If you have a 2006-2018 Dodge RAM, Chevy, or GMC truck with an ABS light on your dash, you most likely have a faulty ABS module. These modules are known as the TRW EBC-440, and they play a crucial part in your vehicle’s safety by controlling the Anti-Lock Braking System. They can be found on Dodge RAM, Chevy Silverado, and GMC Sierra trucks, along with a few other applications. Unfortunately, these modules frequently fail, with common symptoms including loss of communication, the ABS pump being stuck on, an ABS light, and pump codes such as code C2200. These issues should not be ignored, as a non-functional ABS system can potentially cause you to lose control of the vehicle. We’ll walk through how these modules work, why this happens, and the best solution to get your vehicle back up and running smoothly again.

How Does an ABS Module Work?

The ABS module is responsible for controlling the braking pressure to your vehicle’s individual wheels. It processes the data it receives from the wheel speed sensors to detect when a wheel is about to lock up and start skidding. When a potential slip is detected, it releases braking pressure and begins to pulse the brakes rapidly, preventing the wheels from locking up. This function is vital for maintaining vehicle stability, especially on slick roads or in emergency braking scenarios.

The ABS module isn’t seen in action on a daily basis. It is often only in extreme scenarios that you’ll experience the “chattering” of your anti-lock braking system. However, these modules are constantly at work, ensuring your safety and peace of mind. When an ABS light comes up on your dash, it is signaling that there’s an issue needing immediate attention.

What Causes a RAM ABS Module to Fail?

ABS module failure is unfortunately a common problem for many vehicles. Here are some of the most common causes:

1. Electrical Failures

Electrical issues such as short circuits or damaged wiring can be a leading cause of ABS module failure. These problems disrupt communication between the ABS module and other vehicle components, preventing the ABS from functioning correctly.

2. Software Issues or Glitches

Sometimes, ABS module failures are not caused by hardware issues but rather by software glitches. Corrupted software within the module can cause the system to malfunction, leading to inconsistent operation or failure codes.

3. Wear and Tear

Like any other part, ABS modules are subject to wear and tear. Over time, they may develop weakened internal connections, degraded components, or general malfunctioning that can cause the module to fail.

Symptoms of a Bad ABS Module

Symptoms can vary based on the specific vehicle – especially diagnostic trouble codes – but in general, common signs of a failing ABS module include:

• ABS light on your dashboard – This is often the first indicator of a problem and the easiest to spot. This does not necessarily point directly to the ABS module, but should lead you to troubleshoot further.

• Loss of Communication – You’ll need a scan tool to check this one, but if you’re unable to establish communication with the ABS module, it’s a strong indicator that the problem is related to the module itself and not another part of the system.

• ABS Pump Stuck On – If the ABS pump is constantly running or doesn't turn off, it could be a sign that the module has failed.

• ABS Pump Codes – These codes will vary based on the vehicle manufacturer, so it is important to carefully research what the codes mean before jumping to conclusions.

• Intermittent Functionality – If any of the symptoms mentioned are intermittent, it’s likely either a wiring issue or an ABS module failure.

How to Repair a Dodge RAM ABS Module

If you suspect that your ABS module is malfunctioning, you might have a few options. It’s possible that there may be a brand-new replacement available for your vehicle. This often depends on how old the vehicle is and if the manufacturer still offers the part. The biggest downside is that these parts can often be very expensive and will likely require programming to be compatible. In addition, there might be long lead times and hefty installation and programming costs. The other option is to repair your existing module. Because of the complexity of this circuitry, DIY repairs often fall short when it comes to ABS modules. However, at Circuit Board Medics we’ve developed a solution to rebuild your module to OEM standards or better.
