2019-2024 Ram 1500 ABS Module: Recall, Programming, and Part Number Guide
This guide covers the critical software recall, mandatory programming, and how to choose the correct used ABS module for your 5th Generation Ram 1500.
- A replacement ABS module MUST be programmed to your truck's VIN, it is not plug-and-play.
- Verify your part number matches EXACTLY, as Ram uses many different modules based on vehicle options.
- This part fits the 2019-2024 'New Body Style' (6-lug wheels), not the 'Classic' model (5-lug wheels).
- Check if your truck is affected by NHTSA Recall 24V-653, as a free dealer software update may fix the issue.
Compatibility Warning: New Body Style (DT) vs. Ram Classic (DS)
Warning: This guide applies ONLY to the 2019-2024 Ram 1500 'New Body Style' (also known as the 5th Generation or 'DT' platform). It WILL NOT fit the Ram 1500 'Classic' (also known as the 4th Generation or 'DS' platform), which was sold alongside the new model. Parts are not interchangeable between these two different trucks.
The easiest way to tell them apart is to check the wheels: the 2019-2024 new body style has six-lug wheels, while the Ram 1500 Classic has five-lug wheels. Always confirm your truck's style before purchasing parts.
Symptoms of a Failing Ram 1500 ABS Module
A failing ABS module will almost always make its presence known through multiple warning lights on your dashboard. Because the module is tied into several vehicle systems, a single failure can have a cascading effect.
- ABS Warning Light: This is the most common and direct symptom.
- Traction Control / ESC Light: The Electronic Stability Control (ESC) light will illuminate, indicating the system is disabled.
- 'BRAKE' Warning Light: The main red brake warning light may also come on.
- Loss of Related Safety Features: You will likely see messages for 'Service Electronic Braking System,' 'Service Antilock Brake System 🎬 See how to troubleshoot the Service Antilock Brake System warning.,' and features like Adaptive Cruise Control (ACC) and Forward Collision Warning (FCW) will become unavailable.
- Inaccurate or Dead Speedometer: In some cases, the speedometer may stop working because it relies on data from the wheel speed sensors, which is processed by the ABS module.
- Unusual Brake Pedal Feel: The brake pedal may feel hard or stiff, or the ABS may seem to activate incorrectly under light braking.
Common Diagnostic Trouble Codes (DTCs)
If you scan your vehicle with an OBD-II scanner, you may find one or more of the following codes, which strongly point to a faulty ABS module:
- C2200 - Anti-Lock Brake Module Internal Electronic Fault 🎬 Watch: Diagnosing the common C2200 internal electronic fault code.
- U0121 - Lost Communication With ABS Control Module
- C2116 - Pump Motor Fault / Pump Supply Low Voltage
- C2202 - Original VIN Mismatch (This code appears after a replacement module is installed but before it has been programmed).
Major Software Recall (NHTSA 24V-653)
In September 2024, Chrysler (FCA US, LLC) issued a massive recall for approximately 1.2 million 2019 and 2021-2024 Ram 1500 trucks. The recall, identified as NHTSA campaign number 24V-653, addresses a software malfunction within the ABS control module that can disable the Electronic Stability Control (ESC) system, increasing the risk of a crash.
The remedy for this recall is a simple software update performed by a Ram dealer, free of charge. Before replacing your module, it is essential to check if your vehicle is part of this recall, as the software update may resolve your issues. You can check your vehicle's VIN on the NHTSA website (nhtsa.gov/recalls).
Buying a Used ABS Control Module for Your Ram 1500
Due to the high cost of new units, a quality used OEM ABS module is often the best value. However, there are critical rules to follow to ensure you get a part that will work for your truck.
1. The Part Number MUST Match EXACTLY
This is the most important rule. Ram uses many different ABS modules depending on the truck's specific features, such as air suspension, adaptive cruise control, axle ratio, and trailer brake control options. Even if a module looks identical, if the part number is different, it will not work correctly. The only way to guarantee compatibility is to physically inspect your truck's original module and match the OEM part number (e.g., 68436003AD) to the used part you are buying.
2. Physical Inspection
When inspecting a used module, look for:
- No Corrosion: Check the aluminum housing and the electrical connector pins for any signs of white, crusty corrosion. Water intrusion is a common cause of failure.
- Intact Connectors: Ensure the large electrical connector and its locking tab are not cracked or broken.
- Cleanliness: The part should be reasonably clean. Excessive dirt or grease could indicate it came from a poorly maintained or damaged vehicle.
3. Why Used OEM is a Smart Choice
For a complex electronic part like this, a used OEM module is often superior to a new aftermarket one. A used OEM part was designed and programmed by the manufacturer to work with your truck's systems. As long as the part number matches, you can be confident it is the correct hardware. Aftermarket modules can have software and communication issues, even after programming.
Programming and Installation Requirements
Critical: A replacement ABS module—whether new or used—MUST be programmed to your vehicle's Vehicle Identification Number (VIN) after installation. It is not a 'plug-and-play' part.
This process is often called 'ABS Initialization.' It allows the new module to learn your truck's specific configuration and communicate with the other computers. If you install a module without programming it, you will get a VIN mismatch fault code (like C2202) and the warning lights will remain on.
Who Can Program the Module?
- Ram Dealership: This is the most reliable option. They have the correct diagnostic tools (wiTECH) and access to vehicle software. However, be aware that some dealerships may refuse to install or program a used part supplied by a customer.
- Independent Repair Shop: A well-equipped independent shop that specializes in diagnostics or works on Chrysler/Ram vehicles may have the necessary high-end scan tools and software subscriptions to perform the initialization.
- Advanced DIY (AlfaOBD): Some owners have successfully programmed used modules using advanced diagnostic software like AlfaOBD paired with a compatible OBD-II adapter. This requires technical skill and is not recommended for beginners.
Pro Tip: You can often replace just the electronic control module without opening the hydraulic brake system. The module is typically held onto the hydraulic control unit (HCU) with four Torx screws. By carefully swapping only the electronic portion, you avoid the need to bleed the brakes, which simplifies the job significantly.

Frequently Asked Questions (FAQ)
Can I drive my Ram 1500 with a bad ABS module?
Yes, but with significant risks. Your standard hydraulic brakes will still function, but you will not have anti-lock brakes (ABS), electronic stability control (ESC), or traction control. This means your wheels can lock up during a hard stop, increasing the risk of skidding and losing control, especially on wet or slippery roads. It is recommended to have the system repaired as soon as possible.
Will a used ABS module from the same year truck work without programming?
No. Even if the module comes from an identical truck, it is coded to the original vehicle's VIN. It must be reprogrammed to your truck's VIN to function correctly and clear the dashboard warning lights.
Where is the ABS module located on a 2019-2024 Ram 1500?
The ABS module and pump assembly is located in the engine bay on the driver's side, below the main fuse box (Totally Integrated Power Module). Accessing it typically requires removing the driver's side front wheel and the fender liner.
What's the difference between the ABS module and the ABS pump?
The assembly consists of two main parts that are bolted together: the electronic ABS control module (the computer) and the hydraulic ABS pump/HCU (the valve block with the motor). Often, only the electronic module fails. As mentioned in the 'Pro Tip' above, you can sometimes replace just the electronic part without disturbing the brake lines.
