Toyota Hilux Fuse Box: Location & Guide
TL;DR
Hilux fuses live in an engine-bay box near the battery and an interior box under the driver-side dash; the lid diagram and owner's manual are the only reliable maps of which fuse does what.
Where the Toyota Hilux fuse boxes are located
Every generation of the Hilux uses the same basic two-box layout. In the engine compartment, the main fuse and relay box sits beside or on top of the battery, usually under a black plastic cover held by clips or a couple of tabs you pry up with a fingernail or flat screwdriver. Inside the cabin, the interior fuse box is mounted under the dashboard on the driver's side, typically behind a small removable panel near the hood-release handle or just to the left of the steering column, sometimes low enough that you need to kneel or feel with your hand to find the release tab.
How to access each box
The engine-bay cover usually lifts straight up once the edge clips are released; no tools are needed on most model years, though a flathead screwdriver helps pry stubborn clips. The interior panel is normally a snap-fit cover that unclips by pulling the edge toward you, occasionally secured by one small screw. Never force a cracked or brittle cover; replace it if it no longer seats fully, since a loose lid lets moisture and dust reach the fuses.
| Generation / years | Fuse box | Location | How to access |
|---|---|---|---|
| 7th gen (2005-2015) | Engine bay | Beside the battery, engine compartment | Unclip the plastic cover; lift straight up |
| 7th gen (2005-2015) | Interior | Under dash, driver's side near hood release | Snap-fit panel, pull edge to release |
| 8th gen (2015-2023) | Engine bay | Next to the battery, engine compartment | Unclip cover; lift off |
| 8th gen (2015-2023) | Interior | Under dash, left of steering column | Small cover panel, pull to unclip |
| 9th gen (2023-present) | Engine bay | Beside the battery, engine compartment | Unclip cover; lift off |
| 9th gen (2023-present) | Interior | Under dash, driver's side lower panel | Snap-fit or single-screw panel |
Reading the fuse legend
Toyota prints the complete fuse map as a small diagram on the underside of each box lid, listing which slot feeds which circuit and its amp rating. This lid diagram is the only source you should trust for exact fuse positions and amperages, because Toyota changes the layout between trims, markets, and mid-cycle updates even within one generation. The owner's manual electrical or maintenance chapter repeats this same diagram in a larger, easier-to-read format, plus a legend of the abbreviations used.
Fuses that most commonly blow, by function
- Cigarette lighter / 12V accessory outlet - blows most often from phone chargers, inverters, or air compressors drawing more current than the circuit allows; symptom is simply a dead outlet with everything else working.
- Radio / infotainment - a blown fuse here kills the screen, sound, and sometimes the reversing camera feed at once, while climate and lights keep working normally.
- Interior lights - dome light, map lights, and glovebox light typically share one fuse; all going dark together points here.
- Blower motor (HVAC fan) - when this fuse blows, air stops moving through the vents even though the AC compressor and heater still technically work.
- Fuel pump relay / fuse - a blown fuse or failed relay here causes a no-start or the engine cranking but never catching, because the pump never pressurizes the fuel rail.
Checking and replacing a fuse safely
Pull the suspect fuse with the small plastic puller clipped inside the fuse box lid and look at the thin metal strip inside; a gap or scorch mark confirms it is blown. If the strip looks intact but you are unsure, a simple test light or multimeter across the two exposed prongs with the ignition on will confirm continuity. Replace a blown fuse only with one of the identical amp rating and color - never a higher rating, since the fuse is sized to protect the wiring, not just the component. If a fuse blows again shortly after replacement, stop swapping fuses: a repeatedly-blowing fuse almost always means a short circuit or failing component downstream, and running an OBD-II scan for stored fault codes at that point is the fastest way to narrow down which circuit is at fault before more wiring damage occurs.
Summary
| Engine-bay fuse box location | Beside/on top of the battery, engine compartment |
|---|---|
| Interior fuse box location | Under dash, driver's side, near hood release or left of steering column |
| Fuse legend source | Printed diagram under each box lid + owner's manual electrical chapter |
| Generations covered | 7th gen (2005-2015), 8th gen (2015-2023), 9th gen (2023-present) |
| Markets | Sold across Latin America, Brazil and other global markets; not sold in US/Canada |
| Golden rule when replacing | Always match the amp rating printed on the fuse - never go higher |
| Repeated blow warning sign | Points to a short circuit; check for stored fault codes before refitting again |

Frequently asked questions
Where is the fuse box on a Toyota Hilux?
There are two fuse boxes on every Hilux generation: one in the engine bay beside the battery under a clipped plastic cover, and one inside the cabin under the dashboard on the driver's side, usually behind a small panel near the hood-release lever or just left of the steering column. The exact fuse assignments for your specific year and trim are printed on the underside of each box's lid.
Why does my Hilux's cigarette lighter or 12V outlet fuse keep blowing?
The 12V accessory outlet fuse usually blows because a plugged-in device (phone charger, inverter, air compressor, dash cam) is drawing more current than the circuit is rated for, or because of a short in the accessory's own wiring. Replace the fuse with the exact same amp rating printed on the box lid; if it blows again immediately with nothing plugged in, that points to a wiring short rather than an overloaded accessory, and it is worth checking for stored fault codes.
How do I know which fuse controls a specific function in my Hilux?
Do not rely on generic online fuse-position lists, since Toyota changes exact slot assignments across trims and mid-cycle updates. The reliable source is the printed diagram on the underside of the engine-bay and interior fuse box lids, which matches your exact vehicle, plus the same diagram repeated in the owner's manual's electrical section.
What does it mean if a fuse in my Hilux blows repeatedly?
A fuse that blows again shortly after you replace it is not a coincidence - it almost always means there is a short circuit, chafed wire, or failing component drawing excess current on that circuit. Continuing to replace the fuse without finding the cause risks wiring damage or a fire hazard, so at that point a proper diagnosis, including scanning for stored fault codes, is the right next step rather than fitting another fuse.
