Generally a 30 zone implies you are in town, where you are subject to children, pets, footballs, stopping traffic etc.
Cruise control is for long distances at a constant speed where you are not subject to rapidly changing risks - not for stop-go situations. In town you should be concentrating on what is going on and adjusting your speed constantly based on ...
The cruise control on a modern car is totally electronic – obviously it has to interact with the car's controls, but no more so than would happen in "manual" driving. There should be no reason why you can't turn it on or off at will.
Why is this that way? What is the purpose of being able to deactivate
it in 2 ways as well - using the master switch/button, and a separate
"cancel" one next to the set/restore buttons?
You're asking a control theory question that's easier to answer in pictures than in words. However, SE isn't great for diagramming so I'll try to ...
It appears to be a Rostra unit their site http://www.rostra.com/rostra-support.php has an extensive support page. That is why I asked about the tail lights, they mentioned it. I would go to the site input you vehicle info and click the support tab. They will give you step by step instructions included are calibration steps, which may be your issue.
This should be safe logically and based on personal experience. Most cruise control systems use engine vacuum to pull on the throttle cable and the vacuum is always there when the engine is on anyways, so there is nothing mechanical running behind your system switch.
2012 Mazda 3's have either electronic throttles or cable. The cruise control system with ...
As you say, the M52 engine does not have an electronic throttle. However, the M52 was available with cruise control, so retrofitting the BMW system will be the neatest solution (as a bonus, you'll get audio controls on the steering wheel!).
BMW actually produced a standard kit for dealers to retrofitting cruise control, which makes your life easier. This ...
Not normal for cruise control.
My Land Rover Discovery has "Hill Decent" mode which allows you to take your foot off the brake while going down steep hills. The computer then takes over controlling the speed of the vehicle using the brakes. This function is mainly for off-roading.
My Honda did this, I found it was the floor mat getting jammed against the gas pedal. Other than this it could be:
Worn out gas pedal cable, replace it.
Extremely dirty throttle body that is sticking, in this case clean the throttle body with approved throttle body spray cleaner.
Like you said, the P0571 is for the cruise control. There are several things which could set this code:
Faulty Brake Switch
Misadjusted brake switch
Brake Switch harness is open or shorted
Brake Switch circuit poor electrical connection
I'm going to take an educated guess that the vehicle is drive by wire (DBW), meaning that the you press the gas pedal, ...
There are two type of cruise control, passive (normal) and adaptive (has other names)
Passive cruise control targets a speed, it reduces throttle position to slow down, but if engine braking is less than the effect of a steep downhill, the car will gain speed. This type of cruise control is not integrated with the braking system.
Adaptive cruise control ...
Based on your replies to comments, here's the diagnosis:
Most likely, you tripped the overdrive. Most modern cars have this, and most people don't know about it.
Look at 2 things:
look at your shifter, there should be a second button under the shifter button. That's the button that activates and deactivates the overdrive.
Look at your dash, there should be ...
The VSS input pin is probably pulled high by the CCU. The ECM/PCM VSS output can probably only pull it low. If this is the case, you would expect to see what you are seeing. You could use a 10k resistor to pull the CCU input to 4.5V and then see if it starts to work as you expect, but I wouldn't recommend doing something like this unless you know what you ...
Adding a cruise control should not affect your warranty. Even if it did, it would possibly only affect the part of the warranty the part touches. What I mean by that is, for instance, if you installed an aftermarket steering wheel, it would probably void the warranty on the air bag system because the air bag system is associated with the stock steering wheel....
Your Peugeot cruise control is 'speed sensitive'. Sixth gear cruise control requires a road speed of 70-75 MPH. The gearbox computes the gear required to maintain a given road speed, if you select a gear to high for the speed you are doing cruise control is switched 'off', to prevent the engine from labouring.
Problem solved, here are two problems I had to fix
The ECU option is the one after the BSI one, it doesn't have ECU in its name, just a code.
If your cruise control stick does not have speed limit, do not activate it on BSI or in ECU.
