- Applies to
- All OBD-II vehicles (any make or model)
- Est. repair cost
- $50 – $800
- Time to fix
- 1–4 hours
What it means
Causes include an ABS module or wheel-speed-sensor fault, CAN noise, or a software mismatch. U0415 is a generic OBD-II network/communication ("U") code defined in the SAE J2012 standard, so it applies to virtually any modern OBD-II vehicle regardless of make. These faults usually point to the vehicle's data bus (often CAN) or a module that has dropped off the network. Fix the wiring/module fault, then clear the code with a scan tool.
Symptoms
- ABS/traction/stability lights on
- Speed-related data errors
- Those systems may be disabled
How to fix it
- 1
Scan the ABS module
1. Check the ABS module for its own codes (e.g. wheel-speed sensors) and fix those first.
- 2
Check wiring/software
1. Inspect the CAN wiring and confirm compatible software. 2. Repair, then clear the code.

What usually causes U0415?
Often a wheel-speed-sensor or ABS-module fault makes the ABS broadcast bad data. Diagnose the ABS module's own codes first.
