Solving the Mystery: What to Do When Your ABS and Traction Control Lights Turn On After a Brake Job

The ABS and Traction Control lights should be reset by a certified mechanic after a brake job is completed.

Abs And Traction Control Light On After Brake Job

When youve just had a brake job done and your ABS and traction control lights suddenly come on, it can be a bit confusing and perplexing. However, theres usually a straightforward answer: some of the connecting parts related to the brakes were not installed correctly or fastened tight enough. This might be because they were dislodged while your vehicle was being worked on, such as when a brake caliper was removed or the wheels were spun off. Luckily, the problem can usually be fixed quickly and cheaply just by making sure all the parts are properly secured. Furthermore, in some cases, it may be necessary to reset any error codes triggered by the episode – which can often simply be done via a software update. In any case, if your ABS and traction control lights keep coming back on after a brake job has been performed, its important not to ignore it but instead have a skillful technician investigate further.

Common Causes of ABS and Traction Control Light Coming On After Brake Job

The ABS (Anti-lock Braking System) and Traction Control Light can come on after a brake job for various reasons. The most common causes include a leaking hydraulic system, faulty wheel speed sensor, poor quality of parts used, and air trapped in the ABS system.

Diagnosis of ABS and Traction Control Light After Brake Job

To diagnose the issue, it is important to first perform a differential voltage test to check the voltages at the wheel speed sensors. It is also important to verify the parts used during the brake job to make sure that they are of good quality and are not causing any issues. A visual inspection of all components should also be conducted to ensure that everything is functioning properly.

Repairing the ABS and Traction Control After Brake Job

Once any issues have been identified, it is important to fix them as soon as possible in order to ensure safety while driving. Leaks should be detected and restored in order for the hydraulic system to work properly. If necessary, the wheel speed sensor should be replaced or cleaned to ensure proper functionality. Finally, it is important to bleed the ABS system in order to remove any air that may have been trapped during installation.

Common Causes Of Abs And Traction Control Light On After Brake Job

One of the most common causes of the ABS and traction control light coming on after a brake job is an incorrect installation of the brake pads. If the brake pads are not installed properly, they may not be making full contact with the rotors, resulting in poor braking performance. Additionally, incorrect installation can lead to damage or wear to the caliper pistons, which can cause a misalignment of the brakes and trigger the ABS and traction control light.

Another common cause is that when replacing a brake rotor, it’s possible that debris inside the rotor can damage or restrict the flow of brake fluid through the system. This can create an imbalance in pressure, causing your ABS system to kick in and triggering a warning light.

What To Do If The Abs And Traction Control Light Is On After A Brake Job

If your ABS and traction control light comes on after a brake job, it is important to have it checked as soon as possible by a qualified mechanic. It is important to determine why it came on so that any necessary repairs can be made before further damage occurs to your brakes.

The first step is to check for any visible signs of wear or damage on your brakes. Look for any signs of leaking fluid or corrosion around the calipers or rotors. If everything looks ok visually, then you should have your brakes inspected by a professional mechanic who will be able to inspect them more thoroughly and diagnose any potential problems with your brakes.

How To Troubleshoot An Abs And Traction Control Light On After A Brake Job

If you have determined that there are no visible signs of damage or wear on your brakes, then you should start troubleshooting by checking all components involved in braking system. Start by inspecting all connections between each component such as calipers, hoses, lines and sensors for any signs of damage or loose connections which may be causing an issue with your braking system.

Next you should check for blockages in any lines or hoses connected to your braking system. Any debris which has built up inside these lines could restrict fluid flow and cause an imbalance in pressure within the system which could trigger an ABS warning light.

Finally you should check for any fault codes being stored within your vehicle’s computer memory using an OBDII scanner tool which will help identify what issue is causing your ABS light to come on after a brake job has been completed. Armed with this information you can then determine what repairs need to be made in order to rectify the problem so that you can get back out on the road safely again without worrying about any further issues arising due to faulty brakes or faulty components within your braking system.

FAQ & Answers

Q: What are the common causes of ABS and traction control light coming on after brake job?

A: Common causes of ABS and traction control light coming on after brake job include leaking hydraulic system, faulty wheel speed sensor, poor quality parts used and air trapped in the ABS system.

Q: What is a differential voltage test?

A: A differential voltage test is used to diagnose an ABS or traction control system. It involves measuring the amount of voltage from each wheel speed sensor to determine if there is a fault or discrepancy in any of the sensors.

Q: How is a leaking hydraulic system repaired?

A: Leaks in the hydraulic system can be detected and repaired by performing a visual inspection. This can help locate the source of the leak and allow for any necessary repairs to be made.

Q: How should faulty wheel speed sensors be replaced?

A: Faulty wheel speed sensors should be replaced with new ones that meet the manufacturer’s specifications. Additionally, they should be cleaned or replaced as necessary to ensure they are working properly.

Q: How do you bleed an ABS system?

A: Bleeding an ABS system involves using a special tool to pump new brake fluid into the lines while simultaneously opening and closing valves in order to expel any air bubbles that may have become trapped in the lines. This process should only be done by an experienced technician in order to ensure it is done correctly.

The cause of the ABS and traction control light coming on after a brake job is most likely due to a faulty part or incorrect installation. It is important to inspect all parts and ensure that they are properly installed for the best performance. If the issue persists, it is likely that a professional should be consulted in order to repair the issue.
