Question Speed signal not working

Hi folks,

I connected the speed signal from the green/black wire from the passenger sill to the A pin 1 and C2 pin 6 connections for my command, but the infos screen still thinks the car isn't moving.

Anyone have any ideas, what the problem could be? Most mechanics I spoke to tilt their head sideways and go "What?"

Thanks,
LK.

What?

I know there's a way to have the AC unit display your speed lol. It's some kind of diagnostic thing that shows your AC pressure and so on. Maybe someome has a link to the thread or the page on that one mechanic's website.

Yep, I'm using the blue connector, green/black wire in the passenger sill.

Then you must validate that this wire is certainly connected to C2 pin 6. Once when i was in a hurry on my own car I managed to connect it to pin 5.

There would be no reason from this configuration for it not to work other than it being faulty at the COMAND end.
