U0415 means Invalid Data Received From Anti-Lock Brake System (ABS) Control Module. A module received a message from the anti-lock brake system (abs) control module but the data was out of range or did not make sense. It is a generic OBD-II code, so the definition is the same on any make, but the most likely cause varies by engine; confirm with a scan tool and the service information for your vehicle before buying parts.
What U0415 means
Modern vehicles have many control modules that share information over a network, usually called the CAN bus. Codes starting with U mean a module has stopped hearing another one, and voltage and processor codes mean a module is not getting clean power or has an internal fault. Low battery voltage, poor grounds, blown fuses and damaged wiring cause many of these codes, so test the battery and charging system first.
U0415 symptoms
- Warning lights
- Features working erratically
- Check engine light on some vehicles
Common causes of U0415
- Fault in the sending module or one of its sensors
- Software mismatch after a module replacement
- Low voltage or poor grounds
- Network wiring problems
How to diagnose U0415
- Read codes from the sending module
- Check module software versions
- Check battery voltage and grounds
- Inspect network wiring
Can you drive with U0415?
It depends on the system affected; get it diagnosed.
U0415 tips
Invalid data from the ABS module often traces back to a wheel speed sensor; read the ABS module codes for the root cause.
Will U0415 clear itself?
If the fault stops, the computer turns off the check engine light by itself after several drive cycles without seeing it again, and the code stays in memory as history for a while. Clearing U0415 with a scan tool after a repair is fine, but if the cause is still there the code returns, sometimes within one drive. Disconnecting the battery also clears codes on most vehicles, but it erases learned fuel trims and idle settings as well.

When it is more than a sensor
Voltage and network codes come from wiring, the battery, the charging system or a module, not from engine or transmission wear. If a lost-communication code has left the transmission in limp mode, rule out the module and wiring before deciding the unit has failed, and see our transmissions only if testing confirms internal damage.
