CRUISE CONTROL SHUTS ITSELF OFF

2001 Honda Civic

Electrical problem

Hello-

I've recently begun to experience issues with my 2001 Civic LX cruise control. The issue is that the cruise turns itself off, most notably when hitting slight bumps on the highway. After it shuts itself off, I can sometimes turn it back on after waiting a bit (~1 min), and other times it won't turn back on until after stopping and restarting the car. Occasionally it shuts down even without any noticeable bumps in the road.

It seems that perhaps something is loose somewhere? Any direction you can provide would be much appreciated.

Hi jeuvideo,

Thank you for the donation.

Yes, you are correct about something being loose and the most probable cause would be the brake and/or clutch switch.

Check the clearance between the switches and pedal stopper. Excessive clearance would cause the switch to activate if there is any vibrations.

Thanks for the quick reply!

Your response leads to me to a couple of questions, which relate to my lack of familiarity with the parts of my car.

1. I obviously know where my brake and clutch pedals are. Where do I look to find the associated switches and stoppers? How can I recognize these?

2. How much clearance is too much?

3. What can I do about the clearance, if it is in fact excessive?

Thanks.

If you look up the pedals from under the dash,you would see the switches on a bracket. On the pedal there would be a small brcket that holds a rubber stopper.

If the stopper is bad, you would only see a bracket with a small hole. The switch pin is supposed to pushed by the stopper.

When the pedals are released, the stopper should have minimal clearance between the switch.

CLUTCH PEDAL, CLUTCH PEDAL POSITION SWITCH, AND CLUTCH INTERLOCK SWITCH ADJUSTMENT
NOTE:

• Remove the driver's side floor mat before adjusting the clutch pedal.
• The clutch is self-adjusting to compensate for wear.

If there is no clearance between the master cylinder piston and pushrod, the release bearing will be held against the diaphragm spring, which can result in clutch slippage or other clutch problems.

1 . Loosen locknut (A), and back off the clutch pedal position switch (B) (or adjusting bolt)
until it no longer touches the clutch pedal (C).

2 . Loosen locknut (D), and turn the pushrod (E) in or out to get the specified height (F) and stroke (G) at the clutch pedal.

3 . Clutch Pedal Stroke: 130 - 140 mm (5.1 - 5.5 in.)
Clutch Pedal Height: 198 mm (7.8 in.)
Tighten locknut (D).

4 . With the clutch pedal released, turn in the clutch pedal position switch (B) until it contacts the clutch pedal (C).

5 . Turn in the clutch pedal position switch (B) an additional 3/4 to 1 turn.

6 . Tighten locknut (A).

7 . Loosen locknut (H) and the clutch interlock switch (I).

8 . Press the clutch pedal to the floor.

9 . Release the clutch pedal 15 -20 mm (0.59 - 0.79 in.) from the fully pressed position, and hold
it there. Adjust the position of the clutch interlock switch (I) so the engine will start with the
clutch pedal in this position.

10 . Tighten locknut (H).

I have a 2001 Honda Civic LX as well, only it has 133,000 miles and it is an automatic. Recently I too have begun to experience a similar problem, where my cruise control will engage just fine, but it will shut off after various amounts of time driving. When it does this, I need to turn off the cruise control (using the button by the drivers door at knee level) and turn it back on if I want the cruise to engage again, but it will not stay on long after that.

Any suggestions? Did the looking into the brake/clutch switch solve your problem? Thanks.

For your model there would be no clutch switch. You have the brake switch and gear position switch.

Not all causes are the same so you should start with the basics and that is to check the switches which are simple to do.

I also have a 2001 Civic LX, but mine has 210,000 miles. I have had a bunch of small problems with the car. Just today I replaced the heat sensor that activates the cooling fans. This was a simple solution to a serious problem that you will probally face somewhere down the road. I wasn't sure what was wrong at first, but I was stuck in horrible traffic on the GWB in New York. So I turned the heat on full blast which managed to get me back home without destroying the engine(I had to turn the engine off a few times).

When you are faced with this, it might be an emergency situation. Make a mental note, don't put the heater on, try putting the air conditioner on high. The A/C compressor will engage the cooling fan bypassing the heat sensor.

To get back on the subject, here I am driving home with the heat on full blast and the vents almost melting... I could barely focus on my speed with all the heat, so I tried the cruise control. What do you know, it shuts off after 5 to 10 minutes and refuses to turn on again. With the heat and blower on full blast, windows open and two bikes on the roof racks, I didn't get too far without having to pull off to the service area and refuel. Once I got back on the road I tried my cruise control and sure enough it was working again. But what do you know... It shuts off again in around the same amount of time.

I will continue to keep an eye on the functionallity of my cruise control, but it might have something to do with overheating. I've been noticing that my key has been overheating as well.

Here's another issue I ran into, the blower stopped working some time before. All that needed to be replaced was the resistor switch thing. Cheap fix you can diagnose yourself using a paperclip to bypass the resistor switch. The part is usually stocked at Honda dealers for about $80.

Another issue I had involved a moaning sound from under the hood coming from the compressor/alternator area. Turns out the bearing went bad on the clutch for the A/C compressor. This is another simple fix, but it involves removing your alternator. At this time buy a new alternator and same yourself the work of replacing it later. You may not have this problem if the plastic shields under your car are in good condition. Mine had fallen off over the years. If yours are missing, put new ones on. I paid alot for my new plastic, about the same amount for the alternator and clutch.

There is another problem that can occur if you don't have plastic shields under the car. It starts with a wierd sound from the engine. After you turn off the radio you should here the sound a little clearer. It will sound sort of like a meow. After popping the hood you should find something similar to the photo below.

Keep the plaster shields on and those furry pests out.
