Renault uses French acronyms even on English versions. For example:

| Task | Benefit from VISU | |------|------------------| | Fault finding – no communication with an ECU | Shows power, ground, and bus wiring in clear isolation. | | Retrofit of equipment (e.g., fog lights, towbar) | Identifies existing pre‑wiring and correct splice points. | | Intermittent electrical issues | Provides full circuit routing to locate potential chafing or corrosion points. | | Short circuit or open circuit diagnosis | Every wire gauge, color, and path is documented. |
