2020 ACURA ILX Fuses and Fuse Box | Replacing a blown fuse
The 2020 Acura ILX has a complex network of electrical parts that power its many functions. The fuses and the box that houses them called the fuse box, are very important for making sure that everything works smoothly and safely. The fuse box is an intentional center hub inside the car that holds a variety of fuses that protect different electrical circuits. Each fuse is a safety block that is meant to break the circuit if there is an electrical overload or problem. This keeps the vehicle’s sensitive electronics from getting damaged. Finding and changing a blown fuse is the first thing that you should do when you have an electrical problem. While this job may seem easy, it requires a good understanding of the electrical system and a good understanding of how the fuse box is organized in the vehicle. Let us look at the 2020 Acura ILX’s fuses and fuse box in more detail, including the steps needed to replace a blown fuse so that the car’s electrical parts continue to work properly.

Inspecting and Changing Fuses
- Set the power mode to VEHICLE OFF (LOCK). Turn headlights and all accessories off.
- Remove the fuse box cover.
- Check the large fuse in the engine compartment.
- If the fuse is blown, use a Phillips-head screwdriver to remove the screw and replace it with a new one.
- Inspect the small fuses in the engine compartment and the vehicle interior.
- If there is a blown fuse, remove it with the fuse puller and replace it with a new one.
Notice
Replacing a fuse with one that has a higher rating greatly increases the chances of damaging the electrical system.
Use the charts to locate the fuse in question and confirm the specified amperage on the fuse label.
Replace the fuse with a spare fuse of the same specified amperage.
There is a fuse puller on the back of the engine compartment fuse box cover.
