U0415: Invalid Data Received From Anti-Lock Brake System (ABS) Control Module
A module is receiving data from the ABS control module, but the data is not valid.
Normal risk
Have it checked soon. Stability control may be off.
Short answer · Can I keep driving with U0415?
Normal braking usually remains. Drive carefully and have it checked.
What does U0415 mean?
U0415 is stored when data from the ABS module, such as wheel speed, is missing or implausible. A wheel speed sensor fault in the ABS module is a frequent reason.
What the car does when the code is set
The receiving module ignores the invalid data. Functions that rely on it may be limited and warning lights can come on.
How the system works
Modules check incoming data for plausibility, for example value range and message counters. When the data is present but not plausible, they store an invalid data code naming the sending module.

Possible causes
Listed without ranking. The cause on your car depends on make, engine and mileage — see the maker notes below.
- Fault in the module that sends the dataFor example a sensor fault inside or connected to that module.
- Network interferenceWiring problems can corrupt messages.
- Software mismatchModules with incompatible software versions.
- Low battery voltageUnstable voltage can corrupt data.
How it is diagnosed
- Read codes in the sending moduleCodes stored there often explain why its data is invalid.
- Check battery voltageMake sure supply voltage is stable.
- Check for software updatesA dealer can check for technical service bulletins and updates.
- Test the networkA workshop inspects the wiring if the data keeps arriving corrupted.
Questions about U0415
Why check wheel speed sensors?
Invalid wheel speed data is a common reason for U0415.
Why does one module report another module’s data?
Modules share data; the receiving module notices when values are missing or implausible.
