- Secured with a cover that can be removed by releasing clips or screws.
- Contains large fuses and relays.
Layout of the Main Fuse Box
The fuse box contains multiple slots, each assigned to specific functions. The diagram printed on the cover or in the vehicle's manual helps identify each fuse.
Typical Fuses and Relays in the Main Fuse Box:
- Engine Control Module (ECM) Fuse
- Fuel Pump Fuse
- Main Relay
- Cooling Fan Relay
- Horn Fuse
- Headlight Fuses
- Powertrain Control Module (PCM) Fuse

Interior Fuse Box (Cabin)
Located inside the vehicle, usually beneath the dashboard on the driver's side or in the glove compartment, the interior fuse box manages secondary systems.
Location and Access
- Found beneath the dashboard or behind a cover on the driver's side.
- The cover can be removed to access the fuse layout.
- Contains smaller fuses and sometimes relays.
Layout of the Interior Fuse Box
The interior fuse box's diagram is often printed on the cover or included in the owner’s manual.
Common Fuses in the Interior Fuse Box:
- Audio System Fuse
- Lighting Fuses (Interior, Dome Light)
- Power Windows and Door Locks
- Climate Control System
- Accessory Power Outlets (12V)
- Instrument Panel Lights

Understanding Fuse Labels and Amperage Ratings
Fuses are rated by amperage, indicating the maximum current they can handle before blowing to protect wiring and components.
Common Fuse Ratings in RSX
- 10A, 15A, 20A, 30A are typical.
- Using a fuse with a higher rating can cause electrical damage.
- Always replace with the same amperage as specified.
Identifying Fuses and Their Functions
- The fuse box cover or diagram provides labels or a legend.
- Most fuses are transparent, allowing visual inspection.
- A blown fuse appears blackened or broken.

Troubleshooting and Replacing Fuses
Proper maintenance of the fuse system ensures reliability and safety.
Steps for Troubleshooting
- Identify the affected system (e.g., headlights, radio).
- Check the corresponding fuse in the interior or main fuse box.
- Remove the fuse carefully using a fuse puller or pliers.
- Inspect the fuse for a blown filament or discoloration.
- If blown, replace with a fuse of the same amperage.
- Test the system to confirm the fix.
Tips for Fuse Replacement
- Always turn off the vehicle before replacing fuses.
- Use high-quality fuses from reputable brands.
- Keep spare fuses in the vehicle for emergencies.
- If a new fuse blows immediately, consult a professional as there may be an underlying electrical issue.

Additional Electrical Components Protected by Fuses
Beyond the basic systems, the RSX's fuse boxes also safeguard:
- Power Mirrors
- Sunroof (if equipped)
- Rear Window Defroster
- Alarm and Security Systems
- ECU and Sensor Modules
Understanding which fuse controls these components helps in targeted troubleshooting.
