U0415Invalid Data Received From Anti-Lock Brake System Control Module

U0415 means the module that coordinates your vehicle's network received data from the anti-lock brake system (ABS) control module that it judged invalid or implausible. The ABS module is alive and communicating, but the content of its messages is missing expected values, out of range, or inconsistent with other data on the bus.

Code typeGeneric (all makes)

SeverityMedium

Fix difficultyProfessional

AreaInvalid data received from a module

Symptoms you may notice

Anti-lock brake system (ABS) warning light illuminated on the dashboard
Traction control or stability control warning light on, often together with the ABS light
Often no symptoms besides the warning light, with normal braking feel
Disabled ABS, traction control, or stability control functions during the fault
Intermittent warning lights that come and go with temperature or vibration
A stored U0415 with no other drivability complaints

Common causes, most likely first

Corroded, loose, or damaged ABS module connector or pins
Chafed, shorted, or open controller area network (CAN) bus wiring between the ABS module and the network gateway
Failing ABS control module internal circuitry or software
Low or unstable battery voltage causing the ABS module to transmit corrupted data
Poor ground connection at the ABS module or chassis ground point
Another module on the bus flooding the network and corrupting ABS messages
Aftermarket electrical accessories or improper repairs disturbing the CAN bus

How to diagnose and fix it

Scan all modules for stored codes and record freeze-frame data before clearing anything
Inspect the ABS module connector and pins for corrosion, looseness, or pushed-out terminals
Test battery voltage and charging system output, then load-test the battery
Check CAN bus wiring between the ABS module and the gateway for opens, shorts, and chafing
Verify ABS module ground circuit resistance and clean or tighten ground points
Perform a wiggle test on the ABS harness while watching live data for dropouts
If wiring and power are good, reprogram or replace the ABS control module and recheck

Why U0415 is often a wiring fault

U0415 is a communication content fault, not a hard ABS failure, so the ABS module can still pass a basic ping test while sending invalid data.
A weak battery or failing alternator is a common hidden cause because low voltage corrupts the messages the ABS module transmits.
Technicians who replace the ABS module first often find the real problem is a corroded connector or chafed CAN wire.
Another module shorting the bus can corrupt ABS messages and set U0415 even though the ABS module itself is healthy.
Clearing the code without checking freeze-frame data can erase the conditions that would identify the true cause.

Can I keep driving with U0415?

The vehicle usually remains drivable with normal base braking, but ABS, traction control, and stability control may be disabled. Avoid hard braking, slippery surfaces, and towing until the fault is diagnosed, and repair it promptly because safety systems are affected.
