Your 9th gen Civic (FB2 sedan, FB6 Si sedan, FG3 coupe, FG4 Si coupe) has two fuse boxes: one in the passenger compartment (under the driver’s side dashboard) and one in the engine compartment (on the driver’s side fender, next to the Brake Fluid reservoir).
Here’s the critical thing most universal fuse references get wrong: Honda did a major electrical redesign for the 2014-2015 facelift when they introduced Smart Entry (keyless access). The under-Hood fuse box was completely reworked. If you open a 2012 diagram for your 2014 Civic, you won’t find half the fuses you need.
This guide breaks down the pre-facelift (2012-2013) and facelift (2014-2015) separately — so you don’t waste time looking for fuses that don’t exist on your car.
Quick Reference — Where to Find the Fuse Boxes
| Location | Position | Notes |
|---|---|---|
| Under-Dash (Interior) | Under the steering column, above the pedals | You’ll still be lying on your back, but the diagram is now printed on the side panel of the dash — way easier to read than the 8th gen. |
| Engine Bay | Driver’s side fender, next to the brake fluid reservoir | Cover plastic is tougher than 8th gen, but clips still hate cold weather — open carefully. |
The Big Difference — 2012-2013 vs 2014-2015
⚠️ Don’t use the wrong diagram!
2012-2013 (Pre-Facelift): Traditional fuse layout. No Smart Entry system.
2014-2015 (Facelift): Completely redesigned under-hood fuse box. New Smart Entry fuses added. Headlight fuses moved to different positions.
Check your production date — if your car was built after mid-2013, use the 2014-2015 diagrams.
Passenger Compartment Fuse Box (Under-Dash) — All Years
Location: Under the dashboard, driver’s side — above the pedals.
2012-2013 (Pre-Facelift)
| № | Amps | Circuit Protected | Common Failure |
|---|---|---|---|
| 4 | 15 A | Fuel Pump | ⛽ Engine cranks but won’t start? Check this first. Fuel pump fuse is the #1 no-start culprit on 9th gen. |
| 27 | 15 A | Front Cigarette Lighter / Power Outlet | 🔌 The #1 blown fuse overall. Cheap phone chargers and dashcams kill this one constantly. |
| 12 | 15 A | Center Console Power Outlet | If the armrest 12V socket is dead but the front one works — it’s this fuse. |
| 6 | 15 A | Power Windows | If all windows are dead, this is the main fuse. Individual windows have separate 20A fuses (#14-#17). |
| 14 | 20 A | Driver’s Power Window | — |
| 15 | 20 A | Passenger’s Power Window | — |
| 16 | 20 A | Rear Left Power Window | — |
| 17 | 20 A | Rear Right Power Window | — |
| 5 | 10 A | Turn Signals / Hazard Lights | Blinkers dead? This is the first place to look. |
| 7 | 10 A | Brake Lights / Stop Switch | 🛑 Brake lights not working? Also affects shift interlock on automatics — shifter stuck in Park? Check this. |
2014-2015 (Facelift)
| № | Amps | Circuit Protected | Common Failure |
|---|---|---|---|
| 4 | 15 A | Fuel Pump | ⛽ Same as pre-facelift. Still the #1 no-start fuse. |
| 27 | 20 A | Front Cigarette Lighter / Power Outlet | 🔌 Honda bumped this from 15A to 20A because 15A fuses kept blowing from tire inflators and high-power accessories. |
| 12 | 20 A | Center Console Power Outlet | Also upgraded to 20A in the facelift. |
| 31 | 10 A | Smart Entry / Keyless Access | 🔑 NEW for 2014-2015. If the car doesn’t recognize the key and won’t turn on, check this first. |
| 6 | 15 A | Power Windows | Same as pre-facelift. |
| 14-17 | 20 A | Individual Power Windows | Same as pre-facelift. |
| 5 | 10 A | Turn Signals / Hazard Lights | Same as pre-facelift. |
| 7 | 10 A | Brake Lights / Stop Switch | Same as pre-facelift. |
Engine Compartment Fuse Box — Pre-Facelift (2012-2013)
Location: Driver’s side Fender, next to brake fluid reservoir.
