Quick Answer
The 2025 Toyota Tacoma features multiple fuse box locations to protect its various electrical systems. You'll find fuse boxes primarily in two main locations: under the hood and inside the cabin on the driver's side kick panel. There is no fuse box located in the trunk or cargo area for this model year.
Under-Hood Fuse Box
The under-hood fuse box, usually located near the battery, primarily houses fuses and relays for high-current circuits such as the engine control module (ECM), fuel pump, headlights, ABS, and other critical powertrain components. Always refer to the diagram on the fuse box lid for the most accurate information on your specific trim.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| EFI | 20A | Yellow | EFI Main Relay, ECM |
| FUEL P | 15A | Blue | Fuel Pump |
| IGN | 15A | Blue | Ignition System |
| STR | 25A | Clear | Starter Relay |
| H-LP RH | 10A | Red | Right Headlight (Low Beam) |
| H-LP LH | 10A | Red | Left Headlight (Low Beam) |
| H-LP HI | 10A | Red | Headlights (High Beam) |
| TAIL | 10A | Red | Tail Lights, Parking Lights |
| STOP | 10A | Red | Brake Lights |
| ABS NO.1 | 30A | Green | ABS Motor |
| ABS NO.2 | 15A | Blue | ABS Solenoids |
| A/C MGT | 10A | Red | A/C Clutch Relay Circuit |
| TOWING | 30A | Green | Trailer Brake Controller (Accessory) |
Relays in Under-Hood Fuse Box: Look for labeled relays for components like the EFI Main Relay, Fuel Pump Relay, Starter Relay, Headlight Relays (Low/High Beam), and A/C Clutch Relay. Their exact positions will be indicated on the fuse box lid diagram.
Cabin Fuse Box (Driver's Side Kick Panel)
The cabin fuse box, typically located behind a panel on the driver's side kick panel, protects a variety of interior electrical components like the blower motor, radio, power outlets, and other convenience features. Again, always consult your owner's manual or the fuse box lid for precise designations for your vehicle's trim and options.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| CIG | 15A | Blue | Cigar Lighter / 12V Power Outlet |
| PWR OUT | 20A | Yellow | Additional 12V Power Outlets |
| RADIO | 10A | Red | Radio / Infotainment System |
| HEATER | 40A | Green | Blower Motor (Main) |
| FAN | 10A | Red | Blower Motor Control |
| DOOR | 10A | Red | Door Locks |
| ACC | 10A | Red | Accessory Power (Radio, Wipers) |
| GAUGE | 10A | Red | Instrument Cluster, Gauges |
| SRS | 10A | Red | Airbag System (Supplemental Restraint System) |
| WIPER | 20A | Yellow | Windshield Wipers |
Relays in Cabin Fuse Box: The cabin fuse box may contain relays for accessories like power windows, door locks, or the accessory power circuit. Refer to the fuse box diagram for specific relay locations.
How to Test a Fuse
Testing a fuse is a straightforward process that can help diagnose electrical issues. Here's how:
- Locate the Fuse Box: Identify the fuse box related to the malfunctioning component.
- Identify the Suspect Fuse: Consult the fuse box diagram to find the fuse for the circuit you're troubleshooting.
- Visual Inspection: Most modern fuses are transparent, allowing for a quick visual check. A blown fuse will have a broken wire or melted metal strip inside. If it's dark or opaque, you'll need a multimeter.
- Use a Multimeter:
- Turn off the ignition and remove the fuse using a fuse puller (often found in the fuse box lid).
- Set your multimeter to the continuity setting (usually indicated by a sound wave or diode symbol).
- Touch one probe of the multimeter to each metal terminal on the fuse.
- If the multimeter beeps or shows a reading of zero ohms (or very close to it), the fuse is good. If there
Before you pull a fuse on the 2025 Toyota Tacoma
- Use the label printed on the panel cover or the owner's manual for your exact build. Layouts change with options, model year and build date, so a chart for another truck can be wrong.
- Replace a blown fuse only with the same amp rating. A larger fuse can let wiring overheat.
- A fuse that blows again right away means a short or failing component downstream. Find the cause before replacing it again.
- A good fuse doesn't prove the circuit works — relays, grounds and connectors fail too.
- Disconnect the battery before working near high-current fuses or cables.
