2001 Civic Fuse Box Diagram: Understanding the Civic Fuse Boxes
Understanding the Fuse Boxes on 2001 Civic
The 2001 Honda Civic is part of the 7th generation of Civics. It is equipped with two fuse boxes: one located inside the vehicle and the other in the engine bay. In this article, I’ll display the 2001 Civic fuse box diagram for the under-dash and under-hood panels.
2001 Civic Fuse Box Diagram For The Under Dash Panel
The interior fuse box of the 2001 Honda Civic is located under the dashboard on the driver’s side, near the left kick panel. It can be accessed by removing the small cover that conceals the fuse box. This box’s fuses protect smaller powered devices like the radio, power windows, and dashboard lights.

2001 Civic Fuse Box Diagram For The Under Hood Panel
The engine bay fuse panel is located near the battery on the passenger side of the engine compartment. This more robust panel houses fuses and relays for essential systems like the engine control unit (ECU), cooling fans, and anti-lock brakes (ABS). Accessing this fuse box requires opening the black plastic cover, which clips hold in place.

Radio Caution When Checking Fuses or Replacing A Car Battery
Standard for LX and EX models in the U.S., and LX and Si models in Canada
If the radio fuse is removed, the audio system will disable itself. The next time you turn on the radio, you will see ‘‘COdE’’ in the frequency display. Use the preset buttons to enter the five-digit code.
To make it work again, enter a specific five-digit code in the preset buttons. Because there are hundreds of number combinations possible from five digits, making the system work without knowing the exact code is nearly impossible.
You should have received a card that lists your audio system’s code and serial numbers. It is best to store this card in a safe place at home. In addition, you should write the audio system’s serial number in this Owner’s Manual.
If you lose the card, you must obtain the code number from a dealer or the Honda Owner’s website. You will need the system’s serial number to do this.
Use the preset buttons to enter the five-digit code. If you make a mistake entering the code, do not start over; complete the five-digit sequence, then enter the correct code. You have ten tries to enter the correct code. If you are unsuccessful in ten attempts, you must then leave the system on for 1 hour before trying again.
How to find your radio serial number
1) Locate the Honda Radio Anti-Theft Card
The Radio/Navigation Code and the device unit’s serial number are listed on the
anti-theft ID card that comes with the vehicle. The card is usually placed in the glove box at the time of delivery.
2) Enter the Radio’s Serial Number on the Honda Website
Retrieve the Serial Number From the Radio Display
1. Turn the ignition switch to ON.
2. Turn ON the device and confirm that the display reads CODE. If you don’t see this message, pull the backup fuse for 1 minute, and then go back to step 1.
3. Turn OFF the device.
4. Press and hold the 1 and 6 radio preset buttons, and turn ON the device.
5. The display toggles between two screens: U with the first 4 digits of the serial number (U2200 for example,)
6. And L with the last 4 digits of the serial number (L0055 for example).
7. Ignore the U and L and record all 8 digits.
