Common Issues of 2018 RAM 2500 ABS Module

The ABS module in your 2018 RAM 2500 is a complex and crucial component that plays a vital role in maintaining stability and control during braking. Like any other part, it can develop issues over time, affecting the overall performance of the ABS system. Here are some common issues that you may encounter with the ABS module in your 2018 RAM 2500:

Faulty Wheel Speed Sensor

Wheel speed sensors are responsible for sending information about each wheel’s rotational speed to the ABS module. A faulty or damaged wheel speed sensor can cause the ABS module to receive inaccurate data or no data at all, leading to improper functioning of the ABS system. 

Symptoms of a faulty wheel speed sensor include the ABS warning light coming on, irregular braking behavior, or reduced braking performance.

Corroded or Damaged Electrical Connections

The ABS module relies on electrical connections to receive data from sensors and control the hydraulic control unit. Over time, these connections can become corroded or damaged, resulting in intermittent or complete loss of communication between the ABS module and other components. 

This can lead to the ABS system not functioning as intended, triggering the ABS warning light or causing erratic braking behavior.

Internal Component Failure within the ABS Module

The ABS module contains various electronic components and circuitry that can wear out or fail over time. This may result in a range of issues, from intermittent ABS function to complete failure of the ABS system. In some cases, the ABS module may need to be replaced to restore proper ABS functionality.

Malfunctioning Hydraulic Control Unit

The hydraulic control unit receives commands from the ABS module to modulate brake pressure and prevent wheel lockup. If the hydraulic control unit is not functioning correctly, the ABS system may not be able to regulate brake pressure effectively,

Leading to reduced braking performance and the risk of wheel lockup. This can manifest as a pulsating brake pedal or the ABS warning light illuminating.

Damaged or Leaking Brake Lines

The brake lines connected to the ABS module are responsible for delivering brake fluid to the brakes. Damaged or leaking brake lines can compromise the brake fluid pressure, affecting the ABS system’s ability to function correctly. In this case, you may notice a spongy or unresponsive brake pedal or a decrease in braking performance.

If you experience any of these common issues with your 2018 RAM 2500 ABS module, it’s crucial to address the problem promptly to ensure the safety and performance of your vehicle. In some cases, simple troubleshooting and repairs can resolve the issue, while in other instances, you may need to consult a professional mechanic for further diagnosis and assistance.
