U0415
Invalid Data Received From Anti-Lock Brake System (ABS) Control Module
Communication network (ABS / brakes)
Generic OBD-II
Medium
What it means
U0415 sets when a control module reads data from the ABS control module that is missing, out of range, or implausible. The usual effect is that ABS, traction, and stability control shut off as a precaution — your normal brakes still work, but the anti-lock and stability features are disabled until it's fixed.
Medium
Can I keep driving? Your normal (base) brakes still work, but ABS, traction, and stability control may be disabled — brake with extra care, especially on slippery roads.
Common symptoms
What you'll notice
- ABS, traction, and stability warning lights on, usually with the check-engine light
- ABS and stability/traction control disabled
- Speedometer or wheel-speed readings may misbehave on some vehicles
- Normal (non-ABS) braking still available
- Related communication codes stored in other modules
Common causes
Most likely first
- Faulty ABS control module or its power/ground supplyLikely
- Corroded, loose, or damaged connectors and data-bus (CAN) wiringCommon
- Low or unstable battery and charging-system voltageCommon
- Software incompatibility after a module was replaced or updatedLess often
- An underlying wheel-speed sensor or ABS fault reported by the moduleLess often
How to diagnose & fix
Work through it in order
- Scan all modules and record stored codes and freeze-frame data before clearing.
- Check battery and charging voltage — low or noisy voltage is a common cause of bus faults.
- Inspect connectors and wiring to the ABS control module and along the data bus.
- If a module was recently replaced or flashed, confirm the software is compatible.
- Run the manufacturer's pinpoint tests on the ABS module and its wheel-speed inputs; replace only if confirmed.
FAQ
Quick answers
Is it safe to drive with U0415?+
Your base brakes still work, so you can drive carefully, but ABS and stability control may be off — allow extra stopping distance and get it fixed soon, especially before wet or icy conditions.
Can I just clear U0415?+
You can, but if the ABS module or its data link is still faulty the code returns and the ABS/stability warning lights come back on.
