Most electrical circuits in this vehicle are protected by fuses. High-current consumers—such as headlights, cooling fan motors, and the fuel pump—are operated via relays. Protective fuses and relays are housed in power distribution centers located in the engine compartment and passenger cabin.
This article provides detailed fuse box diagrams and relay assignments for the Nissan X-Trail (chassis code T31; C platform) produced from 2007 through 2015.
Engine Compartment
In the engine compartment, protective elements are housed in main fuse box A and secondary fuse box B, located beneath the air intake duct.
