Cruise control not working again

• Add to quote

had this same problem a while back and that cause was the accessory fuse blown. well the fuse is good but i put a new one in anyway. brake light is not stuck on so its not the foot pedal switch. open up the switch compartment and the little piece that always seems to break that sits in the slot on the brake handle is not broken. dont see a crimped or broken wire , but how would that happen if it was never messed with. so i am stumped. when i turn on the switch on the dash it lights up red like it should, but when i engage the switch it doesnt turn green and obviously it doesnt work. the only code showing is for the cruise control fault so i am guessing its the switch ? with the fall riding season upon us and the leaves may turn color eventually :wink: i would like to have it working. if not for that, i would just wait till winter time to mess with it.  

Any changes in grips, bars, etc. ? Obviously something is shorting out the accessory circuit? Or the cruise control switch is damaged Sent from my iPhone using Tapatalk  

while sitting in the shed i also pulled clutch in light went to green. pulled brake in,light went to green. foot brake depressed, green light again. nothing was done to it. been using it since fuse replaced sometime ago. just stopped working  

Hmm seems to be working in opposite, I’d bet on an ecm fault Sent from my iPhone using Tapatalk  

Did you do something prior to the fuse blowing? Sent from my iPhone using Tapatalk  

nope but that was 2 years ago  

P0577 Code means there is an electrical fault in the cruise control circuit due to a failed switch, or abnormal voltage level in the input circuit.  

I had the same problem with my 2012 Custom. I found the front brake light switch was bad so I did a quick repair and all was well for a while. When the cruise stopped working again I used the Harley diagnostic check and found the set/resume switch was faulty. I replaced both the front brake lamp switch and the set/resume switch and all has been well ever since. I'll list below the Diagnostic Steps I used. Hope this helps. Mike U. 1. Hold cruise switch in the SET position. 2. Turn the cruise ON. 3. Turn the main power switch on, the cruise light should initially come on then turn GREEN, release the cruise switch the light will turn RED. 4. Push the cruise switch to RESUME the light should turn GREEN, release the switch, the light should turn RED. 5. Roll the throttle OFF make sure you roll it off to activate the cutoff switch for the cruise, the light should turn GREEN, release the throttle the light should turn RED. 6. Apply the front brake, the light should turn GREEN, release it, the light should turn RED. What you have done is test each of the SWITCHES that are in the cruise system. If, during any of the tests, the light does not turn GREEN, then that part is at fault.  

so again i went outside and did all the diagnostic with light going from red to green an d all does. took it apart again and made sure the plunger is still there and plunges. no signs of frayed wire. stopped at a guy that does harley customizing in the neighborhood and he said he would change out the switch assembly. so either i spend the 200.00 and try and change it and hope its the problem or take it to the stealer and fork out more money to be certain. i have not found a video on line for the change out. anybody have a link to one ?  

If you have external wiring, it's a breeze If you do. (Plug & Play) If you don't,good luck! The Plug is up in the fairing. Taking the fairing off is the longest part of the job.

5 Reasons Why Your Cruise Control Stopped Working

• Updated: March 15, 2023

It would be difficult to find a vehicle on the road today without cruise control. This invaluable feature makes driving long distances easier but can also cause trouble when it malfunctions. Understanding the reasons your cruise control stopped working ensures that you can get the problem fixed quickly for a more enjoyable ride. 

While this fault can cause issues with the cruise control system itself, there could also be an effect on the acceleration of your vehicle. That’s why you want to have it looked at as soon as you notice a problem. Let’s take a quick look at the reasons your cruise control may have stopped working.

Reasons Why Your Cruise Control Stopped Working

The most common reason a cruise control stops working is due to a blown fuse or a defective brake pedal switch . It can also be caused by issues with the throttle control system or the ABS. In older cruise control systems, it can be caused by a broken vacuum line.

Here is a more detailed list of the possible reasons your cruise control is not working:

1. Blown Fuse

All electrical systems in the vehicle are controlled by fuses. Your cruise control system is attached to a fuse that can blow if there is a short circuit or fault. Without a good fuse, the cruise control system can’t work at all.

