ABS Light ON? Here’s How to Turn It OFF on Jeep Wrangler

Jeep Wranglers are highly sought-after vehicles renowned for their robustness, reliability, and off-road capability. As part of their standard safety features, Jeep Wranglers come equipped with an Anti-lock Braking System (ABS) that is designed to help with stopping power and preventing skidding. However, when the ABS light illuminates the dashboard, it can be a sign of trouble, and it is essential to resolve the issue quickly.

To turn off the ABS light on a Jeep Wrangler, use an OBD-II scanner to diagnose the underlying issue. A faulty wheel speed sensor is often the cause. If the OBD-II scanner can’t diagnose the root cause, you can try resetting the ABS light by disconnecting the battery.

In this article, I will discuss how you can get your Jeep Wrangler’s ABS light turned off in no time. So, stay along!

Functioning of ABS System in Jeep Wrangler:

The ABS in a Jeep Wrangler helps to prevent the wheels on the vehicle from locking up during heavy braking. This can help the driver maintain vehicle control and avoid skidding or sliding on the road.

Here’s how it works:

  • Sensors are located at each wheel to monitor wheel speed.
  • When the ABS is activated, it rapidly pumps the brakes to prevent the wheels from locking up.
  • The ABS can be activated when the driver applies heavy pressure to the brakes or when the system detects that the wheels are about to lock up.
  • The ABS allows the driver to continue steering the vehicle while braking, which can be especially useful in emergencies.
  • The ABS can be identified by a warning light on the dashboard and by a pulsing sensation in the brake pedal during heavy braking.

What Happens If the Jeep Wrangler ABS Light Is Turned ON?

If the ABS light on your Jeep Wrangler turns on, it means there's a problem with your Jeep's ABS. The light may be yellow, amber, or orange. It gets turned on for a short period (a few milliseconds) every time you start your car as part of a system check, and if it stays on while you're driving, it means something is wrong.

The ABS light will stay on when a problem is detected in the ABS system. The leading cause of this is usually a faulty wheel-speed sensor or ABS control module.

The wheel-speed sensor monitors the speed of the wheels, and the ABS control module manages the system.

If you’re experiencing an ABS light issue, the best thing to do is to take your Jeep Wrangler to a mechanic as soon as possible. The mechanic will inspect the ABS and diagnose the problem.

Typical Reasons Why ABS Light is On in Jeep Wrangler:

Following are the three typical triggers that will turn on the light:

1. Faulty ABS Module:

One of the reasons for an ABS light to come on in a Jeep Wrangler is a faulty ABS module. The Jeep ABS control module is a computer-controlled (microcontroller) program that receives data from the ABS sensors and uses it to control the braking system.

The module acts as the brain of the ABS, and it is integrated into the brake lines to help regulate the pressure applied when you press the brake pedal.

In some cases, the ABS module could fail, which would cause the ABS light to come on. Typically, if this is the case, you will need to have the module replaced.

2. Low Level of ABS Fluid:

One common reason the ABS light turns on is when the ABS fluid level is too low. The ABS fluid level must be consistently at the right level as the brake system uses a hydraulic medium to press the brake pads and bring the wheels to a stop.

If the fluid level falls below the recommended level, likely, the ABS will not function as it should, and the ABS light will be illuminated.

There are several causes of low fluid levels, including leakage or slow evaporation. If you suspect that the ABS fluid level is low, it is essential to check it as soon as possible.

You can access the fluid level by checking the reservoir under the hood. If the fluid level is low, you will need to top it off with the correct type of fluid recommended for your specific model of Jeep Wrangler.

3. Wheel Speed Sensor Malfunction:

One of the most common causes of an ABS light on in a Jeep Wrangler is damaged wheel speed sensors. The Wrangler has ABS sensors on each wheel hub that measure the speed of each wheel and send the information to the ABS control unit. The ABS light will turn on if a sensor malfunction and sends inaccurate or no speed information.

The wheel speed sensors on a Jeep Wrangler are exposed to harsh conditions due to their proximity to the wheels. This makes them more prone to damage and a potential cause of the ABS warning light.

Diagnosing the Faulty Wheel Speed Sensors:

It is not usually possible to identify a faulty ABS sensor in a Wrangler by physical inspection. However, with the help of an OBDII scanner in your vehicle and reading the error codes, you can diagnose the exact faulty ABS speed sensor. This will make it easier to determine which sensor is affected.

Once the faulty sensor has been identified, it must be replaced to resolve the issue with the ABS. Make sure the code reader you are using is compatible with your vehicle’s ABS to get an accurate diagnosis.

In summary, damaged wheel speed sensors are one of the leading causes of ABS warning lights in Jeep Wranglers.

If you experience this issue, get your vehicle checked out by a qualified mechanic to diagnose and resolve the problem correctly.

4. ABS Module is Turned OFF:

One of the most common reasons for a Jeep Wrangler ABS light to be on is that the ABS has been deactivated/turned OFF.

When the ABS is deactivated, the ABS light will show you that the feature is not active. This can be done unintentionally if you accidentally press the ESP_OFF (PATA) switch.

In such a scenario, there is nothing wrong with the ABS sensors or module, and you need to turn off your ESP_OFF switch after locating it (by consulting the owner’s manual).

5. Blown Fuse:

A blown fuse can cause the ABS to cease functioning. The fuse is responsible for supplying power to the ABS, and if it’s blown, the system won’t be able to operate. 

  • STEP 1: The first step is to find out if you have a blown fuse. You need to check the fuse box cover or the owner’s manual of your Wrangler to find the exact location of the fuse for the ABS. 
  • STEP 2: If the fuse is blown, you need to replace it.
  • STEP 3: Once you’ve replaced the fuse, turn your Jeep Wrangler on and check to see if the ABS light is still on. 
  • STEP 4: If it is, you’ll likely need to look at other possible reasons why the ABS isn’t working.

How to Turn OFF the ABS Light on Jeep Wrangler:

If your Jeep Wrangler has an ABS (Anti-Lock Braking System) light on, it’s essential to turn it off. Below I compiled a step-wise guide that helps diagnose the issue and turn off the ABS light.

  • Step 1: Find the OBD2 scanner connector on the left side of the instrument panel. Once you have located it, plug it into the diagnostic port.
  • Step 2: Using the OBD2 scanner, read any codes that may come up. For example, you may see a code such as ‘C102A’. This code will tell you what parts may be causing your ABS light to stay on. C102A indicates an issue with the Left Rear Wheel Sensor.
  • Step 3: Take the Jeep out for a drive, and check to see if any parts are stuck at 0 or not showing any readings. If this is the case, you may need to take it to a professional mechanic to get it fixed.
  • Step 4: After the issue is fixed, you should be able to turn off the ABS light. To do this, turn the key to the “on” position and press the “check engine” button. This should reset the system and turn off the ABS light.

These steps should help you diagnose the issue and turn off the ABS light on your Jeep Wrangler. Contact a professional mechanic for assistance if you cannot get the ABS light turned off.
