U0415 U0xxx · 网络通信（U） 高严重度
Invalid Data Received from ABS Control Module
Another module received implausible data from the ABS module. Stability, steering and ADAS functions may all be limited as a result.
严重程度说明： 高——立即停车诊断，继续行驶有扩大损坏的风险
你会注意到的故障现象
- ESP and steering warnings
- ADAS unavailable
- Inconsistent vehicle dynamics behaviour
常见原因
按可能性从高到低排列——从最上面开始查。
- 1 ABS module not calibrated
- 2 Software mismatch
- 3 Corrupted bus data
- 4 Incorrect module fitted
如何排查
先做花钱最少、侵入最小的检查——大多数这类码不是零件问题。
- ✓ Check whether the ABS module or its coding was recently changed.
- ✓ Verify calibration status (steering angle, yaw, longitudinal).
- ✓ Compare software versions.
- ✓ Confirm bus signal quality with a scope.
维修方案
- Perform required calibrations
- Correct coding or update software
- Fit the correct module
U0415 —— 常见问题
Why is ADAS affected? +
Camera and radar functions rely on ABS-supplied vehicle dynamics data.
Can calibration alone fix it? +
Often yes, especially after suspension, steering or module work.
