Most electrical power circuits in this vehicle are protected by fuses. High-current consumers, such as the headlights, cooling fan motors, and fuel pump, are switched via relays. Protective fuses and relays are housed in power distribution boxes located in the passenger compartment and engine compartment.
Applicable models: 1st-Generation Infiniti QX60 (chassis code L50) – Model Years 2012, 2013, 2014, 2015, 2016, 2017.
