How to Replace Fuse: 2023 Kia Niro PHEV Fuse Diagrams Guide

Changing the switch in your 2023 Kia Niro PHEV is a simple job that can be done with little trouble. To find the fuse you need to change, start by looking at the fuse box cover or the fuse diagram in your car’s manual. Once the problem has been found, make sure the car’s ignition is off to avoid any electricity problems. Handle the broken fuse with care by firmly gripping it and pulling it straight out of its hole with a fuse puller or needle-nose pliers. Check the fuse to make sure it’s blown; a broken wire inside will show you this. Next, put a new fuse with the same amperage rating into the empty slot and make sure it’s firmly in place. After that, put the fuse box cover back on, turn the key back on, and test the electrical part to make sure it works right. By following these easy steps, you can quickly and easily replace a fuse in your Kia Niro PHEV. This will keep your car’s electrical systems running smoothly.

Fuses

• Left side: Normal, Right side: Blown
• The actual fuse/relay panel label may differ from the equipped items.

A vehicle’s electrical system is protected from electrical overload damage by fuses.
This vehicle has 2 (or 3) fuse panels, one located in the driver’s side panel bolster, and the other in the engine compartment near the battery.
If any of your vehicle’s lights, accessories, or controls do not work, check the appropriate circuit fuse. If a fuse has blown, the element inside the fuse will melt. If the electrical system does not work, first check the driver’s side fuse panel.
If the replacement fuse blows, this indicates an electrical problem. Avoid using the system involved and immediately consult an authorized Kia dealer. Three kinds of fuses are used: blade type for lower amperage ratings, cartridge type, and multi fuse for higher amperage ratings.

WARNING

Fuse replacement

• Never replace a fuse with anything but another fuse of the same rating.
• A higher capacity fuse could cause damage and possibly a fire.
• Never install a wire or aluminium foil instead of the proper fuse – even as a temporary repair. It may cause extensive wiring damage and a possible fire.
• Do not arbitrarily modify or add electric wiring to the vehicle.

CAUTION
Do not use a screwdriver or any other metal object to remove fuses because it may cause a short circuit and damage the system.

NOTICE

• When replacing a fuse, turn the ignition ‘OFF’ and turn off switches of all electrical devices then disconnect the (-) battery terminal (For plug-in hybrid vehicle) or battery connector (For hybrid vehicle).
• Window tinting precaution
  Window tint (especially metallic film) might cause communication disorder or poor radio reception, and malfunction of the automatic lighting system due to excessive change of illumination inside the vehicle. The solution used might also flow into electric, and electronic devices causing disorder and failure.
• Window tinting precaution
  Window tint (especially metallic film) might cause communication disorder poor radio reception, and malfunction of the automatic lighting system due to excessive change of illumination inside the vehicle. The solution used might also flow into electric, and electronic devices causing disorder and failure.

WARNING

Electrical fire
Always ensure replacement fuses and relays are securely fastened when
installed. Failure to do so can result in a vehicle fire. Do not remove fuses, relays and terminals fastened with bolts or nuts. The fuses, relays and terminals may be fastened incompletely, and it may cause a possible fire. If fuses, relays and terminals fastened with bolts or nuts are blown, consult with an authorized Kia dealer.

CAUTION
When replacing a blown fuse or relay, make sure the new fuse or relay fits tightly into the clips. Failure to tightly install the fuse or relay may cause damage to the wiring and electric systems.

CAUTION

• Do not input any other objects except fuses or relays into fuse/relay terminals such as a screwdriver or wiring. It may cause contact failure and system malfunction.
• Do not plug in screwdrivers or after-market wiring into the terminal originally designed for fuse and relays only. The electrical system and wiring of the vehicle interior may be damaged or burned due to contact failure
• If you directly connect the wire to the taillamp or replace the bulb which is over the regulated capacity to install trailers etc., the inner junction block can get burned.

WARNING

Electrical wiring repairs
All electrical repairs should be performed by authorized Kia dealerships using approved Kia parts. Using other wiring components, especially when retrofitting multimedia or theft alarm systems, car phones or radios may cause vehicle damage and increase the risk of a vehicle fire.

NOTICE

4. Remove the Fuse: Using a fuse puller tool or a pair of needle-nose pliers, carefully remove the faulty fuse from its slot. Be gentle to avoid damaging the fuse or the fuse box.
5. Install the New Fuse: Take a new fuse of the same amperage rating and insert it into the slot where the old fuse was removed. Make sure it fits snugly into place.
6. Reconnect the Battery: If you disconnected the car battery earlier, reconnect it once the new fuse is in place.
7. Test the Component: Turn on the ignition and test the component associated with the fuse you replaced to ensure it’s functioning properly. If everything works as expected, you’ve successfully replaced the fuse.
8. Close the Fuse Box: Once you’ve confirmed that the replacement fuse is working, close the fuse box securely.
9. Dispose of the Old Fuse: Safely dispose of the old fuse. It’s a good idea to keep spare fuses in your car in case you need them in the future.

Tips:

• Always use a fuse with the correct amperage rating to prevent electrical issues or damage to the vehicle.
