Fuse box diagram (fuse layout), location, and assignment of fuses and relays Infiniti QX56, QX80 (Z62) (2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017).
Checking and Replacing Fuses
Fuses, fusible links, and circuit breakers protect your vehicle’s electrical system from overloading. If any electrical equipment in your vehicle does not operate, the system may have been overloaded and blown a fuse or tripped a circuit breaker. Before you replace or repair any electrical parts, check the appropriate fuses or circuit breakers.
- Be sure the ignition switch is pushed to the OFF or LOCK position and the headlight switch is turned to OFF.
- Open the fuse box cover.
- Remove the fuse with the fuse puller. The fuse puller is located in the center of the fuse block in the passenger compartment.
- To check a fuse, look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse.
- If the fuse is open, replace it with an equivalent good fuse. Spare fuses are stored in the passenger compartment fuse box.
- If a new fuse also opens, have the electrical system checked and repaired by an INFINITI dealer.
In case if the electrical equipment does not operate and the fuses are in good condition, check the fusible links. In case if any of these fusible links are melted, replace them with only genuine INFINITI parts.
Notice
- Never use a fuse of a higher or lower amperage rating than that specified on the fuse box cover. This could damage the electrical system or cause a fire.
- Always disconnect the battery before servicing high current fuses.
- Never replace a broken fuse with anything other than a new fuse. Use always an intact fuse of the same color.
