2022 Toyota RAV4 Fuse Box Diagram & Amperage

Quick answer

The 2022 Toyota RAV4 features three main fuse box locations: one under the hood, a second in the dashboard kick panel (driver's side), and a third in the cargo area (driver's side).

Under-Hood Fuse Box

This fuse box, located in the engine bay, primarily houses fuses and relays for high-current circuits such as the engine control module (ECM), fuel pump, headlights, and cooling fan. It's usually found near the battery.

Relay Locations (Under-Hood):

• EFI Relay: Controls power to the EFI system, including the fuel pump.
• MG CLT Relay: Controls the A/C magnetic clutch.
• C/FAN Relay: Controls the cooling fan.
• HORN Relay: Controls the horn.
• H-LP LH/RH Hi/Lo Relays: Control the headlight high and low beams.
• STARTER Relay: Controls the starter motor.

Dashboard Fuse Box (Driver's Side Kick Panel)

Located behind a panel on the driver's side, typically near the left footwell. This box manages fuses for cabin accessories, power windows, radio, and other interior electrical components.

Cargo Area Fuse Box (Driver's Side)

This fuse box is typically found behind a removable panel in the driver's side cargo area or trunk. It often contains fuses for rear accessories, power outlets, and trailer wiring (if equipped).

Note on Trim Variations: While this guide covers the most common fuse configurations for the 2022 Toyota RAV4, specific fuse assignments and amperage ratings can vary slightly between different trim levels (e.g., LE, XLE, XSE, Limited, Adventure, TRD Off-Road, Hybrid models) and optional equipment. Always consult the fuse box diagram printed on the inside of your fuse box lid and your owner's manual for the most accurate information pertaining to your specific vehicle.

How to test a fuse

Testing a fuse is a straightforward process:

1. Locate the fuse: Identify the suspected fuse using the diagrams above and the legend on your fuse box lid.
2. Visually inspect: Many fuses have a clear plastic body. Look for a broken wire or melted metal strip inside. If it's broken, the fuse is blown.
3. Use a fuse tester or multimeter: For a more reliable test, use a fuse tester or set a multimeter to the continuity setting.
   • With a fuse tester: Touch the tester probes to the two small metal test points on the top of the fuse. If the light on the tester illuminates, the fuse is good. If not, it's blown.
   • With a multimeter: Remove the fuse from its slot. Touch one probe to each metal blade of the fuse. If the multimeter beeps or shows a reading close to zero ohms, the fuse is good. If it shows "OL" (open loop) or no reading, the fuse is blown.
4. Replace with the correct rating: If a fuse is blown, replace it with a new fuse of the exact same amperage rating and type. Using a fuse with a higher rating can lead to serious electrical damage or fire.

Common blown fuses on this vehicle

While any fuse can blow, some are more commonly encountered due to various reasons:

• CIG/P/OUTLET (Cigarette Lighter/12V Outlets): These fuses are often blown due to overcurrent from charging multiple devices, using high-power accessories, or inserting a faulty charger. If your phone charger or air compressor stops working, check these first.
• RADIO/ACC (Radio/Accessory): Issues with aftermarket radio installations, short circuits in accessories, or even a faulty head unit can cause these to blow. If your infotainment system goes dark, start here.
• STOP (Brake Lights): A short in the brake light wiring or a faulty brake light switch can sometimes cause this fuse to blow. If your brake lights aren't working, this is a prime suspect.
• HTR/BLOWER (Heater Blower Motor): A failing blower motor, a short in the blower motor resistor pack, or a clogged cabin air filter putting strain on the motor can lead to this fuse blowing. If your cabin fan stops working, investigate this fuse.
• H-LP (Headlights): While less common with modern LED systems, a short in the headlight circuit or a faulty bulb (in halogen setups) could blow a headlight fuse. Always check both the specific side's fuse and any main headlight relays.
• EFI (ECM/Fuel Pump): If your RAV4 cranks but doesn't start, or you experience significant engine performance issues, this fuse is critical as it powers the engine control unit and fuel pump. If this fuse blows, it often indicates a more serious underlying issue that needs professional diagnosis.

What to check first: When you experience an electrical issue, always start by identifying which circuit is affected. Then, locate the corresponding fuse and visually inspect it. If it's clearly blown, replace it. If the new fuse blows immediately, do not keep replacing it – there's likely a short circuit or a component fault that needs professional attention.
