2013-2019 Taurus, MKS, Flex, MKT & Police Interceptor AWD Module Guide

Is This the Body Control Module (BCM)?

It's important to clarify a common point of confusion. While this part is an electronic control module, it is not the main Body Control Module (BCM). The BCM is a different computer that controls interior and exterior electrical components like power windows, door locks, and lights. The part covered in this guide is specifically the All-Wheel Drive (AWD) Control Module, sometimes referred to by Ford as the Transfer Shift Control Module or Differential Control Module. Its only job is to manage the AWD system.

Symptoms of a Failing AWD Control Module

When the AWD module begins to fail, the vehicle will typically alert the driver through messages on the instrument cluster and disable the AWD system as a precaution. You may experience one or more of the following symptoms:

• "AWD OFF" or "AWD FAULT" Message: This is the most common and direct indicator of a problem within the system.
• Warning Lights: The traction control light, ABS light, or a wrench icon may illuminate on the dashboard.
• Loss of All-Wheel Drive: The vehicle may revert to front-wheel drive only, which can be especially noticeable during acceleration on slippery surfaces.
• Communication Issues: A complete failure of the module can lead to a "no communication" error when a diagnostic scan tool is connected.

Common Diagnostic Trouble Codes (DTCs)

A professional scan tool can retrieve codes that point directly to a faulty module or related components. Some codes associated with AWD module failure include:

• U0121: Loss of communication with ABS module.
• U1900: CAN communication bus fault.
• B1342: ECU defective.
• C0095, C05D9, C05E8: These codes may indicate an issue within the AWD module on some Ford platforms.

Programming and Calibration: The Most Critical Step

Replacing the AWD module requires a mandatory programming step to sync it with your vehicle's Vehicle Identification Number (VIN) and other onboard systems. This process ensures the module communicates correctly with the Powertrain Control Module (PCM) and ABS module.

There are two main programming methods:

1. Programmable Module Installation (PMI): This is the preferred method. A technician uses a diagnostic tool to download the configuration data from your old, original module and uploads it to the new one. This is only possible if the old module can still communicate.
2. As-Built Data: If the original module is completely dead, a technician must program the new module using "As-Built" data. This is the original configuration file for your vehicle's specific VIN from the factory.

This programming can be performed by a Ford/Lincoln dealership or a well-equipped independent repair shop that has the Ford Diagnostic and Repair System (FDRS) software or a compatible high-end scan tool. Some advanced DIY mechanics may be able to perform this programming with tools like FORScan, but it requires technical expertise.

Buying a Used AWD Control Module

A used OEM module is a cost-effective and reliable alternative to a new part, provided you take the right precautions. Since the hardware is generally robust, the main concern is ensuring the part is in good condition and compatible.

What to Inspect:

• Match the Part Number: It is critical to match the OEM part number exactly. The primary part numbers for this module are DG1Z-7E453-CA and the corresponding Motorcraft number TM-254. Other compatible numbers may include DG1A-7H473-CA and DG1A-7H473-CB.
• Check for Corrosion: Carefully inspect the electrical connector pins for any signs of green or white corrosion. This is a sign of water intrusion, which is a common cause of electronic module failure.
• Examine the Case: Look for any cracks, swelling, or signs that the case has been pried open. A damaged case could indicate internal damage.
• Plan for Programming: Before you buy, have a plan for who will program the module. Confirm with your local dealership or independent shop that they are willing and able to program a customer-supplied used module.

Cost to Replace the AWD Control Module

The cost of replacement can vary significantly based on the price of the part and local labor rates. Programming costs are typically included in the labor estimate when performed at a repair shop.
