U0415 Invalid data received from ABS control module
What U0415 means
The ABS module broadcasts wheel speed and braking data to other modules such as the engine, gearbox and instrument cluster. U0415 means one of those modules is receiving messages from the ABS module that are present but implausible. The real fault is often inside the ABS system itself, such as a failed wheel speed sensor.
U0415 is a generic SAE J2012 code: it means the same on every make. The exact cause still depends on the car, so read the freeze-frame data before replacing parts.

Parts and labour at an independent workshop in Europe. Main dealers charge more; the cause decides the bill, not the code.
Symptoms
- ABS, traction or stability control warning lights
- Speedometer reading wrongly or dropping out
- Cruise control or start-stop not working
- Automatic gearbox shifting oddly
Common causes
- Faulty wheel speed sensor or damaged tone ring
- Fault code already stored in the ABS module
- Low battery voltage or poor ABS module ground
- Damaged CAN bus wiring or corroded ABS connector
- ABS module software or internal fault
Can I keep driving with U0415?
Normal braking still works, but ABS and stability control may be disabled. Drive with extra care, especially on wet or icy roads, and have it checked within one or two weeks.
What to check first
- Read codes in the ABS module and repair any wheel speed sensor or ABS faults first
- Compare all four wheel speeds in live data while driving
- Check battery voltage and the ABS module power, ground and connector
- Check for ABS module software updates before considering replacement
