In spring 2000, the Mitsubishi Lancer (CS platform) was introduced in Japan under the model name Cedia. The vehicle underwent a major facelift in 2003. This article provides detailed fuse box diagrams and relay panel layouts for the ninth-generation Mitsubishi Lancer (2001, 2002, 2003, 2004, 2005, 2006, and 2007 model years).
Below are the location diagrams, photos, and circuit assignments for the power distribution centers. Fuses for key circuits such as the “Cigarette Lighter” and “Fuel Pump” are highlighted in bold.
Engine Compartment Fuse Boxes
Three power distribution units located under the hood protect the vehicle’s primary electrical circuits.
Main Fusible Link
The main high-current fusible link is mounted directly on the positive battery terminal.
Main Engine Compartment Fuse Box
Located on the left side (driver side) of the engine compartment. It houses the main fuse block and an auxiliary relay panel.
