U0415: Invalid data received from the ABS control module
Another module is receiving impossible or inconsistent data from the ABS, almost always a wheel speed. A wheel sensor or its tone ring is typical.
| Code | U0415 |
|---|---|
| System | Communication network |
| Group | U04xx, Invalid data between control units |
| Type | Generic: it means the same on every make |
| Can you keep driving? | With care |
What U0415 means
The ABS control unit shares each wheel speed and the vehicle speed over the network, used by the engine, gearbox, dashboard and steering. This code is stored by another module when that data arrives out of range or with errors. The ABS unit normally has its own codes pointing to the wheel in trouble.
Most common causes
- Dirty or damaged wheel speed sensor, or a broken sensor wire
- Damaged tone ring or magnetic wheel bearing
- Mismatched tyre sizes or very uneven tyre wear
- Low or unstable battery voltage
- Loose or corroded ABS unit connector
- Faulty ABS unit or one with the wrong software
Symptoms
- ABS and stability control warning lights on
- Speedometer failing or jumping
- Odd gear changes on automatic cars
- Cruise control cutting out
Can you drive with U0415?
With care The brakes still work, but ABS and stability control may be off. Drive gently and leave extra distance until it is fixed.

How to check it
With the reader, watch all four wheel speeds live while driving slowly in a straight line: the one reading zero or jumping is the suspect. Also check that all four tyres are the same size.
How to read and clear U0415 with Final OBD
Plug an OBD2 scanner in under the steering wheel, switch the ignition on and open Final OBD. Under Faults you’ll see U0415 with its description and whether it’s confirmed, pending or permanent.
If the engine stores it over standard OBD, with FREE you read this code with its explanation for nothing and clear it. With PRO you also read the faults of every control unit and clear them in all of them.
Clearing the code only turns the light off: if the cause is still there, it comes back. Clear it once it’s fixed, and not right before an inspection. It’s all in how to read and clear fault codes and in inspections and OBD.

How do you clear U0415?
With an OBD2 scanner and an app like Final OBD, which clears it for free if it’s stored by the engine control unit. But clearing it only turns the light off: if the cause isn’t fixed, U0415 comes back.
Read it on your car
Final OBD reads and clears engine faults through standard OBD for free, each one explained in plain English. With PRO it also reads the faults of every control unit, each make’s own codes included, and clears them in all of them.
