2022-2024 Ford Maverick Towing Module: Decoding Failures, Recalls, and Programming

Known Issues: Major Software Recall

A significant issue affecting 2022-2026 Ford Mavericks is a widespread recall for the Towing Control Module. Under NHTSA Campaign Number 26V104000 (Ford reference 26C10), a software fault can cause the module to lose communication with the vehicle, typically at startup. This failure can lead to inoperable trailer brake lights, turn signals, and a complete loss of trailer braking function.

Drivers will typically see a "Trailer Brake Module Fault" message on the instrument cluster, often accompanied by a rapidly flashing turn signal indicator on the dash and a "Blind Spot Assist System Fault" warning. The remedy for this recall is a software update performed by a Ford dealer or through an over-the-air (OTA) update. The software fix for 2022-2024 Mavericks was made available around June 2026.

Symptoms of a Failing Towing Control Module

Aside from the specific recall symptoms, a failing towing module can present several other issues. Recognizing these signs can help you diagnose a problem before it becomes a major safety risk.

• No Trailer Lights or Intermittent Lights: One of the most common signs is when your trailer's turn signals, brake lights, or running lights don't work at all, even though the truck's lights function normally.
• "Trailer Disconnected" or "Trailer Brake Module Fault" Message: The dashboard may display a persistent warning that a trailer is disconnected (even when it's plugged in) or a fault with the module itself.
• No Trailer Brake Activation with Pedal: You might find that the trailer brakes engage when you manually squeeze the brake controller's lever, but not when you press the brake pedal.
• Inability to Adjust or Save Brake Gain: The in-dash brake controller may fail to store your gain settings or not display the gain level on the instrument panel.
• Rapidly Flashing Turn Signal Indicator: When you activate a turn signal, the indicator on the dashboard may flash twice as fast as normal, which is often a sign the system doesn't detect the trailer's light bulb.
• Disabled Auto Start/Stop Feature: In some cases, a faulty module can trick the truck into thinking a trailer is always connected, which may disable the Auto Start/Stop system.

These symptoms can sometimes be caused by issues with the trailer's wiring or a bad ground connection, so it's important to test with a known-good trailer to confirm the problem is with the truck.

Programming and Installation: FORScan or Dealer Required

Replacing a Towing Control Module in a Ford Maverick is not a simple plug-and-play operation. The new or used module must be programmed to the vehicle's specific configuration to function correctly.

FORScan is a powerful software application that runs on a Windows laptop and connects to the vehicle's OBD-II port via a specific adapter. It allows users to access and modify module configuration data, known as "as-built" data. When installing a replacement module, the as-built data from the original module should be copied and written to the replacement. If the original data is not available, the configuration for the factory tow package must be enabled in the Body Control Module (BCM) and other related modules. Without this step, the truck will not recognize the module, and you will likely experience the same faults as with a failed unit.

Buying a Used Towing Control Module for Your Maverick

Given the high cost of a new OEM module, a used unit from a reputable recycler is an excellent value. However, there are critical factors to consider to ensure you get a compatible and functional part.

Compatibility Check

The most important step is to match the part number. The engineering part number is printed directly on the module's label. Common part numbers include NZ6T-19J294-AB, NZ6T-19J294-AC, NZ6T-19J294-AD, and NZ6T-19J294-AE. While these may supersede each other, it's safest to match your original number exactly. The service part number, often sold as a kit, is NZ6Z-19H332-A. Crucially, you must source a module from a Maverick that was equipped with the factory tow package. Modules from base model trucks without this option will not work.

Physical Inspection

When you receive the used module, inspect it carefully. Check for any signs of physical damage, like a cracked case or broken connector tabs. Look closely at the electrical connector pins for any corrosion or evidence of water intrusion, which can cause intermittent failures.

Why Used OEM is the Best Choice

For a complex electronic part like this, a used OEM module is almost always superior to a new aftermarket alternative (if one is even available). The OEM module is designed to integrate perfectly with the Maverick's other computer systems. Aftermarket modules can create communication errors, leading to frustrating and hard-to-diagnose electrical gremlins. A used OEM module that has been properly tested is the most reliable and cost-effective solution.
