- Remove the screwdriver and adjustable Torx insert from the vehicle tool adapter.
- Remove the footrest or appropriate cover.
- If necessary, remove the colored plastic clip from the fuse holder. The plastic clip can then be discarded.
- Remove the clamp from the back of the cover.
- Remove the fuse using pliers.
- A blown fuse should only be replaced with a new one of the same amperage.
- Replace the footrest or cover.
