U0415 on 2022 Ford Maverick: Causes, Symptoms, and Fixes

What's Unique About the 2022-2022 Ford MAVERICK

The 2022 Maverick is built on Ford's C2 platform, which it shares with the Bronco Sport, Escape, and Lincoln Corsair. These vehicles have highly integrated electronic systems where features like Pre-Collision Assist, Adaptive Cruise Control, and electric power steering all depend on receiving accurate data from the ABS module. A communication fault like U0415 can cause a cascade of warning lights and disable these important driver-assist features. Ford has specifically identified this scenario in Technical Service Bulletins (SSM 51437, SSM 50771), pointing to a software issue in the PSCM as the primary cause for vehicles built on or before March 23, 2022, rather than a hardware failure.

Most Likely Causes

1. Module Software/Firmware Needs Update 🔴 High Probability As a newer model with complex integrated electronics, software glitches are common. Ford has issued TSBs (SSM 51437 and SSM 50771) that directly point to a software issue in the Power Steering Control Module (PSCM) as the cause for vehicles built on or before March 23, 2022.
   How to confirm: A Ford dealer or a qualified shop with a Ford Diagnosis and Repair System (FDRS) scan tool can check for available software updates for the PSCM and ABS modules. The presence of codes C0051:67 and U0418:86 alongside U0415 is a strong indicator of this specific software issue.
   Typical fix: Updating the Power Steering Control Module (PSCM) software to the latest version using FDRS.
   Est. part cost: $0 (if under warranty)
2. Low Battery Voltage or Poor Ground 🟡 Medium Probability → Shop Vehicle Battery Modern vehicles are highly sensitive to battery voltage. Mavericks, in particular, have been noted by owners and dealership employees to suffer from low battery states of charge, even when new. A weak or dying 12V battery can cause numerous, seemingly unrelated electronic glitches and communication errors between modules.
   How to confirm: Test the 12V battery with a digital multimeter or a load tester to check its health (should be >12.4V at rest). Inspect the main battery terminals and chassis ground points for corrosion or looseness. Some owners on MaverickTruckClub have had their 12V batteries replaced under warranty to solve electronic issues.
   Typical fix: Charge or replace the 12V battery. Clean and tighten all ground connections.
   Est. part cost: $0-$300
3. Failing ABS Control Module ⚪ Low Probability → Shop ABS Control Module
   How to confirm: If software updates do not resolve the issue and all wiring and power/ground connections are confirmed to be good, the ABS module itself may be faulty. This requires advanced diagnostics with a professional scan tool to monitor live data output from the module.
   Typical fix: Replace the ABS control module and program the new module to the vehicle using a tool like FDRS. This is not a plug-and-play part.
   Est. part cost: $500-$1000
4. Wiring Harness or Connector Issue ⚪ Low Probability
   How to confirm: Visually inspect the wiring harnesses and connectors going to the ABS module and wheel speed sensors. Check for any signs of damage, corrosion, or loose pins. A user on MaverickTruckClub found a wiring open on the wheel speed sensor harness (Part No. NZ6Z2C011B) caused this code.
   Typical fix: Repair the damaged section of the wiring harness or clean/replace the affected connector. In one documented case, a wheel speed sensor harness had to be replaced.
   Est. part cost: $20-$250

Rare But Worth Checking

• Rodent Damage to Wiring:

Diagnosis Steps

1. Connect a professional-grade scan tool (like Ford's FDRS) capable of reading codes from all vehicle modules (PSCM, ABS, IPMA).
2. Check for Technical Service Bulletins (TSBs) related to U0415 for the 2022 Maverick. Specifically look for SSM 51437 and SSM 50771.
3. Scan all modules and document all stored DTCs. Note if C0051:67 and U0418:86 are present, as this strongly suggests the software issue.
4. If the vehicle was built on or before March 23, 2022, follow the TSB recommendation to update the Power Steering Control Module (PSCM) software. This is the most likely fix.
5. If the code returns or the TSB does not apply, thoroughly test the 12V battery under load and check the vehicle's main power and ground connections for tightness and corrosion.
6. Visually inspect the wiring harnesses and connectors for the ABS module and all four wheel speed sensors. Look for any damage, corrosion, or signs of rodent activity.
7. If a specific wheel speed sensor code is present (like C003A), inspect that sensor's wiring harness more closely for an open or short.
8. If all other steps fail, further diagnostics on the ABS module itself are required, which may lead to its replacement and reprogramming.

Related Codes That Often Appear With This One

• C0051:67 — This code for 'Steering Wheel Position Sensor - Signal is Invalid' is stored in the ABS module and is explicitly mentioned alongside U0415 in Ford's TSBs SSM 51437 and SSM 50771, indicating they are part of the same underlying software issue. The ':67' suffix indicates the signal is incorrect after an event.
• U0418:86 — This code, 'Invalid Data Received From Brake System Control Module A', is often stored in the Image Processing Module A (IPMA) and is also cited in the same TSBs, pointing to the same network-wide communication fault originating from the PSCM software bug. The ':86' suffix indicates an invalid signal was received.

