Diagnostics and fault tracing are carried out as before using VIDA.

However from the 1999 model year onwards the Volvo Scan Tool (ST) (which could only communicate serially via the data link connector (DLC)) has been replaced by a new communication unit called the VCT 2000 (Volvo Communication Tool 2000) which can communicate with the modules via the network.
