U0415 on 2020-2022 Ford Escape: Causes and Fixes for Invalid ABS Module Data

What's Unique About the 2020-2022 Ford ESCAPE

While U0415 can be caused by wiring or hardware faults on any car, Ford has specifically identified a software problem in the Power Steering Control Module (PSCM) as a primary cause for this code on 2020-2022 Escapes built on or before March 23, 2022. This is documented in Technical Service Bulletin (TSB) SSM 51437. This means the most common fix isn't replacing a part, but rather having a dealer update the PSCM's software. This same issue affects other vehicles on the same C2 platform, including the 2020-2022 Lincoln Corsair, 2021-2022 Bronco Sport, and 2022 Maverick.

Most Likely Causes

1. Power Steering Control Module (PSCM) Software Glitch 🔴 High Probability Ford identified a specific software issue affecting 2020-2022 Escape, Corsair, 2021-2022 Bronco Sport, and 2022 Maverick vehicles built on or before March 23, 2022, as detailed in TSB SSM 51437.
   How to confirm: A Ford dealer or qualified shop must check the vehicle's build date and the current PSCM software version against the latest available version using the Ford Diagnostic and Repair System (FDRS). The presence of codes U0415, C0051:67, and U0418:86 together is a strong indicator.
   Typical fix: Update the Power Steering Control Module (PSCM) to the latest software level using the FDRS scan tool. This is a software re-flash, not a parts replacement.
   Est. part cost: $0
2. Wiring Harness or Connector Fault 🟡 Medium Probability Wiring for the ABS module and wheel speed sensors is exposed to elements, vibration, and potential road debris. Connectors can become corroded or wires can chafe, leading to intermittent or lost signals. High-pressure washing of the undercarriage can sometimes force water into connectors, causing issues.
   How to confirm: Visually inspect the wiring harness leading to the ABS module and all four wheel speed sensors for damage, corrosion, or loose connections. Pay close attention to areas where the harness may rub against the frame or suspension components. Perform a continuity or 'wiggle' test on suspect wires.
   Typical fix: Repair the damaged section of the wiring harness or clean/replace the corroded connector. Ensure connectors are fully seated and sealed.
   Est. part cost: $10-$50
3. Defective ABS Control Module ⚪ Low Probability
   How to confirm: This is diagnosed by exclusion. If the PSCM software is confirmed to be up to date (or the TSB does not apply) and all wiring, connectors, and sensors test good, the ABS module itself is the likely culprit.
   Typical fix: Replace the ABS control module. This often requires programming the new module to the vehicle's VIN using a tool like FDRS.
   Est. part cost: $400-$900

Rare But Worth Checking

• Failing Wheel Speed Sensor: A faulty wheel speed sensor can send erratic data to the ABS module, which then broadcasts this invalid data, triggering the U0415 code in other modules. This will usually be accompanied by a specific wheel speed sensor fault code (e.g., C0035).
• Low Battery Voltage or Failing Alternator: Low system voltage can cause unpredictable communication errors between various control modules. It's a simple and important check before diving into more complex diagnostics.
• Software Glitch in another Module (e.g., IPMB): While the PSCM is the known culprit on the Escape, other Ford models have shown that a U0415 code can be triggered by software issues in other modules. For example, TSB SSM 49437 for the 2020-2021 Explorer/Aviator notes that a U0415 can be stored in the Image Processing Module B (IPMB) due to a software fault there. This highlights the networked nature of the problem.

Diagnosis Steps

1. Connect a high-level diagnostic scan tool (like the Ford FDRS) capable of reading codes from all vehicle modules (ABS, PSCM, IPMA, PCM).
2. Check the vehicle's build date. If it was built on or before March 23, 2022, TSB SSM 51437 is highly relevant.
3. Check for the presence of U0415 (in PSCM), C0051:67 (in ABS), and U0418:86 (in IPMA) together. Their combined presence strongly indicates the software issue from TSB SSM 51437.
4. If the TSB applies, the primary step is to have a Ford dealer or qualified shop update the PSCM software to the latest version.
5. If the software update does not resolve the issue or the TSB does not apply, test the vehicle's battery and charging system to ensure stable voltage above 12V.
6. Perform a thorough visual inspection of the wiring harness and connectors for the ABS module and all wheel speed sensors. Look for chafing, corrosion, or water intrusion.
7. Using the scan tool's live data function, monitor the output from all four wheel speed sensors 🎬 Watch this guide on how to diagnose ABS light issues. while driving to check for erratic readings or dropouts.
8. If all other steps fail to identify the fault, the ABS control module itself is the most likely cause and may require replacement and programming.

