When does the cruise control warning light turn off?
Once a speed is selected, this light will turn green. If the computer has detected an issue, this light will stay orange and likely won’t turn off until the problem has been remedied.
Is there a problem with the cruise servo?
Absolute dead last on the list is the cruise servo itself on the driver’s side of the firewall. Beyond the possibility of a little oxidation on the connector, which is unlikely unless it’s been unplugged (it’s a weatherpak connector), these servos very rarely fail. And I mean very rarely.
How to troubleshoot a Chevy cruise control switch?
Using test light, (with clip attached to positive battery cable), test for voltage, (actually checking for a good ground), at black/white wire. Test Gray/Black wire with switch held on res/acc, voltage shoyld be present. There’s a whole bunch more but this ought to pretty much eliminate or condem the switch part.
What’s the problem with my Chevy Tahoe cruise control?
Shooting this over to the 88-98 Truck forum (due to this being the “old” body style Tahoe prior to the change in 99) for further assistance. Hey Chris, the most common problem is brake switch failure/out of adjustment. Do your brake lights work?
Once a speed is selected, this light will turn green. If the computer has detected an issue, this light will stay orange and likely won’t turn off until the problem has been remedied.
What to do if your Cruise Control is not working?
Check the fuse. You may need to look in the owner’s manual to see which one if it’s not tagged on the fuse box cover. An aftermarket cruise may have an inline fuse holder in the wiring to the controller. If there is power to the system, the next check is the brake lights. Brake lights?
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. If one of the brake lights has failed, the cruise control thinks the brakes are on all the time and won’t come on. Same result if the switch is incorrectly adjusted or broken or jammed.
What happens when your cruise control goes to 70?
The kids in the back seat have stopped threatening to throw up, too. Then you look in your mirror 20 miles later and see the lights. Red and blue flashing lights. You’re doing over 85 mph and, odds are, Smokey isn’t going to believe you have the cruise set to 70. Time to find out why your cruise control has a mind of its own.
What does the cruise control light mean on a car?
What the cruise control light means Most cruise control lights use 2 different colors to let you know what state the system is in. Typically, the cruise control light will be orange when the system is on, but a speed hasn’t been chosen yet. Once a speed is selected, this light will turn green.
What happens when your cruise control goes off?
If the wheels lose traction and the car starts to slow down, the cruise will speed up the engine to attempt to accelerate back to the set speed. This will make the drivewheels spin more briskly. The vehicle speed will go slower, regardless of how furiously the wheels spin.
How does a cruise control module detect speed?
The only way your cruise control module is going to know how fast the vehicle is moving is if the vehicle speed sensors feed this information to it. If the module cannot detect the speed because of faulty speed sensors, then the cruise control system will automatically deactivate.
Can a check engine light cause a cruise to not work?
If your Check Engine light is on, the cruise may not work, especially if the VSS is malfunctioning. Older vehicles may use speed information from the speedometer.
Why is the cruise control not working on my car?
Spiral Cable – Many vehicles mount the cruise control switch on the steering wheel. A faulty spiral cable may have an open circuit, preventing the switch from contacting the CCM. Control Switch – If the internal contacts wear out, the cruise control switch may not be able to contact the CCM.
Can a bad brake release switch cause a bad cruise control?
One of the symptoms commonly associated with a bad cruise control brake release switch is a cruise control system that cuts off unexpectedly. If the switch has any sort of contact or internal issues, it may cause the cruise control system to cut off unexpectedly when activated, even if the pedal is not stepped 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.
Why is my cruise control light not working?
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. Fuses and Relays – On some vehicles, fuses and relays are used to protect the cruise control actuator circuit.
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.

What can cruise control do for your car?
If your car has cruise control, it can reduce stress and help you stay alert on long drives. Benjamin Jerew is an ASE-certified Master Automobile Technician with over a decade of experience in auto repair, maintenance, and diagnosis.
What do you do if your Cruise Control is not working?
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. This electronically-controlled throttle body is modulated directly by the engine control module, both for direct driver input and cruise control.
Can a faulty brake switch cause cruise control to go off?
If a fault has been detected, most of the time only the cruise control will be affected. However, some of these faults can cause issues with other driving systems on the car. For example, a faulty brake switch won’t illuminate the brake lights when you step on the brake pedal.
How does a cruise control system work in a car?
Early systems used a vacuum motor and cable, but these eventually changed over to electric motors. Most recently, with the development of drive-by-wire or electronic throttle control systems (ETCS), cruise control is built into the engine control module (ECM), which controls the throttle body electronically.
