U0415 U0xxx · Network (U) High severity
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.
Severity guidance: High — stop driving and diagnose now; risk of further damage
Symptoms you will notice
- ESP and steering warnings
- ADAS unavailable
- Inconsistent vehicle dynamics behaviour
Common causes
Ordered from most to least likely — start at the top.
- 1 ABS module not calibrated
- 2 Software mismatch
- 3 Corrupted bus data
- 4 Incorrect module fitted
How to diagnose it
Cheapest and least invasive first — most of these codes are not a parts problem.
- ✓ 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.
Repair options
- Perform required calibrations
- Correct coding or update software
- Fit the correct module
U0415 — frequently asked questions
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.
