U0415 — Invalid Data Received From Anti-Lock Brake System Control Module

vehicle network

Is it safe to drive?

Drive with caution The base brakes usually still work, so careful driving is possible — but ABS and stability control are disabled, which lengthens stopping distances on slippery roads. Fix promptly and avoid harsh driving.

How to diagnose with an OBD scanner

  1. Read the code and freeze frame Connect an OBD2 scanner, confirm U0415 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
  2. Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many U0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
  3. Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the ABS / stability control for damage, corrosion, chafing or poor contact.
  4. Subsystem check Read all four wheel speed PIDs while driving slowly — the faulty sensor drops out or reads implausibly.
  5. Subsystem check Inspect the sensor and tone ring for metal debris and damage near the hub.
  6. Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm U0415 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for U0415 (parts and labor, USD, independent shop rates): Repair sensor wiring: $80–$250; ABS module repair or replacement: $400–$1,200; Replace a wheel speed sensor: $120–$350. Overall, fixing U0415 usually costs between $80 and $1,200. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

Common questions

Will U0415 clear itself?

Sometimes U0415 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.

What are the symptoms of U0415?

Drivers most often notice: ABS or ESC warning light on, ABS not operating during hard braking, speedometer or cruise control issues, brake pedal pulsation changes.

What is the most common cause of U0415?

The most common causes are: blown fuse or low voltage to the ABS module, damaged sensor wiring or corroded connector, failed wheel speed sensor.

The base brakes usually still work, so careful driving is possible — but ABS and stability control are disabled, which lengthens stopping distances on slippery roads. Fix promptly and avoid harsh driving.

How much does it cost to fix U0415?

Repair sensor wiring — $80–$250; ABS module repair or replacement — $400–$1,200; Replace a wheel speed sensor — $120–$350. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

What does U0415 mean?

Seeing U0415 on your scanner? The control unit has caught the ABS / stability control operating outside its calibrated window. The formal description is “Invalid Data Received From Anti-Lock Brake System Control Module”, and the code is grouped under vehicle network faults.

This code does not appear from a single bad reading: the module must see the fault condition repeat under defined operating conditions before it turns on the warning light. The freeze frame captured with U0415 — engine load, rpm, temperature, speed — tells you exactly when the problem occurs, so reproduce those conditions when testing.

What causes U0415?

  • damaged sensor wiring or corroded connector
  • damaged tone (reluctor) ring on the hub
  • blown fuse or low voltage to the ABS module
  • failed wheel speed sensor
  • faulty ABS module or pump motor

Common symptoms of U0415

  • ABS or ESC warning light on
  • ABS not operating during hard braking
  • speedometer or cruise control issues
  • brake pedal pulsation changes
  • stability control disabled message
