VW Passat 3C ACC Control Unit CAN Database

Hi,

Does anyone have access to a CAN database for the J428 'Distance Control Unit'?
Has anyone experimented with this before and managed to decode any messages?
I'm mainly interested in the messages related to activating the ACC (Adaptive Cruise Control).

If it would be helpful, I can also upload a list of messages that are sent from the vehicle to the ACC control unit and vice versa.


Sure, here's the translation:

'Hello.'
Andi.

Does anyone have any ideas?

short answer - give me a car, and I will find everything that you need .
Unfortunately, I don't have any ACC (Adaptive Cruise Control) data specifically for that exact car model; I only have data for more common features.

Well, "Does anyone have any ideas on how to get a CAN database?", but for what exactly?
So, one of the developers definitely won't contact you.

Okay, I have an idea: This system probably provides minimum distance values. You could simulate a car (using plywood, possibly covered with aluminum foil), and then observe which values on the CAN bus change when you alter the distance of the plywood sheet...

Best regards, Rainer.

"Edit: I'm not sure now if the ACC (Adaptive Cruise Control) is integrated in a similar way to how it is in the Audi A8, which would make simulating a vehicle more difficult. Should I start with Audi SSP 289, page 38?"
