Have you ever noticed that the ABS and traction lights come on when driving your Jeep Patriot? While this is a bit alarming, it’s a safety feature that helps to keep your vehicle on track and under control. But unfortunately, the sudden onset of these lights in the instrument cluster often indicates that the traction control component or the ABS unit of the vehicle has malfunctioned.
ABS and traction control lights can be ON in Jeep Patriot primarily due to a fault in the ABS module, damaged wheel speed sensors, low fluid level, and blown-out fuse. Fortunately, most of these issues can be easily resolved with the proper diagnosis and approach.
In this article, I will elaborate on why the traction control and ABS lights turn on in the Jeep Patriot and how they could be fixed.
Reasons for the Onset of ABS and Traction Control Lights:
There are quite a few simple and primary reasons why the traction and ABS lights might come on. Those are discussed below:
1. A Fault in the ABS Module:
One of the the most common causes of the ABS and traction control lights being on is a fault in the ABS module. For example, a bad wheel speed sensor, an ABS control module, or a wiring issue can cause this. If the diagnostic test indicates that the ABS unit is faulty, it will need to be replaced or repaired.
In some cases, the traction control light may turn on even when the ABS is working correctly. This is usually due to a faulty traction control module or a wiring issue. The traction control system will need to be tested and repaired in these instances.
A faulty ground connection to the ABS module also causes ABS module failure. This can occur when the ABS module connector pins 16 and 47 are not receiving a proper ground signal from the chassis.
Without this ground signal, the module will not be able to properly control the ABS and traction control systems, causing the lights to come on.
Below are the part numbers having the highest number of ABS module failures:
- 25.0212-0919.4 / P68028215AD
- 25.0212-2177.4 / P68212478AA
- 25.0212-1845.4 / P68091115AD
- 25.0212-0534.4 / P05105961AB
- 25.0212-1845.4 / P68091115AD
How to Fix:
It is best to use an OBD2 scanner to diagnose the issue accurately. This device will provide specific information about the issue, such as which parts are causing the problem.
The ground connection can be relatively easy to fix. The first step is to verify that pins 16 and 47 of the ABS module connector have an excellent connection to the ground. These pins are tied to the chassis ground G110, found on the chassis near the washer fluid tank.
If the connection between the pins and the chassis ground is poor, the best thing to do is to cut the ring lug off and add a new one to each wire.
After doing this, checking if the ABS and traction control lights are still on is essential. There may be a more severe issue with the ABS module itself if they are.
In this case, it’s best to take the vehicle to a mechanic for further diagnostics and repairs.

2. Damaged Wheel Speed Sensors:
The most common cause of the ABS and Traction Control Light coming on in a Jeep Patriot is broken wheel speed sensors.
Wheel speed sensors measure the rotational speed of the wheels and relay that information to the vehicle’s computer (microcontroller). This allows the module to shift power to the appropriate wheel when needed.
When a wheel speed sensor becomes dirty or damaged, it can no longer accurately convey information. This means the ABS and TCS modules cannot know when to adjust, resulting in the ABS and Traction Control Light coming on.
How to Fix:
STEP 1: You must first locate the wheel speed sensor with the help of an OBD 2 scanner and clean or replace it. If the sensor is damaged, it must be replaced. Replacing a wheel speed sensor is relatively easy, but ensuring you get the correct part is essential.
STEP 2: Once the wheel speed sensor is replaced, you will need to reset the traction control module. This can be done by disconnecting the battery, then reconnecting it.
STEP 3: The ABS and Traction Control Light should then go off.
If the light is still on, a more severe problem may need to be addressed. You may need to take your Jeep Patriot to a certified mechanic to have it properly inspected and diagnosed.

4. Low Fluid Levels of Brake:
When the ABS and Traction Control Light are ON in your Jeep Patriot, it could result from low fluid levels in the brake system. This happens when the pressure sensors in the brake lines detect insufficient fluid to ensure proper brake function.
The brake system of the Jeep is hydraulic, meaning it relies on the pressure of a cylinder pressing against a fluid to close the brake pads and bring the vehicle to a halt. For this to work, the fluid level needs to remain consistent.
If the fluid level is too low, it can cause the brakes to become spongy and difficult to control. The Jeep’s computer can detect this via sensors, which will trigger the ABS light if it does.
Several factors, including a gradual leak or the fluid evaporating, can cause low fluid levels in the brake system. Therefore, it is essential that the fluid levels are checked regularly and topped off if necessary.
How to Fix:
If the fluid levels in your Jeep’s brake system are low, it is essential to take it to a qualified mechanic as soon as possible. They will be able to diagnose the problem and top off the fluid levels.
Doing this will help ensure that your Jeep Patriot remains able to stop safely, and the ABS and Traction Control lights will be turned off.

5. Blown Out Fuse:
A blown-out fuse of the traction control system or the ABS component of the vehicle might lead to the sudden onset of the warning lights in the instrument cluster.
As a result, you should first check fuses 34 and 35 to ensure they are correctly seated and not loose.

How to Fix:
If the fuse is found to be blown out, you should immediately replace it. Usually, this simple step will make the warning lights go away.
6. Malfunctioned Computer/ECU:
Sometimes, the reason for this warning light to come on is due to a malfunctioned computer or ECU. The ECU, or Electronic Control Unit, is a computer system responsible for controlling the vehicle's various systems, such as the engine, transmission, suspension, and brakes.
If the wiring of the ECU is disrupted in such a way that a specific component is not receiving the necessary signals, it can cause the ABS and Traction Control Light to come on.
How to Fix:
To properly diagnose and fix the issue, it is best to seek the help of a specialist trained in electronics.
A typical mechanic likely won’t be able to diagnose and fix the issue adequately, so it is best to seek the help of an authorized Jeep dealership. They can diagnose the problem, perform the necessary repairs, and reset the warning light.
7. Bad Wheel Alignment:
If you’re driving a Jeep Patriot and the ABS and Traction Control Light has suddenly come on, it could be due to a bad wheel alignment.
Over time, wheel alignment often wears out, causing misalignment in your Jeep. This can cause the traction control and ABS lights to start up, alerting you to the problem.
How to Fix:
The wheel alignment can easily be reset, and the warning lights should turn off if done correctly. However, getting it fixed sooner rather than later is essential, as a misaligned wheel can cause many other problems.
9. Low Battery Voltage:
When the voltage of the vehicle’s battery gets weakened, numerous warning lights appear in the instrument cluster without any appropriate reason.
How to Fix:
You can replace the battery in the engine bay to resolve the low battery voltage.
10. Turned OFF Traction:
Sometimes the ABS and TCL lights are on if you accidentally/intentionally turned the switches off. When you turn the switch off, the warning light will remind you that the critical safety feature is not working.
In this case, no further action needs to be taken, as the system has been intentionally turned off.
How to Fix:
You can toggle the ABS, and TCS features ON to get rid of the warning lights.
11. Low Tire Pressure:
When the air pressure in the tires of the vehicle comes to a level lower than usual, the traction and ABS lights often show up in the instrument cluster to indicate that the air pressure should be checked.
The lights will remain illuminated until the air pressure is back up to the proper level, usually around 30 to 35 PSI, depending on the vehicle.
How to Fix:
Checking the tire’s leakage is recommended to avoid low tire pressure. If there is leakage or any issue, it is recommended to treat it or change all tires.
