The first generation of Volvo's compact executive sedan, the S40, was developed in collaboration with Japan's Mitsubishi and shared a platform with the Carisma, both models being produced at the NedCar plant in the Netherlands. However, despite sharing a common platform, approximately 4,000 of the S40's 5,000 components were unique. In this article, we will take a detailed look at the fuse box diagrams for the Volvo S40 (1st generation; chassis code VS / 644) for model years 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, and 2004.
Below you will find the locations, diagrams, and photographs of the power distribution boxes. Fuses protecting key circuits such as the "Cigarette lighter" and "Fuel Pump" are highlighted in bold.
Passenger Compartment
Two power distribution boxes responsible for protecting interior electrical circuits are located in this area.
Fuse Box
