Fuses and relays Toyota Ipsum (ACM20; 2001-2009)

Most of the electrical circuits in the electrical equipment of the Japanese minivan are protected by fuses. Headlights, fan motors, fuel pump and other powerful current consumers are connected via relays. Protective elements are installed in distribution boxes, which are located in the engine compartment and the passenger compartment.

Fuse circuits are relevant for Toyota Ipsum (ACM20) cars 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009 release with gasoline engines 1AZ-FE and 2AZ-FE.
