Why Are Jeep Wrangler Abs And Traction Control Light On? – Meaning And Problem

What Is The Reason For Jeep Wrangler Abs And Traction Control Light On?

Jeep Wrangler owners may have noticed the ABS and traction control lights on their dashboards. While these lights can be a bit confusing, they both have specific purposes.

If you’re like me, the first time you saw the Jeep Wrangler Abs and Traction Control light on, you had no idea what they meant. What are these mysterious lights, and more importantly, what do they mean for your car? 

While this may be cause for concern, there’s no need to panic. In most cases, these lights coming on is simply a result of the Jeep’s computer system running a self-diagnostic test.

In this blog post, we’ll demystify these two warning lights and tell you what to do if they come on.

What do the Jeep ABS and traction control lights mean when they come on?

The Jeep ABS (Anti-lock Braking System) and traction control lights are important safety features that should not be ignored. 

If either light comes on, it indicates that there is a problem with the vehicle’s braking system or traction control system. Both systems are designed to help the driver maintain control of the vehicle in slippery or hazardous conditions. 

If either system is not working properly, it could put the driver and passengers at risk. If either light comes on, the best course of action is to bring the vehicle to a qualified repair shop as soon as possible for inspection and repairs.

Why Are My Jeep Wrangler's ABS and Traction Control Lights On

The ABS or traction control module is faulty

If you see the ABS and Traction Control lights on in your Jeep, it’s likely due to a faulty ABS or traction control module. 

The ABS module is responsible for keeping your vehicle stable while braking, and the traction control module helps to keep your tires from slipping on slick surfaces. 

Both of these modules are important for safety, so it’s crucial to get them repaired as soon as possible. 

Fortunately, there are many reputable shops that specialize in Jeep repairs, so you should be able to find a shop near you that can fix the problem quickly and affordably. 

Once the modules have been repaired, your Jeep will be back to its safe and reliable self in no time.

There are fuse issues

Your Jeep’s anti-lock brake system (ABS) or traction control light might be on because of a blown fuse. Contrary to popular belief, these two systems are not related. The ABS system uses sensors to monitor the speed of your wheels and modulate the brakes accordingly.

The traction control system, on the other hand, uses sensors to monitor wheel spin and applies the brakes to individual wheels as needed. Both systems rely on fuses to function properly, so if one of them is not working, it’s most likely due to a blown fuse.

Fortunately, replacing a fuse is a relatively simple task that can be easily completed at home with the help of a few tools. With a little time and effort, you should be able to get your Jeep’s ABS and traction control systems up and running again in no time.

Low tire pressure

Lack of proper tire pressure could be the reason why your Jeep’s ABS and traction control lights would be coming on. Your Jeep needs the right amount of tire pressure in order for the anti-lock braking system (ABS) to work properly.

If any one of your tires is low on air, it can cause your Jeep to lose traction and skid. That’s why it’s important to check your tire pressure regularly and inflate them to the recommended levels. If you’re not sure what those levels are, you can find them in your Jeep’s owner’s manual.

Inflating your tires to the proper levels will help improve your Jeep’s handling, braking, and fuel efficiency. Plus, it’ll help extend the life of your tires. So don’t ignore those warning lights on your dash—check your tire pressure as soon as possible.

Low fluid level

If you notice that your Jeep’s ABS and traction control lights are coming on, it could be due to a low fluid level. The braking system relies on fluid to function properly, so if there isn’t enough, the system may not be able to engage properly.

This can lead to longer stopping distances and decreased braking power. To avoid this, check the fluid level regularly and top off as needed. You should also have the brakes inspected by a professional if you notice any issues.

By keeping an eye on the fluid level and staying up-to-date on brake maintenance, you can help ensure that your Jeep’s braking system is always in top condition.

PCM failure

PCM failure

Any driver who has experienced the sudden onset of Abs and Traction Control Lights On knows the frustration and worry that comes with it. While these lights are typically just warning lights that indicate a potential issue with the vehicle, they can also be caused by a serious problem known as PCM failure.

PCM stands for the powertrain control module, and it is responsible for controlling the engine, transmission, and other vital systems. If the PCM fails, it can cause a wide range of problems, including Abs and Traction Control Lights On.

Sensor broken

If you’re driving a Jeep Wrangler, and you see the ABS and traction control lights come on, there’s a good chance it’s because of a problem with one of the sensors. The most common culprit is the wheel speed sensor, which is located at the front or rear of the vehicle. If this sensor fails, it can cause the ABS and traction control systems to malfunction.

In some cases, it may even cause the engine to stall. If you suspect that your Jeep has a sensor problem, the best thing to do is take it to a qualified mechanic for diagnosis and repair. With proper care and maintenance, your Jeep can continue to provide years of trouble-free driving.

Battery Problem

Traction control and ABS lights coming on in your Jeep could be caused by a voltage issue with the battery. If the voltage is low, it can cause both systems to engage. The first thing you should do is check the battery voltage with a multimeter. If it’s below 12 volts, you’ll need to charge the battery. If that doesn’t work, you may need to  replace the battery.

Wrong wheel alignment

The wheel alignment of your Jeep is important in making sure that your car operates smoothly. Unfortunately, bad wheel alignment is a common problem that can lead to a number of unpleasant consequences.

One of the most common issues associated with bad wheel alignment is the illumination of the ABS and traction control lights on your Jeep’s dashboard. This can be extremely distracting while you are driving, and it can also lead to decreased fuel efficiency.

In addition, bad wheel alignment can cause your Jeep to veer off course, making it difficult to keep it on the road. If you suspect that your Jeep’s wheel alignment is off, it is important to have it checked by a professional as soon as possible. Failure to do so could result in serious accidents.

Dirt and debris build-up

Traction control is an important safety feature on modern vehicles, helping to prevent wheels from slipping on slick roads. However, dirt and debris can build up on the sensors that are responsible for detecting wheel slip, causing the traction control system to malfunction.

In some cases, this may cause the ABS light to come on, as well. If you notice that your Jeep ABS and Traction Control lights are coming on more frequently, it’s important to have the sensors cleaned as soon as possible.

Otherwise, you may find yourself stranded on the side of the road with no way to get help. Thankfully, most auto shops offer sensor cleaning services at a reasonable price. By getting your sensors cleaned regularly, you can help to keep your Jeep running smoothly and prevent any potential accidents.


If you see the Jeep Wrangler Abs and traction control light on, don’t panic! In most cases, it’s just the result of the Jeep’s computer system running a self-diagnostic test. However, if the lights stay on after starting the vehicle, it’s a good idea to have it checked out by a qualified mechanic to be sure everything is working properly.
