Volvo Diagnostics II - second version
Volvo Diagnostics II - second version was introduced in 1999 and is a development of the first version. The major difference is that communication between the diagnostics tool and the control modules takes place via CAN-communication instead of on a communication cable.
The control modules also communicate with each other to exchange information on the CAN-net instead of via separate cables between the control modules.
This version introduced the possibility to download software to the control modules.
With the introduction of this version, the rate in the low-speed network was (LS CAN) 125 kbit/s and the rate in the low-speed network was (HS CAN) 250 kbit/s. Depending on model and model year, the speed of the network has increased with time.
For further information about CAN, see VIDA Design and Function, CAN-net as well as Design and Function, Downloading Software.
Volvo Diagnostics II, second version, was introduced in model V70 (00-) as well as V70 (-00) and thereafter in future models.
The diagnostics tool VIDA, now replacing VADIS, is used for car models of model year 1999 and later.
