What to do if your Cruise Control is not working?

If the mechanic determines that there is a bad fuse, he or she will find the corresponding fuse for the cruise control system to see if it has failed. If the fuse has blown, the mechanic will remove it and replace it with a fuse rated for the correct amperage.

What happens when the fuse on the cruise control blows?

A mechanic will let you know what kind of setup you have on your vehicle. Bad Fuse: Like many electronically controlled systems in your car, the cruise control has a corresponding fuse which will blow to protect the system if it senses a short circuit. When the fuse of for the cruise control blows, the cruise control will stop working altogether.

Why does my cruise control turn off when I Touch the brake?

Brake lights? Yup, cruise controls have a switch to toggle them off when you touch the brake pedal, and many use the same switch as the brake lights.

What to do if your Cruise Control is broken?

Using a fuse puller, pull the fuse off the panel. Examine the cruise control fuse or use a fuse tester to determine if the thin metal strip inside the fuse is broken. If so, install a fresh fuse of the same amperage. A cruise control mechanism has a vacuum-powered actuator connected to the control module by vacuum lines.

Why is my cruise control not working properly?

The speed sensor is like a small plug protruding off the transmission with various wires attached to it. Visually check the wires for any signs of damage. A faulty or damaged wire on your speed sensor means that the speed sensor cannot relay your vehicle’s speed. A power surge can easily blow out the fuse of your cruise control mechanism.

Why does cruise control not work when brake light is blown?

Brake Lights – In some systems, cruise control is disabled when a brake light is blown. Aftermarket lighting, such as LED brake light conversion, might trick the CCM into thinking a brake light is blown, as LED bulbs draw less current than incandescent bulbs.

Where is the fuse on the cruise control?

Figure 1. A good fuse (on the left) compared to blown fuses (on the right). This switch is located on the brake pedal assembly and allows current to flow to the cruise control module to signal cruise deactivation.

Can a brake light disengage cruise control?

Brake Light Switch – As cruise control is automatically cancelled by depressing the brake, some vehicles may disengage cruise control if it cannot detect the brake light switch. Brake Lights – In some systems, cruise control is disabled when a brake light is blown.

How does a cruise control system work on a truck?

Some older systems, used on cars or trucks that don’t have throttle-position sensors, may have a rod that moves in and out of a magnetic coil to tell the controller the throttle position. There are also two electrically operated solenoid valves. One valve admits vacuum to the diaphragm chamber to add more throttle.

Why is my cruise control not turning on?

Common reasons for this to happen: Because cruise control systems have been designed to disengage when the brake pedal is pressed, the cruise control is wired to the brake pedal switch. If the brake pedal switch fails, the car may think the brakes are engaged and not allow the cruise control system to turn on.

How does an adaptive cruise control system work?

Adaptive cruise control systems, sometimes called “smart” cruise, use radar or laser detection to maintain safe distances from vehicles ahead. Some adaptive cruise control systems merely reduce engine speed to maintain distance, but some of the newest adaptive cruise control systems can also engage the brakes to slow or stop the vehicle.

It supplies the cruise control system with the vacuum necessary for it to operate, and without it, the system cannot function. For this reason, if you suspect that your vehicle may be having an issue, have the vehicle inspected by a professional technician, such as one from YourMechanic.
