The fuse for the factory Rear Entertainment System (RES) on a 2018 Honda Odyssey is usually a 15-amp fuse located in the interior fuse box on the driver’s side under the dash, labeled REAR ENT or DVD. If your model doesn’t show that label, consult the fuse diagram on the box cover or the owner’s manual for the exact position.
Inside the vehicle: locating the fuse
The interior fuse box is mounted under the dash on the driver's side. The lid's diagram identifies each fuse's function, including the rear entertainment circuit.
- Park the vehicle, turn off the engine, and remove the ignition key before opening the fuse box.
- Open the driver-side dash fuse box and locate the fuse labeled REAR ENT, REAR DVD, or something similar.
- Check the fuse's condition with a fuse puller; a blown fuse shows a broken metal strip inside.
- Replace a blown 15-amp fuse with a fuse of the same rating and recheck the system.
- If the fuse continues to blow after replacement, there may be a short or faulty component in the RES wiring or module.
If the fuse is blown, replacing it often resolves the problem temporarily, but repeated blows indicate an underlying issue that requires diagnosis.
Reading the diagram and labeling tips
Not all boxes use the same labeling. If REAR ENT or DVD isn’t visible, look for labels like "REAR ELECTR" or a circuit name that references the rear entertainment system.
Consult the owner’s manual or the fuse box cover for the exact fuse number and amperage specific to your vehicle’s trim and market.
Rear-area considerations: is there a second fuse box?
Some Odyssey trims or regional configurations may include a secondary fuse block in the rear cargo area that powers the rear entertainment system or related accessories.
- Check for a secondary fuse panel behind a panel in the rear cargo area, near the side wall or under the floor mat.
- If present, identify the fuse for the rear entertainment system using the rear panel’s diagram or the vehicle’s manual.
If a second fuse exists, it may be labeled differently depending on the market, but it will serve the same purpose: protecting the RES wiring and components.
What to do if you can't find a second fuse box
In some regions or trims, the RES may be powered exclusively through the interior fuse box. If you cannot locate a secondary fuse block, rely on the interior box and refer to the owner's manual for guidance.
Safety and maintenance
Always turn off the vehicle and disconnect power before inspecting or replacing fuses. If the fuse blows repeatedly, have a qualified technician inspect the rear entertainment system, wiring harnesses, and the RES unit for shorts or faults.
Summary
For the 2018 Honda Odyssey with a factory Rear Entertainment System, start by inspecting a 15-amp fuse in the interior driver-side fuse box labeled REAR ENT or DVD. If the fuse is intact but the system still malfunctions, seek professional diagnosis to rule out wiring faults or a failing RES unit. Always refer to your specific manual since fuse locations can vary by trim and market.
