Multiecuscan

just to add that I read on some US forum that above 3 % the cruise control can't be engaged, if I consider an used 175/65R15 compared to a recent 185/65 I am around 3.5-3.9%, so I hope!!!

SOLVED, I changed my font tyres by new ones same dimension as rear and the cruise control works perfectly. I assume that in the ECU software, there is a comparison between front/rear wheel speed and if the difference is too big cruise control refuses to engage.

Hello guys!

I know this is an old thread and discussed many many many times. But all links to wiring diagrams don't work anymore does anyone have them saved? I have an 2008 Grande punto with no cable on the steering colum.
I have been searching for a week now and cant find any wiring diagrams for the cruise control?
All french and italian sites are down so absolutley no luck with wiring diagrams... I have a friend that can activate the function but first i need to wire the cables. I have a schematic of the stalk and resistors so i can make a dummy stalk to test before buying a new one.

Any info greatly apriciated and again sorry for the never ending questions.

Thank you!

Hi,
i've add new pict on the french site:

I still miss some but you need to connect the pin 8 of cruise control level to the pin 41 of the D connector.

Hmmm... The link you specified directs me to a login page... It seem the forum is undergoing some changes and i can't register :/
Yes I saw some posts regarding this cable... It seems that the grande uses only one wire for all of the commands from the cruise control lever. I have the wrong schematic of the lever... I have it for the old punto and not for grande... ThePunto uses 4 lines.. Every bitton has its own input... But the Grande uses only one.. And each button has its own resistor so the voltage on that line varies...
Does anyone know the voltages for each button or resistances for each button... I want to make a dummy lever first.. So i know it works so i dont throw away 200€
Thank you!

Sorry i only have the wire for the grande punto , who only need one wire .

Hi,

Greetings to everyone.

I own Indian Abarth (A crossover variant of Punto) with me. It's body computer number is 51966727.