Technical Service Bulletins (TSBs) & Recalls

• SSM 51437: Supersedes SSM 50771. For vehicles built on or before 23-Mar-2022, this TSB addresses various warning messages like 'Pre-Collision Assist Not Available' accompanied by DTCs U0415:00 (in PSCM), C0051:67 (in ABS), and U0418:86 (in IPMA). It identifies a software issue in the PSCM and directs technicians to update it using FDRS.
• SSM 50771: An earlier TSB for the same s

Platform-Specific Known Issues

• A known issue on 2022 Ford Mavericks built on or before March 23, 2022, involves multiple warning messages (Pre-Collision Assist, Cruise Control) appearing due to a communication breakdown between control modules. Ford Technical Service Bulletin SSM 51437 directly addresses this scenario, where the Power Steering Control Module (PSCM) logs U0415 because of invalid data from the ABS module. A forum user on MaverickTruckClub confirmed that a dealer visit for U0415 resulted in 'a bunch of software updates' that resolved the issue. Another user in the same forum traced their issue to a faulty rear wheel speed sensor harness, providing a specific part number for the repair.

Mechanic-Grade Diagnostic Values

• CAN Bus Network Resistance — expected: Approximately 60 Ω. Failure: A reading of 120 Ω indicates an open circuit or that one of the two terminating resistors is offline. A reading significantly less than 60 Ω can indicate a short in the wiring.
• CAN Bus Voltage (Key On) — expected: CAN_H: ~2.6V to 3.5V; CAN_L: ~2.4V to 1.5V (referenced to ground).. Failure: Voltages that are stuck high, low, or at 0V indicate a short to power, short to ground, or an open circuit.

Hidden / Shadow Codes Worth Checking

• U0415:00: The ':00' failure type code indicates 'No Sub Type Information'. It's a general flag from the PSCM that it received invalid data from the ABS module. (see via Ford Diagnosis and Repair System (FDRS) or other professional-grade scan tools.)
• C0051:67: The ':67' failure type code indicates 'Signal is incorrect after event'. This is logged in the ABS module regarding the steering wheel position sensor, often in conjunction with the main U0415 fault. (see via Ford Diagnosis and Repair System (FDRS) or other professional-grade scan tools.)
• U0418:86: The ':86' failure type code indicates 'Signal Invalid'. This is logged in the Image Processing Module (IPMA) when it receives invalid data from the brake module, as part of the cascade failure. (see via Ford Diagnosis and Repair System (FDRS) or other professional-grade scan tools.)

Scan Tool Commands That Help

• Ford Diagnosis and Repair System (FDRS): Programmable Module Installation (PMI) — This function is required when replacing a control module, such as the ABS module. The PMI process downloads the vehicle-specific configuration data (known as 'As-Built' data) from Ford's servers and programs it into the new module to ensure it works correctly with the other systems on the vehicle.
• Ford Diagnosis and Repair System (FDRS): Module Reprogramming / Software Update — This is the specific function required to perform TSB SSM 51437. It checks for and installs the latest software/firmware for a specific module, such as the PSCM, which is the primary fix for this code on early-build 2022 Mavericks.
• Ford Diagnosis and Repair System (FDRS): ABS Module Self-Test — After checking for codes and TSBs, running the module self-test can help verify the internal functionality of the ABS module and check for other related faults that may not have set a primary DTC.

Wiring & Ground Locations

• Passenger Footwell Grounds — In the passenger footwell, there are two threaded ground bolts on the firewall just under the Body Control Module (BCM) and fusebox.. The BCM is a major hub for multiple communication networks. A poor ground at this location can cause a wide range of communication DTCs, including U-codes.
• Rear Cabin Grounds — Behind the rear seat, there are several factory ground points on the body structure, often used for audio equipment or other accessories.. These grounds are near the 12V battery location on Hybrid models and serve various rear-body electronics. Verifying they are clean and tight is part of a complete electrical check.
• Engine Compartment Grounds — There are several ground points in the engine compartment, with some easily accessible on top of the frame rails.. The ABS module and PSCM are located in the engine bay. Ensuring their primary ground connections are secure is critical for preventing data corruption and communication faults.
• ABS Module Connector C135 — This is the main electrical connector at the ABS control module itself.. This connector contains the power, ground, and CAN bus high/low circuits for the module. Pin 12 (White/Blue) is the HS-CAN High and Pin 25 (White) is the HS-CAN Low on a representative diagram. Checking for corrosion or backed-out pins here is a key diagnostic step.

Real Owner Repair Stories

• Reddit user on r/MachE (2024 Ford Mustang Mach-E (Shares similar electronic architecture)) — Daily, repeated "Pre-collision Assist Not Available" and "Front Camera Fault" messages, flooding the FordPass app with notifications.
  ❌ Tried (didn't work) Repeatedly restarting the vehicle, scheduling dealer visits.
  ✅ What actually fixed it The front camera, located in the rearview mirror housing, had become physically loose in its mounting bracket. The owner added layers of duct tape to the retaining clip to create more tension, securing the camera firmly in place. This completely resolved the error messages.

Model Year Variations Within This Range

• 2022 (Early Production): Vehicles built on or before March 23, 2022, are specifically called out in TSB SSM 51437 as being prone to the software issue that causes U0415, C0051:67, and U0418:86. The fix is a PSCM software update. Vehicles built after this date likely have the updated software from the factory, making this specific cause less likely.
