The Honda Fit for the Japanese domestic market (JDM)—marketed in Europe as the Honda Jazz—has been in production since June 2001, maintaining high sales volumes and strong popularity. This subcompact combines minivan-like versatility with sporty styling. The North American market version debuted at the Detroit Auto Show in January 2006. This article provides a detailed breakdown of the fuse box diagrams and relay assignments for the first-generation (GD chassis) model years 2001, 2002, 2003, 2004, 2005, 2006, and 2007.
Below you will find fuse box locations, diagrams, and photo references. The fuses protecting the “Cigarette Lighter” (Accessory Socket) and “Fuel Pump” circuits are highlighted in bold.
