The primary power supply circuits of the electrical equipment in this hybrid vehicle are protected by fuses. High-current consumers are connected via relays. These protective components are installed in the passenger compartment, under the hood, and in the luggage compartment.
The information provided in the diagrams applies to first-generation Chevrolet Volt models (Delta II platform; model years 2010–2015).
Luggage Compartment
The fuse and relay block is located on the left side of the luggage compartment, behind the trim panel.