Thankfully, it’s not difficult to find and replace a blown fuse. Look in the owner’s manual to find the fuse that corresponds with the cruise control technology. 

2. Defective Brake Pedal Switch

The brake pedal switch is responsible for turning the brake lights on and off based on the pedal position. Cruise control systems are designed to disengage whenever your brake pedal gets pressed. 

Because the cruise control is wired into the brake pedal switch, any fault can cause it to stop working. When the brake pedal switch malfunctions, the car believes the brakes are engaged, causing the system to turn off automatically. Not only that, but your car’s brake light might also be stuck on, leaving confused drivers in your wake. 

3. Malfunctioning Speed Sensor

Speed sensors are located on every wheel or differential. The purpose of these sensors is to monitor the speed of the wheels to determine if traction control is needed. 

The speed sensors are also part of the cruise control system. When a sensor fails, the cruise control can stop working and the speedometer might act strange as well. 

If there is an issue with a speed sensor, it will often show with an ABS warning light or a check engine light on the dashboard.

4. Electrical Issues

The cruise control system is electronic, with many components working together to make the system operate. If the cruise control fails to work, you want to check the wiring harness and associated connectors for a fault.

You also need to ensure that the voltage source is supplying enough power to the system. Even the smallest fault can cause defects with the cruise control. In many cases, there can be an issue with the cruise control lever or buttons causing the cruise control to not engage.

If your cruise control buttons are located on the steering wheel it could also be caused by a bad clock spring, which is located behind the steering wheel.

Check the system with an OBD2 scanner to look for any trouble codes related to the cruise control.

5. Damaged Vacuum Actuator, Hoses or Cable (Older cruise control)

If you drive an older vehicle with cruise control, you might have an issue with the vacuum actuator or the cable that connects to the throttle. If there has been damage done to the vacuum hoses or the actuator, the cruise control will stop working altogether.

Additionally, the cable linking the actuator to the throttle must be in good shape. If it has been broken, the cruise control will fail. 

What is Cruise Control?

Cruise control is a feature that is used when you are traveling at a consistent speed. Cruise control was first introduced for automobiles in the 1950s. However, it took many years before it became a staple in the modern vehicle.

This electrical system allows you to set a predetermined speed and take your foot off of the gas pedal. If you are on a long drive, there is less fatigue because you don’t have to try to maintain your speed. Cruise control can also benefit fuel economy because the vehicle uses less fuel when traveling steadily. 

In newer cars, you might be able to find adaptive cruise control , which is a smart technology. Adaptive cruise control allows you to travel at a predetermined speed, but it also helps to maintain a safe distance from the vehicles in front of you with the help of sensors. With conventional cruise control, you need to take over when the car in front of you slows down, but that’s not the case with adaptive cruise control. 

There are also vehicles nowadays with not only cruise control, but fully self-driving vehicles . We will most likely see much more of this in the future.

Cruise Control Repair Cost

The cost to repair your cruise control system depends on what caused it to fail. If you need to replace a cruise control or brake switch, you might spend between $125 and $350, including parts and labor. However, the cost to change a fuse is only a few dollars and you can perform the replacement yourself in just a matter of seconds. 

On the other hand, when something major fails, such as the actuator, you could be looking at a much higher repair bill. In some vehicles, the cost to replace a cruise control actuator can cost more than $700. These costs rise if you drive a luxury vehicle or one that is difficult to get parts for. 

It might not seem immediately important for you to fix the broken cruise control, but this defective system can affect other performance aspects. You could start to notice issues with acceleration or have trouble with the speedometer. To play it safe, it’s always best to have the cruise control repaired as soon as you notice a problem.

Is there a fuse for the cruise control?

Yes. If the cruise control is installed from the factory, you should check your car’s owner’s manual for the fuse location. If it’s an aftermarket cruise control, you’ll need to follow the wires to find the fuse.

Does the brake switch affect the cruise control system?

