Through this blog, I hope to share my knowledge and insights with fellow diesel enthusiasts and provide a platform for discussion and learning. Remember, these are just a few potential causes for your cruise control system’s inability to resume speed. If the issue persists after troubleshooting, it is recommended to consult a professional mechanic who can provide further assistance and ensure a thorough diagnosis. The switch circuit or fuse may just need to be replaced for the problem to resolve. Depending on which buttons are faulty, your whole cruise control can stop working or just some functions won’t work. The spiral cable connects all the switches from the steering wheel (in case your steering wheel has switches) to their respective modules.
Defective Brake Pedal Switch
Not only that, but your car’s brake light might also be stuck on, leaving confused drivers in your wake. There are several different types of cruise control systems, but all implementations share similar basic components. There is a sensor to measure vehicle speed, a throttle position sensor, and some mechanism to control the throttle plate without the use of the gas pedal. This can result in inconsistent or unpredictable acceleration patterns.
2. Throttle Adjustment:
In most cases, you’ll need to replace the switch if it’s not working correctly. However, if you’re lucky, you might be able to clean it and get it working again. So if you hit the button or switch but you don’t see a light illuminate anywhere, it could be an indication that the button or switch itself is bad. Check each of these areas and see if they’re the cause of your cruise control issue.
Does cruise control malfunction trigger the check engine light?
This is the cable that runs from the cruise control module to the throttle body. One of the most common reasons that cruise control might not be working is because of a faulty vehicle speed sensor. This is the sensor that tells the cruise control system how fast you’re going. If issues persist, investigate the brake switch for potential malfunctions or consider replacing it.
So, if you ever find yourself in a similar situation, give this quick fix a try to keep your vehicle running smoothly. The steering wheel of your Jeep Wrangler features an “On” and “Set” buttons specifically for cruise control. This enhances driving comfort and offers practical benefits during long journeys. First, let me give you an overview of how cruise control operates in Jeep Wranglers and why it’s a game-changer for those extended road trips. Hi, I'm Chris Brunson, and I'm passionate about diesel fuel and all things related to it. With over 5 years of experience in the industry, I've gained a deep understanding of diesel fuel properties, engine performance, and fuel efficiency.
This article is for informational purposes ONLY and is NOT a replacement for professional advice! ALWAYS consult your local specialist for an appropriate solution to your problem. Even though it doesn’t explain how to fix your cruise control, it gives you an idea of where to start looking if you are going to do it yourself. Check the system with an OBD2 scanner to look for any trouble codes related to the cruise control.
Let’s take a quick look at the reasons your cruise control may have stopped working. All of these reasons can make your cruise control ineffective and the worst thing is if it malfunctions while you are using it. It’s also a bad thing since cruise control saves gas while on long journeys down the highway, so you’ll want to fix the problem based on the listed reasons as soon as possible. If it’s not working correctly, then the cruise control system won’t be able to maintain the correct speed. If the cruise control system is engaged but the car doesn’t seem to be responding, it could be because of engine or transmission problems.
Malfunctioning Speed Sensor
Turn off the ignition, patiently wait for at least 30 seconds, reconnect the battery, and allow your vehicle to undergo a full reboot. This process acts as a gentle wake-up call for the cruise control, resolving the temporary disturbance. While cruise control can make long drives more comfortable, remaining attentive and engaged is crucial.
The cruise control system in your car is made up of a few different parts. There’s a cruise control switch, which is usually located on the steering wheel, that turns the system on and off. To fully understand why cruise control stops working on a car, we researched the most common reasons so that you know exactly what’s wrong with it. Adaptive cruise control gives an extra layer of convenience while driving, as it adjusts your vehicle’s speed based on the distance to the car in front of you. Older vehicles that are equipped with cruise control have two throttle cables – one for the gas pedal and one for the cruise control system.
A vehicle’s cruise control needs to be able to determine the vehicle’s actual speed. This enables the system to determine how much throttle needs to be applied in order to keep a certain speed, among other things. The brake switch sends a signal to the cruise control system to let it know when the brakes are being applied for the engine to know when it should stop accelerating. You also need to ensure that the voltage source is supplying enough power to the system. In many cases, there can be an issue with the cruise control lever or buttons causing the cruise control to not engage. On the other hand, if you apply less pressure, the valve is nearly closed, slightly letting air in.
The speedometer speed sensor is not always the sensor used by cruise control. Some systems rely on the ABS speed sensors, others do an average and some have a dedicated speed sensor. The cruise control function will be disabled when the check engine light is on in most car models, even if the cause of the check engine light is not the cruise control itself.

By modulating engine speed, the CCM can maintain your desired cruising speed on the highway. You can increase or decrease cruise speed by tapping a button or lever, and you can cancel cruise control by hitting the “Cancel” or “Off” buttons or stepping on the brake. Before electronic injection and electronic throttle bodies, some cars had the cruise control function. If there is a problem with your vehicle’s throttle body, your cruise control won’t work.
