Cruise control buttons are being weird.

[SharpyClio]

Okay, so my French car is doing French car things.

now the engine runs sweetly the cruise control buttons have decided to move themselves about.

in essence the - button now sets the speed and adds mph, the + button cancels, the R button removes mph and the o button resumes.

any ideas? I have the error code df235 which is a cruise control error, I think it could be the actual buttons or the squib but has anyone come across this before?

Try fixing df235 first.

Is that the cruise limiter fault due to brake pedal sensor circuit?

 

[SharpyClio]

It’s not the brake sensor one, had a search and that shows as a df135. I’ve also adjusted the brake sensor as per the guide and it’s made no difference.

 

[SharpyClio]

It’s also the only code I get. No others stored at all (which is some sort of miracle lol)

 

[JamesBryan]

Sounds like the buttons/squib then 😏

Have you had the wheel off or anything?

Or has it just suddenly happened?

 

[SharpyClio]

I swapped the wheel as it didn’t come with the proper sport wheel. It’s worked okay, the odd blip where it wouldn’t set but nothing like this. I have some spare buttons so will start there I guess.

Worth a look.

Can't say I've ever seen this fault before 😅

So happy my cars unique. Ffs 🤣

Mines sometimes special but I think the buttons are just a bit w**k or the connection is a bit naff

If you press them mega hard they work. Or sometimes you go to cancel the cruise but the car just goes "lets start accelerating towards the car in front" 😂 Its all based on resistance too so each resistance gives a different signal

 

[SharpyClio]

Interesting. I shall try poking them harder if swapping them doesn’t help.

I had that on mine. unfortunately sold it before I ever managed to work out what was going on, so absolutely no use to you unfortunately.

I like the way that you could never work out which button was going to do what as the functions moved around. Fairly sharpens the mind!

I'm not sure if this helps but I had the same issue.

I don't run the standard steering wheel, but aftermarket one with a separate C/C bracket and buttons.

It was annoying me so I disconnected it all and ran it for a month without it fitted. I wanted it back for a big journey so I refitted and it's been fine since.

It might be worth a try as it's free!

Interesting, thats a good and as you say, cheap, idea! I'll give it a go,.

Fixed them! I swapped out the switches for some i had on another wheel and they are all fixed and working as they should. Cheap fix in the end. So the moral is that if you get the above code alone start with the switches.

I have this problem, live data shows after braking the switch is still closed and thinks the brake peddle is still being pressed. If I lift the peddle with my foot the circuit opens and the cruise starts to work again. I need to adjust it or get a new switch as if going over a big bump is enough to trigger the switch and will cancel the cruise.

Try adjusting it first yeah.

The plunger is on a ratcheting type travel, if you press the pedal down by hand and then pull the plunger out, then release the pedal slowly to bring the plunger in a few clicks.

You can also fine tweak it by hand by a click or two.

 

[SharpyClio]

Yeah defo check the brake switch first. I didn’t have a closed signal on that though just the one noted above.

I thought it was possible to adjust. Is that the same for the clutch switch too and the same across the board of models?

You can adjust both the clutch and brake switch by hand. Easiest way to take them out, only a quarter turn and the connector for each. Then you just do as @JamesBryan says with the plunger.

Thanks Guys
