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.

Figures reflect only diagnostic scans recorded through our own apps and tools.

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.