| № | Amps | Circuit Protected | Common Failure |
|---|---|---|---|
| Multi-Fuse | 80 A / 100 A | Main Battery Fuse (bolted) | 🔧 DO NOT yank with pliers. Bolted down. Blows only when someone reverses battery polarity during a jump-start. |
| 1 | 70 A | EPS (Electric Power Steering) | 🔄 Steering wheel feels like concrete? This fuse is blown or the EPS module is dead. |
| 4 | 10 A | Headlight Low Beam (Left) | If one low beam is out and the bulb is good — this is the fuse. |
| 6 | 10 A | Headlight Low Beam (Right) | Same as #4 — one fuse per side. |
| 11 | 7.5 A | Oil Level Sensor | ⚠️ Known 9th gen issue. The wiring to the oil level sensor runs under the oil pan and gets damaged by rocks or road salt. Fuse blows, and you get a false oil warning on the dash. |
| 13 | 20 A | Horn | Horn not working? Check this before replacing the horn itself. |
| 15 | 30 A | ABS Pump (VSA) | If the ABS light is on and the pump doesn’t prime, check this. |
| 25 | 7.5 A | A/C Compressor (MG Clutch) | ❄️ A/C not engaging? Check this fuse. If it keeps blowing, the compressor clutch is seized. |
| 27 | 20 A | Tail Lights / Parking Lights | If the taillights are dead but brake lights work — check this and the bulbs. |
Engine Compartment Fuse Box — Facelift (2014-2015)
Location: Driver’s side fender, next to brake fluid reservoir.
⚠️ CRITICAL: The under-hood fuse box was completely redesigned for 2014-2015.
If you have a facelift car (2014-2015), DO NOT use the 2012-2013 diagram. Fuse positions changed. Headlight fuses moved. Smart Entry fuses added.
| № | Amps | Circuit Protected | Common Failure |
|---|---|---|---|
| Multi-Fuse | 80 A / 100 A | Main Battery Fuse (bolted) | 🔧 Same as pre-facelift. Bolted down — don’t yank it. |
| 1 | 70 A | EPS (Electric Power Steering) | 🔄 Steering dead? This fuse or the EPS module. |
| 20 | 15 A | Headlight Low Beam (Right) | 💡 MOVED in facelift. Right low beam is now #20 (was #6 in pre-facelift). |
| 23 | 15 A | Headlight Low Beam (Left) | 💡 MOVED in facelift. Left low beam is now #23 (was #4 in pre-facelift). If you check the old #4 slot and it’s empty — you’re looking at the wrong diagram. |
| 11 | 7.5 A | Oil Level Sensor | ⚠️ Same as pre-facelift. The oil level sensor wiring still gets damaged under the oil pan. Common failure. |
| 13 | 20 A | Horn | Same as pre-facelift. |
| 15 | 30 A | ABS Pump (VSA) | Same as pre-facelift. |
| 25 | 7.5 A | A/C Compressor (MG Clutch) | ❄️ Same as pre-facelift. A/C clutch fuse — check this if the A/C won’t engage. |
| 27 | 20 A | Tail Lights / Parking Lights | Same as pre-facelift. |
| 2 | 15 A | ACG Fuse (Alternator / Generator) | 🔋 Critical. If this fuse blows, the battery stops charging. Car will run until the battery dies, then leave you stranded. |
Garage Secrets — 9th Gen Specific Electrical Issues
⚠️ The Oil Level Sensor Wire Trap
On both R18Z1 and K24Z7 engines, the oil level sensor wiring runs along the bottom of the oil pan. In northern states with road salt, the wire insulation rots. In any state, rocks can puncture the harness.