Yes. The brake switch affects the cruise control system. 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.

Will the cruise control work if the check engine light is on?

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. This is mainly due to safety reasons.

Can a vacuum leak affect cruise control?

Older vehicles use vacuum to control the throttle for the cruise control, and in this case a vacuum leak can heavily affect the cruise control. However, modern cruise controls are fully electric and in most cases will not be affected by a vacuum leak if the check engine light is not illuminated.

Although many people may think that the cruise control system is unimportant and not worth spending money to repair, the problem can be caused by a faulty part that will affect the engine’s performance or durability. Therefore, it is best not to ignore the problem if your cruise control is not working without first diagnosing the car properly.

If your cruise control still isn’t working after trying all the tips in this article, it’s probably time to take it in for a professional opinion from a mechanic. It may be a more serious problem that requires replacement parts or repairs. In the meantime, drive safe and enjoy the open road!

How Does Cruise Control Work?

Cruise control systems work by utilizing a combination of components to maintain a set speed in your vehicle. Understanding how cruise control systems function is crucial for diagnosing and troubleshooting any potential issues.

When you activate the cruise control system by pressing the ‘on’ button, it enters into a standby mode, awaiting your instructions to set the desired cruising speed. Once you have reached the desired speed, you can set it by using the control buttons typically located on the steering wheel or stalk.

Now, let’s delve into the inner workings of a cruise control system. Once the cruising speed is set, the cruise control module takes control of the throttle body , which regulates the amount of air entering the engine. By adjusting the throttle body opening, the system maintains the desired speed, compensating for changes in incline and external factors.

During operation, various sensors constantly monitor the vehicle’s speed, throttle position, and other relevant parameters. These sensors provide continuous inputs to the cruise control module, which in turn adjusts the throttle body opening accordingly to maintain the desired speed.

If you need to cancel the cruise control function, you can do so by pressing the ‘cancel’ or ‘off’ button or applying the brakes. These actions deactivate the cruise control module, allowing you to regain control of the throttle and return to normal driving mode.

It’s important to note that cruise control systems are not fully autonomous. They assist the driver in maintaining a constant speed but still require attentive driving and awareness of the road conditions.

2015 Road King Cruise Control

• Add to quote

2015 road king the cruise control stopped working. The amber light won’t come on or set a speed any help would be appreciated. Modifications: FP3 programmer, Arlen ness 65 degree air breather, screaming eagle street cannons, saddle bag light projectors (Amazon) with the Harley one logo(I soldered them into the turn signal or the break light wiring I can’t remember). I will remove the bag lights on my next day off. When I press the rear break light and it comes on and goes off! The front break lever does the same.  

You probably caused the problem with the projector lights. The cruise won't set with the brake light on. Sent from the secret underground bunker  

Like norm9278 said, cruise won't set with the brake light on. Check your fuses as well, beneath the side panel, to be certain a fuse did not get in the incorrect slot. Been there, done that! Actually, the Harley tech did that for me. I had to fix his error.

Cruise control on '01 Road King standard

• Add to quote

I asked my dealer yesterday about adding a cruise control system on my '01 RK FLHRI and was informed that H-D's unit has been discontinued. What now? Does someone else out there in the aftermarket offer a nice set-up for my scoot?  

H-D has discontinued the '99-01 cruise control.  

I was told the 02 and later one will work with an aftermarkey wireing harness. I will see if I can find the site. Also there was a guy here selling a unit. http://groups.msn.com/HarleyTechTal...ssage=278410&LastModified=4675440937874521249  

How well do the '99-02 cruise control units work? I heard Harley discontinued them because of numerous problems. Anyone heard this before?  

The web site where you can get wire harnesses is http://www.vintageparts.org/ The part number is in question. I found a bunch in the range of 70141-98 and on. I would call them.  

As far as problems? I know many different people with ultras that have had no problems with the cruise. Bikes from 98 right up through 03 and no one that I ride with has complained about the cruise. The kit contains the same module that is put into Ultras.
