2015-2017 Challenger & 300 ABS Module Failure: Fixing Warning Lights and Programming a Replacement

Symptoms of a Failing ABS Module

When the ABS module in a 2015-2017 Chrysler 300 or Dodge Challenger begins to fail, your dashboard will almost certainly let you know. The failure disables key safety features, so the instrument cluster displays multiple warnings.

• ABS, ESP, and BAS Warning Lights: The most common symptom is the illumination of the Anti-Lock Brake (ABS), Electronic Stability Program (ESP), and/or Brake Assist System (BAS) warning lights on your dashboard. Often, these lights will come on simultaneously.
• "Service ABS System" Message: A message may appear in the instrument cluster information display.
• Unresponsive or Spongy Brake Pedal: In some cases, the brake pedal may feel different, either requiring more effort to press or feeling soft and unresponsive.
• Wheels Locking Up: The primary job of ABS is to prevent your wheels from locking and skidding during a hard stop. If the module has failed, your wheels may lock up, increasing stopping distance and causing a loss of steering control, especially on wet or slippery surfaces.
• Inaccurate Speedometer: In rare instances, a failing ABS module can cause the speedometer to behave erratically or stop working altogether, as it relies on data from the wheel speed sensors.

Common Diagnostic Trouble Codes (DTCs)

A professional OBD-II scanner that can read ABS system codes is essential for proper diagnosis. The most common code pointing to a bad module is:

• C2200 - ABS Module Internal Failure: This code specifically indicates an internal fault within the electronic control module itself. It can also be triggered by a VIN mismatch after a used module has been installed without proper programming.
• U0121 - Lost Communication With ABS Module: This code means other computers in the vehicle, like the Powertrain Control Module (PCM), can no longer communicate with the ABS module.

While other codes related to wheel speed sensors (e.g., C1233) or the pump motor (e.g., C0110) can appear, the C2200 code is the strongest indicator that the module itself needs replacement.

Programming: The Most Critical Step for Replacement

This is not a plug-and-play part. Whether you install a new or used ABS module, it must be electronically configured to your vehicle's specific Vehicle Identification Number (VIN) and options. Failure to do so will result in a VIN mismatch error (C2200 code), and the ABS and stability control systems will not function. This process is typically called "ABS Initialization." You have three main options to get this done:

1. Dealer or Independent Shop

A Chrysler/Dodge dealership or a well-equipped independent shop can perform the ABS initialization using the factory wiTECH scan tool. This is the most straightforward but often most expensive option. The programming itself typically costs about one hour of shop labor.

2. DIY with AlfaOBD

For the technically savvy DIYer, it is possible to program the module yourself. This requires a specific software and hardware combination:

• AlfaOBD Software: A powerful diagnostic software for FCA vehicles that runs on a Windows PC or Android device.
• OBD-II Interface: A compatible adapter like an OBDLink MX+ to connect your device to the car.
• Security Gateway Bypass: For 2018+ models this is required, and may be needed on some 2017 models to allow the software to make changes.

Using AlfaOBD, you can connect to the ABS module, perform the "ABS Initialization" routine, and write your car's VIN to the replacement module. This clears the mismatch codes and allows the system to function correctly.

3. Mail-In Programming Service

Several companies offer mail-in services where you send them your replacement module (and sometimes your original failed module). They will either clone the data from your original module to the replacement or program the replacement with your vehicle's VIN. The module is then shipped back to you, ready to be installed without needing further programming. This is a good middle-ground option if you want to do the physical installation yourself but don't want to invest in diagnostic software.

Buying a Used ABS Control Module

Given the high cost of a new OEM module, a used unit from a reputable recycler is an excellent value. Since these modules are sensitive electronics, here’s what to look for:

• Verify the Part Number: Match the OEM part number exactly. Several part numbers were used for these vehicles. Known numbers include 68316593AD, 68258644AA, 68266996AA, 68291563AA, and 68341606AB.
• Check Compatibility Warnings: This is crucial. Pay close attention to two specific fitment rules:
  • No Adaptive Cruise Control: Most commonly available used modules are for vehicles without adaptive cruise control. Ensure the donor vehicle's options match yours.
  • 2015 Dodge Challenger Date Split: For the 2015 Challenger, part number 68258644AA is only for vehicles built on or after April 28, 2015.
• Inspect for Damage: Check the electrical connector pins for any signs of corrosion or damage. Ensure the plastic housing isn't cracked and the mounting points are intact.
• Low Mileage is a Plus: While not a guarantee of longevity, a module from a lower-mileage vehicle is generally preferable.

Replacement Cost Comparison

Prices can vary, but here is a general breakdown of what to expect for the part and labor.

Known Issues, TSBs, and Recalls

As of early 2026, there are no specific recalls issued by the NHTSA for widespread failure of the ABS control module on 2015-2017 Chrysler 300 or Dodge Challenger models.

However, there was a major recall (NHTSA Campaign 18V332000) that affected these and many other FCA vehicles. This recall was for a software issue that could prevent the cruise control from disengaging. The fix involved a software update to the Powertrain Control Module (PCM), not the ABS module. If you are experiencing issues, it is always wise to check if your vehicle has had all open recalls completed.