Symptom: Fuse #11 (7.5A) under the hood keeps blowing, and the dash shows a false low oil warning even when the oil is full.
Fix: Jack up the car, inspect the wiring at the oil level sensor (located on the side of the Oil Pan). Repair or replace the damaged section. Do not just keep replacing the fuse — you have a short to ground.
💡 Headlight Stalk Switch Short
If the tail light fuse (#34 interior or #27 under-hood) keeps blowing for no obvious reason, the problem is often the headlight stalk switch itself — not the bulbs or wiring.
The switch shorts internally, causing a direct ground fault. Before you start chasing wiring, try replacing the turn signal / headlight stalk assembly. It’s a known 9th gen issue.
🔧 Smart Entry Problems? Check Fuse #31
On 2014-2015 facelift models, the Smart Entry (keyless access) system has its own 10A fuse (#31) in the interior fuse box.
If the car won’t recognize the key fob, won’t unlock doors with the door handle touch sensor, or won’t start with push-button — but the key fob battery is good — this fuse is your first suspect.
Pro tip: This fuse also powers the steering lock motor. If it blows, the steering wheel stays locked and the car won’t start AT all.

❓ 9th Gen Civic Fuse Box — Frequently Asked Questions
1. Why did both cigarette lighters die on my 2014 Civic Si?
On 2014-2015 models, the front outlet is fuse #27 (20A) and the center console outlet is fuse #12 (20A). Check both. Honda upgraded from 15A to 20A in the facelift because 15A fuses couldn’t handle high-power tire inflators.
2. Where is the low beam fuse on a 2015 Civic with push-button start?
Under the hood, driver’s side. Left low beam is fuse #23 (15A), right low beam is fuse #20 (15A). Do not use the 2012-2013 diagram — those fuses moved in the facelift.
3. What does the ACG fuse (#2) do?
The ACG fuse (sometimes labeled “Alternator” or “Generator”) protects the charging circuit. If this fuse blows, the battery stops charging and the car will eventually die. Check this if the battery light is on but the alternator is good.
4. Where is the 9th gen Civic interior fuse box located?
Under the dashboard on the driver’s side, above the pedals. The diagram is printed on the side panel of the dash — much easier to read than older generations.
5. Where is the 9th gen Civic engine bay fuse box located?
On the driver’s side fender, next to the brake fluid reservoir. Same location as 8th gen, but the fuse box itself is different.
6. Which fuse is for the fuel pump on a 9th gen Civic?
Fuse #4 (15A) in the interior fuse box. This is the #1 no-start fuse on the 9th gen.
7. Why does my oil warning light keep coming on even though the oil is full?
This is a known 9th gen issue. The oil level sensor wiring under the oil pan gets damaged by rocks or road salt, causing a short. The fuse #11 (7.5A) under the hood blows and triggers a false oil warning. Check the wiring at the oil level sensor.
8. What is the Smart Entry fuse on a 2015 Civic?
Fuse #31 (10A) in the interior fuse box. If the car won’t recognize the key fob, won’t unlock with the touch sensor, or won’t start with push-button — check this.
9. Why does my 2013 Civic keep blowing the tail light fuse?
If the taillight fuse (#34 interior or #27 under-hood) keeps blowing, the problem is often the headlight stalk switch itself — not the bulbs. The switch shorts internally. Replace the stalk assembly.
10. What is the main fuse amperage on a 9th gen Civic?
The main battery fuse is rated at 80 A or 100 A (depending on trim) and is bolted into the under-hood fuse box. Do not pull it without loosening the bolts.
💡 Pro tip: 2014-2015 facelift models have a completely different under-hood fuse box than 2012-2013. Always check your production date or VIN before using a diagram. If your VIN has an “F” in the 10th digit (2015) or “E” (2014), use the facelift diagrams.
Sources: Honda factory service manual, owner’s manual, and verified against real-world owner experience from 9th Gen Civic forums. Fuse assignments may vary by trim and market. Always verify with your owner’s manual.
