Table of Contents
Most of the electrical circuits in this Japanese crossover are protected by fuses. High-current components—such as the headlights, cooling fan motors, and fuel pump—are switched via relays. Protective elements are housed in power distribution boxes located in the engine compartment and passenger cabin.
The diagram information applies to 3rd-generation Honda CR-V (chassis code RE) models produced for model years 2006, 2007, 2008, 2009, 2010, 2011, and 2012.
Passenger Compartment Fuse Box
The under-dash fuse box (1) is located on the driver’s side, at the lower portion of the dashboard. The fuse legend (2) is located underneath the steering column.
