What type of fuse does Brz use?
The Subaru BRZ, a popular sports car known for its sleek design and performance, relies on a variety of fuses to protect its electrical systems. Understanding the type of fuse your BRZ uses is essential for proper maintenance and quick troubleshooting of electrical issues. In this article, we’ll explore the types of fuses used in the BRZ and provide tips for replacing them safely.
Types of Fuses in the Subaru BRZ
The Subaru BRZ uses standard automotive fuses, which are designed to protect the car's electrical circuits from overloading or short-circuiting. These fuses are typically located in two main areas: the engine bay fuse box and the interior fuse box. Here are the common types of fuses you’ll find in the BRZ:
- Blade Fuses: These are the most common type of fuses in the BRZ. They come in various amperage ratings, such as 10A, 15A, 20A, and more, and are color-coded for easy identification.
- Mini Blade Fuses: A smaller version of the standard blade fuse, these are used for circuits that require less current.
- High-Amperage Fuses: These larger fuses are typically found in the engine bay and are used to protect high-current circuits, such as the alternator or main power supply.
Each fuse is designed to handle a specific amount of current. If the current exceeds the fuse's rating, the fuse will blow, cutting off the circuit to prevent damage to the electrical components.
How to Identify and Replace a Blown Fuse
If you suspect a blown fuse in your Subaru BRZ, follow these steps to identify and replace it:
- Locate the Fuse Box: The BRZ has two fuse boxes. One is located under the hood in the engine bay, and the other is inside the car, typically near the driver’s side footwell.
- Check the Fuse Diagram: Refer to the fuse box cover or the owner’s manual to identify the specific fuse associated with the malfunctioning component.
- Inspect the Fuse: Remove the suspected fuse using a fuse puller or a pair of needle-nose pliers. Check if the metal strip inside the fuse is broken or burned. If it is, the fuse is blown.
- Replace with the Correct Fuse: Replace the blown fuse with a new one of the same amperage rating. Using a fuse with a higher or lower rating can cause electrical issues or damage.
After replacing the fuse, test the component to ensure it is functioning properly. If the new fuse blows immediately, there may be an underlying electrical issue that requires professional diagnosis.
Tips for Maintaining Your BRZ’s Electrical System
To keep your Subaru BRZ’s electrical system in top condition, consider the following tips:
- Regularly inspect the fuse boxes for signs of corrosion or damage.
- Keep spare fuses of various amperage ratings in your car for emergencies.
- Avoid overloading electrical circuits by using accessories within their recommended limits.
- Consult a professional mechanic if you experience recurring electrical issues.
By following these tips, you can ensure the longevity and reliability of your BRZ’s electrical system.
Conclusion
The Subaru BRZ uses a combination of blade fuses, mini blade fuses, and high-amperage fuses to protect its electrical circuits. Knowing how to identify and replace a blown fuse is a valuable skill for any BRZ owner. If you’re ever unsure about handling electrical issues, don’t hesitate to consult a professional mechanic for assistance.

Frequently Asked Questions
What type of fuse do I need for my car?
To determine the type of blade fuses your vehicle uses, check your owner's manual for a fuse box diagram. A fuse box diagram will show you what kind of fuse goes into each slot and the exact amperage to use. If you are unable to locate a fuse box diagram, consult with your local auto mechanic.
What fuses are always on in a car?
A constant fuse, also known as a "hot at all times" fuse, is a fuse that maintains power even when the car is turned off. A switched fuse, on the other hand, only has power when the car is turned on.
What happens if you use a 20 amp fuse instead of a 15 amp fuse?
A fuse with a higher amp rating than it should have lets more current into the circuit that the components can handle. This could lead to overheating and device failure.
What are PAL fuses?
The PAL fuse series is used primarily in Japanese & Domestic designed car models to provide wiring harness protection. This fuse is a direct factory replacement for fusible link. Currently available in three styles: PAL Bent Terminal (bolts into fuse block), Female & Male Terminations.
Can I use a 10 amp fuse instead of 15 in my car?
A: Yes you can.
How do I know what type of fuse my car uses?
The most straightforward is to inspect the fuse itself, where the amperage rating is typically noted on or near the top of the fuse. The second is to check the fuse diagram in the vehicle, to understand which fuse type is in each slot.
What are class J fuses used for?
Class J Fuses:
Primarily used in control circuits, branch circuits, and motor control centers where compact size and high interrupting capacity are important.
Can you use a 13 amp fuse instead of 10?
As a rule of thumb, fuses are rated according to the power rating of the appliance. If you have to replace a fuse, it's essential, having checked and corrected the reason for the fuse blowing, to replace it only with another of the same rating.
How do I know what type of fuse to use?
The simple calculation is watts divided by volts equals amps. After you have calculated this, it is a simple case of adding around 10% to the value and choosing the nearest fuse to match.
