ABS Diagnostics FAQS

What causes a trailer ABS light to come on?

The ABS light coming on may be normal functionality, or it can indicate a problem. When the key is inserted and the system is powered up, the ABS system should trigger the ABS light in the dashboard for a brief period. This indicates that the system has powered up and that there are no error conditions. In some trucks, the light may only come on when the trailer is first plugged in.

However, if the system powers up and the light does not go off after a few seconds, it could indicate there is a problem with the brakes. This is also a likely case if the light ever comes on and stays on while driving. In cases like this, the system will need to be inspected and the problem diagnosed.

What is the most common problem with ABS systems?

ABS systems are subjected to incredible amounts of dirt and debris. This can cause poor connections from the pins in the plug, which will result in inconsistent power and unpredictable operation. Another very common ABS problem is the module itself. The module is the part of the ABS that processes the braking conditions constantly, as well as conditions supplied by speed and wheel sensors. This module can become damaged by debris created by the braking process.

How much does it cost to fix ABS?

Depending on what repair work your truck or trailer needs, the price can fluctuate considerably. For minor problems that can be solved with cleaning, you may only spend $100 – $200. However, if the problems point to the ABS module needing to be replaced, that could cost $1,000 or more depending on the module that your truck needs.

How long should an ABS module last?

It isn’t uncommon to have an ABS module need replacement after 10 to 15 years, but it is also possible that your rig may need one after just 100,000 to 200,000 miles. The best way to ensure that your ABS module is still performing properly is to make sure that you test it often and keep a close eye out for problems.

How do you diagnose ABS problems?

The most common way that a truck driver or owner-operator can potentially diagnose ABS problems on their own is to stay aware of any changes in brake performance and watch for symptoms of a failing ABS module. A major indicator is brake pedals failing to respond with the same amount of force or even locking up while in use. The failing module will cause erratic operation.
