2015 Toyota Tacoma Fuse Box Diagram & Amperage

Quick Answer

The 2015 Toyota Tacoma typically has two main fuse box locations: one under the hood (Engine Compartment) and another in the cabin (Driver's Side Kick Panel). Some models or trims might have additional relays or circuit breakers for specific accessories, but these are the primary locations.

Under-Hood Fuse Box (Engine Compartment)

The under-hood fuse box on your 2015 Toyota Tacoma is located in the engine bay, usually on the driver's side, near the battery. This box contains fuses for critical engine components, headlights, and other high-current systems. Always consult the diagram on the fuse box lid for the most accurate information for your specific vehicle configuration.

Interior Fuse Box (Driver's Side Kick Panel)

The interior fuse box for your 2015 Toyota Tacoma is located inside the cabin, typically on the driver's side, behind a small panel or door in the kick panel area (near your left foot when seated). This box handles fuses for accessories, interior lights, power windows, and other cabin functions. Always refer to the diagram on the fuse box cover for your exact vehicle.

How to Test a Fuse

Testing a fuse is a straightforward process that can help diagnose electrical issues. Here's how you can do it:

1. Safety First: Ensure the vehicle's ignition is off and disconnect the negative terminal of the battery if you're working on critical circuits.
2. Locate the Fuse Box: Identify the fuse box relevant to the circuit you're troubleshooting.
3. Identify the Fuse: Consult the fuse box diagram (usually on the lid or in your owner's manual) to find the fuse for the suspected circuit.
4. Remove the Fuse: Use a fuse puller (often found in the fuse box) or small needle-nose pliers to carefully remove the fuse.
5. Visual Inspection: Hold the fuse up to the light. If the metal wire or strip inside is broken or burnt, the fuse is blown and needs replacement.
6. Use a Multimeter (for a more accurate test):
   • Set your multimeter to the continuity setting (usually indicated by an audible beep or a diode symbol).
   • Touch the probes to the two metal test points on top of the fuse (or the metal ends if it's a blade fuse). A good fuse will show continuity (a beep or a reading close to zero ohms). If there's no continuity, the fuse is blown.
7. Replace (if necessary): If the fuse is blown, replace it with a new fuse of the exact same amperage rating and type. Never use a fuse with a higher amperage rating, as this can lead to serious electrical damage or fire.

Common Blown Fuses on This Vehicle

While any fuse can blow, some circuits tend to see more activity or higher loads, making their fuses more prone to blowing. For the 2015 Toyota Tacoma, common culprits for blown fuses often include:

• Cigar Lighter / 12V Power Outlets (CIG / PWR OUTLET): These fuses often blow due to overloading from charging multiple devices or using high-power accessories. If your phone charger or other accessories stop working, check these fuses first.
• Radio / Infotainment System (RADIO): Issues with aftermarket installations, short circuits in wiring, or even internal issues with the unit itself can cause this fuse to blow if your radio goes dark.
• Blower Motor (HTR / A/C BLWR): The blower motor can draw significant current, especially on higher fan settings. If your A/C or heater fan stops working, this fuse is a prime suspect.
• Headlights (H-LP LH/RH LO/HI): While less common, a faulty bulb or a short in the headlight wiring can sometimes cause a headlight fuse to blow. If one or both headlights are out, check the respective fuses.
• Trailer Brake (TOWING BRK, if equipped): Issues with trailer wiring or a short in the trailer's electrical system can frequently cause this fuse to blow if you experience problems with trailer brakes.

What to check first: Before checking fuses, verify the obvious. For headlights, check the bulbs. For power outlets, remove the devices as a test. If you've recently installed an aftermarket accessory, double-check its wiring.
