This procedure covers removal and replacement of the interior fuse box assembly on 2018-2024 Honda Accord 1.5L Turbo models, including disconnection of electrical connectors and mounting hardware.

Warnings

Tools required

Parts

• Interior fuse box assembly × 1 — Use OEM specification
• Fuse box cover trim clips (if damaged) × 4 — Honda OEM clips

Preparation

1. Park vehicle on level ground and set parking brake
2. Turn ignition to OFF position and remove key fob from vehicle interior
3. Open driver's door and lower driver's window completely
4. Photograph or document current fuse positions for reference
5. Disconnect negative battery terminal and secure cable away from battery post
6. Wait minimum 3 minutes for airbag system discharge

Procedure

1. 1

   Remove lower dashboard panel
   Locate the lower dashboard trim panel below the steering column on the driver's side. Remove two Phillips screws at the bottom edge. Carefully pull the panel away from the dashboard, releasing the retaining clips. Disconnect the OBD-II port connector if equipped with one integrated into the panel. Set panel aside.
2. 2

   Remove fuse box cover
   Open the interior fuse box cover located on the driver's side lower dash panel. The cover is typically held by plastic tabs. Gently pull the cover away from the fuse box to release the clips. If the cover has screws, remove them first using appropriate driver.
3. 3

   Document and remove fuses
   Take a clear photograph of all installed fuses and their positions. Using a fuse puller or needle-nose pliers, carefully remove all fuses from the fuse box. Place them in a labeled container or tape them to paper matching their original positions. Note any blown fuses for replacement.
4. 4

   Disconnect main electrical connectors
   Locate the large multi-pin connectors on the back of the fuse box. There are typically 3-4 main connectors. Press the locking tab on each connector and carefully pull straight back to disconnect. Mark each connector with tape indicating its position (e.g., 'top left', 'bottom right') for reassembly reference.
   ⚠These connectors require significant force but should not be pried - ensure locking tabs are fully released before pulling
5. 5

   Disconnect ground strap
   Locate the ground strap attached to the fuse box mounting bracket, typically on the left side. Use a 10mm socket to remove the ground strap bolt. Keep the bolt and any washers together. Inspect the ground contact point and clean if corrosion is present.

6. 6

   Remove fuse box mounting bolts
   Locate the fuse box mounting bolts securing the assembly to the dashboard structure. There are typically two 10mm bolts accessible from the front or side of the fuse box. Remove both mounting bolts completely and retain them for reinstallation.
   ℹ️Support the fuse box with one hand while removing the final mounting bolt to prevent it from falling

7. 7

   Remove fuse box assembly
   With all connectors and mounting bolts removed, carefully maneuver the fuse box assembly out of its mounting location. You may need to tilt or rotate it slightly to clear surrounding dash components. Inspect the mounting area for any loose hardware or debris before installing the new unit.
8. 8

   Install new fuse box assembly
   Position the new fuse box assembly into the mounting location, orienting it to align with the mounting bolt holes. Ensure no wiring is pinched behind the unit. Thread both mounting bolts by hand first to ensure proper alignment before tightening.

9. 9

   Reconnect ground strap
   Attach the ground strap to the fuse box bracket. Ensure the contact surface is clean and free of paint or corrosion. Install the ground strap bolt with washer and tighten to specification. Verify the strap has solid metal-to-metal contact.
   ℹ️Clean ground connections are essential for proper electrical system operation

10. 10

    Reconnect electrical connectors
    Reconnect each of the main electrical connectors to the fuse box, referencing your earlier markings. Push each connector firmly until you hear or feel the locking tab click into place. Gently tug on each connector to verify it is fully seated and locked.
11. 11

    Reinstall fuses
    Using your photograph or documentation as reference, reinstall all fuses into their correct positions in the new fuse box. Ensure each fuse is fully seated in its holder. Replace any blown fuses with new fuses of the correct amperage rating as marked on the fuse box diagram.
    ⚠Never install a higher amperage fuse than specified - this can cause electrical fires or component damage
12. 12

    Reconnect battery and test
    Reconnect the negative battery terminal and tighten the terminal bolt to specification. Do not overtighten as this can damage the battery post. Turn the ignition to ON position (engine off) and verify the instrument cluster illuminates properly. Check that all interior lights, power windows, and accessories function correctly.

13. 13

    Reinstall trim panels
    Reinstall the fuse box cover, ensuring all clips engage properly. Reconnect the OBD-II port connector if applicable, then position the lower dashboard panel. Align the retaining clips and press firmly to seat them. Install the two lower panel screws and tighten securely but do not over-torque plastic mounting points.

Reassembly

1. Verify all electrical connectors are fully seated and locked
2. Ensure all fuses are installed in correct positions matching documentation
3. Confirm all dashboard trim panels are secure with no gaps or loose clips
4. Double-check battery terminal is tight and cable is properly routed

Verification

• Turn ignition to ON and verify all dashboard warning lights illuminate then extinguish normally
• Test all interior lighting including dome lights, map lights, and footwell lights
• Verify power windows operate in both directions and auto-up/down functions work (may require calibration)
• Test climate control system, radio, and all accessory power outlets
• Scan for diagnostic trouble codes using OBD-II scanner - there should be no new electrical system codes
• Verify turn signals, hazard lights, and exterior lighting function properly
• Test horn operation
• Start engine and confirm normal operation with no warning lights
