Fuses and relays Volvo XC90 (C / 275), 2002–2014

The first-generation Volvo XC90 luxury crossover was introduced in 2002. Alongside the S60, V70, and S80 models, it was built on the Volvo P2 platform. At the time of its release, it was the largest crossover produced by the manufacturer. In this article, we provide a detailed overview of the fuse box diagrams for the first-generation Volvo XC90 (codename C; chassis code 275; P2 platform), covering model years 2002 through 2014.

Below, you will find the locations and illustrations of the power distribution boxes. The fuses protecting the “Cigarette Lighter” and “Fuel Pump” circuits are highlighted in bold.

Power Distribution Box Layout

The power distribution boxes are situated in four primary locations:
1. In the engine compartment.
2. In the passenger compartment, behind the acoustic trim panel on the driver's side.
3. In the passenger compartment, at the edge of the dashboard on the driver's side.
4. In the luggage compartment.
