sensor
Enable Conditions
  • If following interference and signal disturbance is detected.
  1. During straight driving, If the steering wheel angle is larger than 55 degree ECU detects the failure.
  2. When the steering wheel angle is out of sensor spec, ECU detects the failure.
  3. When the difference between estimated angle and measured angle of the SAS sensor is larger than 50deg/s, failure is detected, if the fault condition is maintained for t>=1.5sec.
  4. In case that diagnostic signal fault of SAS was happened for more than 100ms within normal voltage condition.
  5. When the steering wheel angle is under 3deg during left/right curve, ECU detects the failure.
MIL
  • The ESP (ESC)/DBC warning lamp is activated. The AVH warning lamp is activated in case of the vehicle equipped with AVH.
Reset condition
  • 1), 3), 5).: SAS signal is normal on a driving above 20 km/h (12.4 mi/h) after ignition switch turned On again and SAS signal on right/left turn is larger than 25deg. 2), 4).: Turn ignition switch off and on.
