Fuse box diagram (fuse layout), location, and assignment of fuses and relays Toyota Tacoma (Regular cab, Xtra cab, and Double cab) (2001, 2002, 2003, 2004).
Checking and Replacing Fuses
The fuses are designed to blow before the entire wiring harness is damaged. If any of the electrical components do not operate, a fuse may have blown. If this happens, check and replace the fuses as necessary.
- Turn the engine switch off and turn off all electrical accessories.
- Open the fuse box cover.
- See diagrams below for details about which fuse to check.
- Remove the fuse.
- Check if the fuse is blown – if the thin wire inside is broken, the fuse has blown.
- Replace the blown fuse with a new fuse of an appropriate amperage rating.
Notice
- Never use a fuse of a higher amperage rating than that indicated, or use any other object in place of a fuse, even as a temporary fix. This can cause extensive damage or even fire.
- Always use a genuine Toyota fuse or equivalent.
- Do not modify the fuses or fuse boxes.
- If the replaced fuse blows again, have the vehicle inspected by any authorized Toyota dealer or repairer, or another duly qualified and equipped professional.
