Every Honda Civic from the 7th generation onward uses two primary fuse boxes: one under the hood near the battery and one inside the cabin under the dashboard on the driver’s side. The 11th generation adds a third sub fuse box. When an electrical component stops working—power windows, the radio, the Fuel Pump, interior lights—the fuse box is the first place to check. Fuse locations are printed on the inside of each box cover. Always replace a blown fuse with one of the same amperage. Never use a higher-rated fuse as a substitute; doing so risks wiring damage or fire.
The tables below list the most commonly referenced fuses for each generation. Optional fuses (not installed on all trims) are shown in parentheses. Data sourced from Honda TechInfo owner’s manuals and verified against fuse-box.info and fubox.net.
7th Generation (2001–2005) — EM/EP/ES/EU
The under-Hood fuse box sits on the passenger side next to the battery. The interior fuse box is located underneath the steering column. The under-hood box handles high-current loads: cooling fans, headlights, ABS motor, rear defroster, and the main battery fuse (80 A). The interior box covers lower-current circuits: power windows, door locks, the cigarette lighter (fuse #18), and interior lighting.

The interior fuse box on the 7th gen covers power windows (20 A each), door locks, interior lighting, and the accessory power socket (cigarette lighter, fuse #18 in the interior box). Spare fuses (7.5 A–30 A) are stored in slots 21–25 of the under-hood box.
8th Generation (2006–2011) — FA/FD/FG
The 8th gen introduced a more complex electrical architecture with the MICU (Multiplex Integrated Control Unit) body electronics module. Many fuses in the interior box now feed through the MICU, which means a blown fuse can affect multiple seemingly unrelated systems. The under-hood box is on the driver’s side near the battery on USDM models. The interior box is under the dashboard to the left of the steering column.
Key circuits to know: the audio system and front accessory socket share separate 20 A fuses (fuses #28 and #29 in the interior box). The sunroof is fuse #24 (20 A). Daytime running lights are fuse #37 (7.5 A). The wiper motor is fuse #38 (30 A). TPMS is fuse #7.5 A in the interior box. On Coupe models, the audio amplifier has its own dedicated fuse.

The 8th gen engine compartment box handles the EPS motor, ABS/VSA motor, ignition main, rear defroster, blower motor, and headlight main relays. The ECM/PCM fuse is 15 A (fuse #2 in the under-hood box). On Si models, the same fuse box layout applies; the Si-specific circuits (VTEC solenoid, oil pressure) are fed through the ECM fuse Chain.
9th Generation (2012–2015) — FB/FG
The 9th gen fuse layout is sourced directly from the 2013 Honda Civic owner’s manual (Honda TechInfo). The engine compartment fuse box is located near the Brake Fluid reservoir. The interior fuse box is under the dashboard; fuse locations are shown on the label on the side panel. The main battery fuse is 100 A. The EPS fuse is 70 A. The ABS/VSA motor fuse is 30 A. The blower motor fuse is 40 A.

10th Generation (2016–2021) — FC/FK
The 10th gen fuse layout is sourced from fubox.net (2016–2021 USDM). The interior fuse box is under the dashboard to the left of the steering column. The engine compartment fuse box is near the battery on the driver’s side. Key changes from the 9th gen: the smart entry system (keyless access) adds a dedicated 10 A fuse; the front sensor camera (Honda Sensing) gets its own 5 A fuse; the CVT transmission control adds a 10 A fuse. The accessory power socket fuse is fuse #29 (20 A) in the interior box.

The 10th gen engine compartment box carries the same high-current architecture as the 9th gen: Battery main fuse 125 A, EPS 70 A, ABS/VSA motor 30 A, IG Main 30 A (with smart entry) or 50 A (without), Fuse Box Main 60 A, Headlight High Beam Main 30 A, Rear Defroster 30 A, Blower Motor 40 A. The Cooling Fan fuse is 30 A (1.5T) or 50 A (2.0T Si).
11th Generation (2022–2025) — FE/FL
The 11th gen is the most complex Civic fuse layout to date. It has three separate fuse boxes: the engine compartment box (near the battery), the interior box (under the dashboard, left of the steering column), and a sub fuse box. The sub fuse box handles backup circuits, audio VST, and accessory voltage stabilizer circuits. Fuse locations are shown on the box cover (engine compartment) and on the label under the steering column (interior). Data sourced from Honda TechInfo (2022 Civic Sedan owner’s manual) and StartMyCar.

The 11th gen sub fuse box handles voltage stabilizer circuits (VST 1, VST 2, ACC VST, AUDIO VST), backup circuits (BACKUP2 MAIN), and optional audio sub VST. These are low-current fuses (7.5–15 A) that support the 11th gen’s expanded infotainment and driver-assist electronics.
How to Find and Replace a Blown Fuse
Turn the ignition off before checking fuses. Open the fuse box cover—the diagram on the inside of the cover shows each fuse’s number and rating. Use the fuse puller stored on the back of the engine compartment fuse box cover (all generations). Pull the suspect fuse straight out and hold it up to light: a blown fuse has a visibly broken metal strip inside. Replace with a fuse of the same amperage only. If the new fuse blows immediately, there is a short circuit in that circuit—do not keep replacing fuses without diagnosing the underlying fault.
Spare fuses are stored in the engine compartment fuse box on all generations. The 7th gen stores spares in slots 21–25. On 8th through 11th gen models, spare fuses are in a dedicated spare slot section of the under-hood box. Always carry a spare assortment of 7.5 A, 10 A, 15 A, and 20 A mini blade fuses—these cover the vast majority of Civic circuits across all generations.
Common Fuse-Related Problems by Generation
On 8th gen Civics, a failed MICU can cause multiple fuses to appear blown when the module itself is the fault. If several unrelated circuits fail simultaneously—door locks, interior lights, and windows together—suspect the MICU before replacing individual fuses. On 9th gen models, the accessory power socket fuse (fuse #12, 20 A, interior box) is a frequent failure point when aftermarket chargers or dash cams draw sustained current above the fuse rating. On 10th gen models, the Honda Sensing camera fuse (5 A) is sensitive to voltage spikes from aftermarket accessories wired into the same circuit. On 11th gen models, the sub fuse box VST circuits can cause intermittent infotainment resets if the audio amplifier fuses (55–56, 30 A each) are undersized for aftermarket amplifier loads.
Adding aftermarket accessories—dash cams, radar detectors, USB hubs—always tap into a switched 12 V circuit rated for the load. The front accessory socket fuse (20 A) is the most common tap point, but it is shared with the socket itself. A better approach is to use the option fuse slot (where present) or wire directly to the interior fuse box with an add-a-fuse adapter, keeping the total draw under 80% of the fuse rating.
