Volvo Diagnostics II - first version was a new Volvo standard introduced in 1996 . This meant that control modules communicated serially in the same way, and that diagnostic functions in the different systems were designed in a similar manner.

The communication cable in the vehicle used for this communication is common to all control modules in question. The control modules are connected to the same connection in the diagnostic socket (pin 7).

The diagnostic socket is located in the passenger compartment and for certain markets it is common with the diagnostics system OBD II.

Volvo Diagnostics II, first version, was introduced in 1996 on, among others:

Engine management system Motronic 4.4
Automatic transmission AW 50 42/AW 30 40/43
Control module Airbag SRS6.2
Immobilizer
Control module Brakes ABS 850
Combined instrument panel 850
Power seat 850/960
and was gradually introduced for additional systems and car models.

For certain models, the diagnostics tool for this diagnosis is still Volvo System Tester (car models from and incl. model year 1998 as well as certain systems for model year 1999).

The diagnostics tool VIDA, now replacing VADIS, is used for car models of model year 1999 and later.
