C0200 C0xxx · シャシ (C) 重大度高
Steering Angle Sensor / Transfer Case Range Fault
The steering angle signal is missing, out of range or not learned. Stability control and electric power steering assistance depend on it.
重大度の目安： 高 — 走行を止めてすぐに診断してください。さらに損傷が広がる恐れがあります
確認できる症状
- ESP lamp on
- Steering assist inconsistent
- Lane-keeping and ADAS functions disabled
- Vehicle pulls assistance strategy into default
主な原因
可能性の高い順に並んでいます。上から順に確認してください。
- 1 Steering angle sensor not calibrated
- 2 Clock spring failure
- 3 CAN data fault from the sensor
- 4 Steering work without recalibration
点検・修理の手順
費用が安く侵襲の小さい項目から — これらのコードの大半は部品の問題ではありません。
- ✓ Check whether the steering or suspension was recently worked on — recalibration is then the likely fix.
- ✓ Read live steering angle and turn lock-to-lock to check the sweep.
- ✓ Perform the manufacturer's zero-point calibration.
- ✓ Inspect the clock spring if the signal drops intermittently.
修理の選択肢
- Perform steering angle sensor calibration
- Replace the clock spring
- Repair the CAN wiring
C0200 — よくあるご質問
Why does it appear after a wheel alignment? +
The sensor's zero point no longer matches straight-ahead. Recalibrate after any steering or alignment work.
Does ADAS stop working too? +
Yes — lane-keeping and camera-based functions rely on a valid steering angle signal.
