2022 Land Rover Discovery Fuses
FUSE BOX LOCATIONS
CAUTION
When a fuse box lid is removed, take care to protect the box from moisture. Refit the lid at the earliest opportunity.
Access can be gained to the fuses, as follows:
- Loadspace fuse box: Turn the catch 90° counter-clockwise and remove the rear access panel.
- Slide the top catch rearward.
- Grasp the top of the forward access panel, and remove it by pulling sharply.
When refitting the access panel, make sure the securing pegs are aligned with the respective holes before pushing the panel fully home. The refit procedure is the reverse of the removal procedure.
- A label, located to the side of the fuse box, shows the circuits protected and the fuse locations.
- Passenger compartment fuse box: Open the glovebox. See STORAGE COMPARTMENTS. Firmly press the top of the support stay at each end and lower the glovebox into the footwell. A label on the front of the fuse access panel shows the circuits protected and the fuse locations. Remove the panel to gain access to the fuses.
- Engine compartment fuse box: Remove the under-hood cover. See UNDER-HOOD COVERS REMOVAL.
- Lift up the edge of the leaf screen panel just enough to allow removal of the fuse box cover.
- Remove the fuse box cover, by releasing the clips on
REPLACING A FUSE
CAUTION
Always switch off the ignition system and the affected electrical circuit before replacing a fuse. Failure to do so could cause damage to the vehicle.
CAUTION
Fit-approved replacement fuses of the same rating and type or fuses of a matching specification. Using an incorrect fuse may result in damage to the vehicle’s electrical system and can result in a fire.
CAUTION
If the replacement fuse blows after fitment, the system should be checked by a retailer/authorized repairer. Further damage could be caused to the vehicle if ignored.
NOTES
Relays and fuses not detailed in the Owner’s Handbook should only be replaced by qualified persons.
If an electrical system has stopped operating, the cause may be a blown fuse. The easiest way to check if a fuse has blown is to first remove it.
To check for a blown fuse:
- Refer to the fuse box tables shown in this section to identify the correct fuse.
- Gain access to the appropriate fuse box. See FUSE BOX LOCATIONS.
- Refer to the fuse box label to locate the correct fuse. Depending on the fuse box, the label is located on the underside of the lid.
- Use the fuse removal tool to remove the fuse. See FUSE BOX LOCATIONS.
- Check for a break in the wire within the fuse. If the wire within the fuse is broken, the fuse has blown and needs replacing. If the wire is still intact, consult a retailer/authorized repairer.
- Refit or replace the fuse, as appropriate. Make sure the fuse is pushed fully into its correct position.
