2016-2023 F-150 & Raptor ABS Module Failure: Recalls, Diagnosis, and Programming
A complete guide to diagnosing and replacing the integrated ABS control module assembly in your Ford F-150, including critical information on recalls and mandatory programming.
- A leaking master cylinder is a primary cause of failure on 2014-2017 models due to a major safety recall (Ford 20S31).
- All replacement modules, new or used, MUST be electronically programmed to the truck's VIN and specific options to function.
- DIY programming is possible for advanced users with FORScan software, which can save hundreds in dealer fees.
- This part is a complete assembly including the master cylinder, ABS pump, and control module; it is not just a small electronic box.
Symptoms of a Failing ABS Control Module
When the ABS module begins to fail, your truck will give you several clear warning signs. Ignoring them is not recommended, as it compromises key safety features.
- ABS and Traction Control Warning Lights: The most common symptom is the illumination of the ABS and traction control (or AdvanceTrac) warning lights on your dashboard.
- "Service AdvanceTrac" Message: This message will often appear in the instrument cluster display along with the warning lights.
- Brake Warning Light: A red brake warning light may also illuminate, sometimes indicating a serious issue like low brake fluid or a hydraulic problem within the ABS unit.
- ABS Pump Motor Running Constantly: You might hear a buzzing or humming sound from the engine bay, even when the truck is off. This is the ABS pump motor continuing to run, which can drain the battery. 🎬 See this fix for an ABS pump motor that won't stop running.
- Unusual Brake Pedal Feel: The brake pedal may feel spongy, hard, require more effort than usual, or sink towards the floor. This can indicate a serious internal failure.
- Audible Chimes and Alerts: The truck's warning system will likely produce audible chimes to get your attention when these faults are detected.
Common Diagnostic Trouble Codes (DTCs)
A proper diagnosis requires a scan tool capable of reading Chassis (C-prefix) and Network (U-prefix) codes. Common codes associated with ABS module failure include:
- C0034: Right Front Wheel Speed Sensor Circuit
- C1013:09: ABS Module Software Issue
- C1073: Pump Motor Control Circuit
- C1165 / C1175: Rear Wheel Speed Sensor Input Circuit Failure
- C1298 / C1299: Rear Wheel Speed Sensor Input Signal Fault
- C1963: Stability Control Inhibit Warning
- U-prefix codes (e.g., U0415): These indicate a loss of communication with the ABS module.
Pro Tip: Before condemning the entire ABS module, always check the basics first. Inspect the wheel speed sensors at each wheel for damage or debris, check the brake fluid level, and verify the ABS-related fuses in the under-hood power distribution box. 🎬 Watch: How to find and replace the ABS module fuse. A much cheaper sensor or fuse could be the root cause of your warning lights.
Known Issues, Recalls, and Technical Service Bulletins (TSBs)
Ford Recall 20S31 (NHTSA Campaign 20V332000)
This is the most significant issue affecting these trucks. On certain 2014-2017 F-150 models (primarily those with the 3.5L EcoBoost engine), the brake master cylinder can develop an internal leak. Brake fluid seeps from the master cylinder directly into the attached electronic brake booster, contaminating and destroying the electronics of the ABS control module assembly. This can lead to a loss of front braking power, increased pedal effort, and longer stopping distances. The remedy involves replacing the master cylinder and, if a leak is found, the entire brake booster/ABS module assembly.
TSB 20-2035
For some 2018-2019 F-150 models with specific configurations (3.5L EcoBoost, 145-inch wheelbase, XL/STX trim, max trailer tow package), this TSB addresses an issue where the stability/traction control light may illuminate with DTCs C0051:54 or C0051:64. The fix is not a part replacement but a reprogramming of the ABS module with updated software.
Programming & Calibration: This is Not Plug-and-Play
Warning: A replacement ABS module assembly, whether new or used, MUST be programmed to your vehicle's specific VIN and configuration. Simply installing the part will not work, and the truck may not be safe to drive.
The ABS module needs to know your truck's specific features, like engine size, drivetrain, and whether it has options like Adaptive Cruise Control. This information is stored in what is known as "As-Built" data. The correct As-Built data must be loaded onto the replacement module.
Programming Options:
- Ford Dealership: The most straightforward but often most expensive option. 🎬 Watch: A step-by-step guide to the ABS module programming procedure. They use the Ford IDS (Integrated Diagnostic System) software to perform the programming.
- Independent Repair Shop: Many professional shops have high-end scan tools (from brands like Autel or Snap-on) that are capable of performing the necessary "Programmable Module Installation" (PMI) and "IVD Initialization" procedures.
- DIY with FORScan: For the advanced DIY mechanic, FORScan software provides a powerful and affordable option. Using a laptop and a compatible OBD-II adapter, you can download your truck's original As-Built data from Ford's servers and write it to the new module. This is a very popular method among truck enthusiasts.
Buying a Used ABS Control Module Assembly
Given the high cost of a new unit, a used OEM assembly is a very popular and cost-effective repair. Here’s what to look for:
- Verify Part Numbers: Match the OEM part number from your original unit to the used part. While there are many interchangeable numbers, a direct match is the safest bet.
- Check for Leaks: The most important inspection is to check for any signs of brake fluid leakage between the master cylinder (the aluminum part with the fluid reservoir) and the booster/module body (the black part). A unit showing any signs of a leak is likely compromised due to the recall issue.
- Inspect Connectors: Ensure the large electrical connector and its pins are clean, straight, and free of corrosion. Damaged pins can cause communication errors.
- Confirm Options: The most critical compatibility check is for Adaptive Cruise Control. Modules are different for trucks with and without this feature. Verify the donor vehicle's options if possible.
- Why Used OEM is a Good Choice: For a complex, safety-critical electronic and hydraulic assembly like this, a recycled original Ford part is often more reliable than a new, unproven aftermarket unit. You get the original factory quality and fitment at a fraction of the price.

Frequently Asked Questions (FAQ)
Do I have to program a replacement ABS module?
Yes, absolutely. The module must be configured with your truck's specific "As-Built" data to function correctly with the other systems in the vehicle. Failure to program the module will result in continued warning lights and a non-functional ABS/traction control system.
Can I just replace the electronic part of the module?
On some older vehicles, the electronic module could be unbolted from the hydraulic pump. However, on these modern F-150s, the unit is sold and replaced as a complete assembly including the master cylinder. Attempting to separate them is not recommended and may not be possible.
What is FORScan and can it really program the ABS module?
FORScan is a powerful software application that allows deep diagnostic and programming access to Ford, Lincoln, and Mazda vehicles. Yes, it is fully capable of performing the Programmable Module Installation (PMI) function required to configure a new or used ABS module to your truck. It requires a compatible OBD-II adapter and a laptop, but it can save you hundreds of dollars in dealer programming fees.
Will my brakes still work if the ABS module fails?
In most failure scenarios, your standard hydraulic brakes will still function. However, you will not have the anti-lock braking, traction control, or stability control safety features. If the failure is due to a major internal hydraulic leak as described in the recall, you could experience a significant loss of braking power, making the vehicle unsafe to drive.