Does anyone knows how to trick the limit to allow it to work in 3rd gear under 35mph?
I think your question may be misguided. The final effect you seem to be looking for is to be able to cruise at a specific speed while using the least amount of petrol, is that correct?
This is absolutely possible in modern internal combustion engine cars. You don't do it by turning the engine off and on again, or by depressing the clutch to let the car ...
The purpose of being able to deactivate your cruise control in two different ways (note: there are at least 3 including brake/clutch pedal switches/neutral safety switch) is that the cruise control system has two distinct 'deactivation states':
1) System off and disabled, like the off switch on your computer. No accidental press of the set/resume buttons ...
You have two options: aftermarket cruise, factory cruise
Most car alarm/stereo installation shops will be able to get and install aftermarket cruise control.
You can order them online such as here
General Motors Usually only has one wiring harness for the vehicle, meaning the vehicle with all the options has the same wiring ...
This sounds like a bad switch. Assuming the main cruise control system is responding but you aren't getting set, reset, coast, etc., then it's likely that one or more of the internal contacts has broken or come loose.
Annoyingly, those control stalks are integrated units. Easy to replace but not cheap.
There are actually choices for you out there. I'm not sure if these exact Universal Cruise Control units would work, but it should give you some ideas:
Rostra Universal Electronic Cruise Control 250-1223
Another possible option:
Audiovox CCS100 Universal Vacuum Cruise Control
A buddy of mine installed one on his car (older Nissan) and it worked perfectly ...
Your Nissan was built, tested and sold as an entity. Any changes to a vehicle would not be accepted by most, if not all, vehicle manufactures which they do not have any control or imput to and would void the warranty. Unless you know they are manufacturer approved fitments, you should check with the manufacturer, do not have them fitted. There have been ...
I would check the brake pedal cancel switch, it may be an integral part of the brake switch but has its own electrical contacts. If it is stuck in the open position this will cause cruise to not engage. You can check this with an ohm meter, pins 3 and 4 (first diagram) should have continuity with the brake pedal at rest, lose continuity when you depress the ...
I Think this is normal behaviour of a car which has upwards of 150/170hp.
When you are in your 3rd or 4th gear your speed should be more than 40kmph below that the car might stall.
The ECU is detecting the imminent stall and compensating by increasing the rpm and the speed of the vehicle , you do not need to press the accelerator for this to happen. ...
Cruise control is not generally considered to be a fuel economy feature. It's mainly intended for comfort and convenience on long highway trips, where fatigue can be a problem.
Traditionally, cruise control systems try to maintain a constant speed over time without driver intervention. They will accelerate to maintain that speed when going up a hill, for ...
I have VW Golf, which technologically should be similar to Audi, and I observe the same behavior you describe. I think the reason to keep the fuel on is that ECU can keep the speed constant in more cases, than with fuel shut off. Also with cruise control it seems to consume more fuel when you have many uphill/downhills compared if you use throttle manually.
If you don't have the wiring diagram that gives you the codes, then you can start by either:
1) identifying the fuses and what they supply can give an easy and quick idea of permanent supply, accessory supply and ignition controlled supply.
2) use a multimeter to find wires with the controlled supply needed. Make sure that the wires come from a supply ...
The P0567 code indicates that there has been a malfunction in the electrical components of the cruise control resume signal circuit, as detected by the PCM.
What the P0567 code means?
This is a generic power train diagnostic trouble code (DTC) and typically applies to OBD-II vehicles equipped with cruise control. That may include but is not limited to ...
When you reconnected it, did you just slip it on or did you push it on until it "clicked"? That's a snap connection.
If it's worn so much that it won't snap on any more, you could try running a little spring from that hook thing to the place where the cable sheath stops at that steel bracket (the one with both cables routed through it). The cable core ...
Did it stop working about the time you had the work done to your car (about 7 months ago I think you said)? Could be your mechanic didn't hook it back up, either physically or electronically. If so, take it back to that mechanic and have them take a look.
You can check the photo you posted in your other thread, there are two cables which are to the right of ...
