Most electrical circuits in this Japanese minivan are protected by fuses. High-current consumers—such as headlights, cooling fan motors, and the fuel pump—are connected via relays. Protective components are housed in power distribution boxes located in the engine compartment and passenger compartment.
Applicable models: Honda Mobilio (Global Small Car platform; chassis code GB) produced from 2001 to 2008 (2WD & 4WD) equipped with the 1.5L L15A engine, as well as the Mobilio Spike (GK chassis).
