Electrical panel locations in cabin and engine bay with access instructions
Open the driver-side lower dash trim and remove the small rectangular cover to reach the interior power distribution panel; use a plastic pry tool to release two clips without cracking the panel, then pull it straight out.
Inside the cabin section, the block sits slightly above the footwell, aligned left of the steering column. Use a flashlight to read the printed layout on the inner side of the cover; low-profile mini blade elements are arranged in vertical rows, with amperage values stamped on top. Grip the provided puller tool clipped near the edge to remove any unit safely.
For the engine compartment unit, lift the hood and locate the sealed black housing near the battery on the right side. Press both side latches firmly and lift the lid upward; do not force it at an angle to avoid breaking hinges.
This under-hood module contains high-current links and relays for cooling fans, ABS pump, and ignition circuits. Larger cartridge-style protectors are fixed with bolts; use a 10 mm socket to remove them instead of pulling by hand.
Before accessing either location, switch off ignition and disconnect the negative battery terminal when working with high-amperage circuits. This prevents accidental shorting while handling exposed contacts.
If access feels restricted in the cabin, slide the driver seat fully back and tilt the steering wheel upward to gain more space for your hands and tools.
After completing checks or replacements, reinstall covers by aligning tabs first, then pressing until all clips click into place; a loose cover can cause rattling and expose components to dust.
Verify operation of affected systems immediately after reassembly to confirm that the correct circuit element was serviced and seated properly.
2017 Honda CRV fuse diagram and circuit identification guide
Check the legend printed on the inner cover first and match each slot number to its circuit to avoid pulling the wrong protective element; for this model, interior panel positions F19–F22 typically control accessories like audio unit, power outlet, and display module, while F27–F30 relate to door locks and window motors.
Use the following mapping approach to identify circuits accurately:
- Locate the slot index stamped near each terminal
- Compare it with the cover legend or service manual table
- Confirm amperage rating such as 7.5A, 10A, 15A before removal
- Trace the related system: lighting, HVAC, infotainment, or control modules
Engine compartment distribution panel contains higher load links:
- 30A–40A units for radiator fan and ABS pump
- 50A main supply feeding cabin circuits
- Relay blocks controlling ignition and fuel system
Use a multimeter to verify continuity instead of visual inspection only; a blown strip may look intact but fail under load. Always reinstall components in the exact slot and orientation to prevent misrouting current across unrelated systems.
Fuse box locations in cabin and engine bay with access instructions
Remove the driver-side lower trim panel to access the interior electrical distribution unit; insert a flat plastic tool into the side notch, twist gently to release clips, and pull the cover straight outward without bending it.
The cabin-mounted panel sits to the left of the steering column, slightly above the footwell. Mini blade components are arranged in compact rows, and the puller tool is usually clipped inside the cover. For better reach, slide the seat back fully and tilt the steering wheel upward to create working space.
Open the hood and locate the engine compartment power center near the battery; press both locking tabs and lift the lid evenly. Inside, larger cartridge-style elements and relay modules control high-load systems such as cooling fans, ignition supply, and braking electronics. Use a socket wrench for bolted links instead of pulling them by hand.
Disconnect the negative battery terminal before touching high-current sections, then reinstall covers by aligning tabs first and pressing until each clip locks; a loose lid allows moisture and debris to reach contacts.