Mechanic-Grade Diagnostic Values

• HS-CAN Bus Resistance — expected: Approximately 60 Ω (with battery disconnected, measured between pins 6 and 14 of the OBD-II port). Failure: A reading of 120 Ω indicates one of the two terminating resistors (in the PCM or Instrument Cluster) is offline. A reading near 0 Ω indicates a short between the CAN High and CAN Low wires.
• HS-CAN High Voltage (Key On, Engine Off) — expected: Fluctuating between 2.5V and 3.5V. Failure: Stuck at a constant voltage, or readings outside the expected range, indicates a bus fault.
• HS-CAN Low Voltage (Key On, Engine Off) — expected: Fluctuating between 2.5V and 1.5V. Failure: Stuck at a constant voltage, or readings outside the expected range, indicates a bus fault.
• ABS Module Power Supply Voltage — expected: 12V (± 0.5V). Failure: Low voltage suggests a problem with the power feed circuit or fuse.

Hidden / Shadow Codes Worth Checking

• U0415:00: Invalid Data Received From ABS Control Module: No Sub Type Information. This is the specific code stored in the PSCM as noted by TSB 51437. (see via Ford FDRS or other high-level scan tool capable of reading manufacturer-specific codes.)
• C0051:67: Steering Wheel Position Sensor: Signal is Incorrect After Event. This code is stored in the ABS module and is part of the known pattern related to the PSCM software glitch. (see via Ford FDRS or other high-level scan tool capable of reading manufacturer-specific codes.)
• U0418:86: Invalid Data Received From Brake System Control Module A: Signal is Invalid. This code is stored in the Image Processing Module A (IPMA) and completes the trio of codes pointing to the TSB fix. (see via Ford FDRS or other high-level scan tool capable of reading manufacturer-specific codes.)

Scan Tool Commands That Help

• Ford Diagnostic and Repair System (FDRS): PSCM - Power Steering Control Module Configuration — This is the specific function used to update or re-flash the PSCM software, which is the primary fix for the issue described in TSB 51437.
• Ford Diagnostic and Repair System (FDRS): Programmable Module Installation (PMI) — Used when replacing a module like the PSCM or ABS module. It retrieves configuration data from the old module (if possible) and programs the new one to ensure it communicates correctly with the vehicle.

Wiring & Ground Locations

• ABS Control Module Fuses — In the under-hood fuse box: Fuse F15 (40A) for the ABS control pump and Fuse F16 (25A) for the ABS control valves.. A loss of power to either the ABS pump or valves can cause the module to malfunction and send invalid data, triggering a U0415 code in other modules.
• ABS Module Assembly — Typically located in the engine compartment, attached to the firewall, identifiable by the multiple steel brake lines connected to it.. This is the physical location to inspect for loose connectors or damaged wiring that could be causing the communication fault.
• PSCM (Power Steering Control Module) — On 2020+ Escapes, the power steering motor and control module are integrated into the steering column inside the cabin, not on the steering rack itself.. Since the PSCM is the module that sets U0415 due to the software glitch, knowing its location is critical for advanced diagnosis if the software update fails and wiring needs to be checked at the module.

Real Owner Repair Stories

• Ford Edge Forum (2015 Ford Edge Sport AWD) — ABS, traction control, stability control, and park aid lights were on. Code U0415 was present after a previous repair replaced a wheel speed sensor.
  ❌ Tried (didn't work) Replacing the right rear ABS sensor (this fixed a different code but U0415 appeared afterward).
  ✅ What actually fixed it The owner performed a thorough inspection of the entire wiring harness from the ABS sensors to the ABS pump and found a fault. After repairing the wiring harness, all warning lights went out and all systems returned to normal. A continuity check confirmed the fix.

Model Year Variations Within This Range

• 2020-2022: The power steering system design integrates the PSCM and motor into the steering column, unlike earlier designs where it was on the steering rack. This is relevant as the PSCM is the module storing the U0415 code per the TSB.
• Vehicles built on or before March 23, 2022: These vehicles are specifically called out in TSB 51437 as potentially having the PSCM software glitch. Vehicles built after this date should have the updated software from the factory, making the TSB less likely to be the cause.
