How to Replace the fuses of the 2021 Acura NSX

The 2021 Acura NSX has a reasonably simple fuse replacement procedure. Here’s a step-by-step manual to assist you with the procedure:

Replacement fuses (make sure they match the amp rating of the blown fuses) are required.

  • Needle-nose pliers or fuse puller
  • An optional flashlight to improve visibility

Instructions by Step

  1. Switch off the Ignition
    • Verify that the car is parked firmly and that the ignition is off.
  2. Find the Fuse Boxes
    • The Acura NSX (2021) normally has two fuse boxes: one in the engine compartment and another inside the car, usually in the kick panel or under the dashboard.
  3. Identify the Blown Fuse
    • To identify the fuse connected to the malfunctioning component, consult the fuse box diagram and owner’s manual. Examine the fuses visually for any discoloration or broken filaments.
  4. Remove the Fuse
    • Firmly grasp the blown fuse with a fuse puller or needle-nose pliers. Take it out of the slot straight away. Use caution when using pliers to prevent breaking the fuse or the fuse box.
  5. Inspect the Fuse
    • Verify the removed fuse is blown by checking it twice. Seek for indications of discoloration or a broken filament.
  6. Select a Replacement Fuse
    • Make sure the new fuse you installed has the same amp rating as the old one. A different amp rating could result in electrical problems.
  7. Insert the New Fuse
    • Position the replacement fuse in the slot and give it a gentle push. Make sure the fit is snug.
  8. Repeat if Necessary
    • If more than one fuse blows or if you think there may be others at risk, go through the steps again for each one.
  9. Secure the Fuse Box Cover
    • Attach the fuse box cover firmly after replacing the fuses. Verify that it is latching correctly.
  10. Reconnect the Battery (If Disconnected)
    • Reconnect the battery if you disconnected it for safety.
  11. Test the System
