Fuses and relays (2010 - 2018) Infiniti M37 / M56 / Q70 / M35h

The power supply circuits for electrical equipment are protected by fuses and relays. The elements are installed in mounting blocks located in the engine compartment and in the passenger compartment.


The fuse diagrams of Infiniti M37, M56, Q70, M35h (Y51; 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018) are considered.

In the engine compartment


There are two fuse boxes on the left side of the engine compartment, and one relay box on the right.
