The first-generation Toyota Tundra (Model Codes: XK30/XK40 ), in its Regular Cab and Access Cab configurations, was produced from 2000 to 2006 . As Toyota’s inaugural full-size pickup truck for the North American market, the Tundra combined Toyota’s signature reliability with the power and utility needed for work and recreation. It featured a range of engine options, including a V6 and a V8, and offered solid towing and hauling capabilities.
In this article, you will find fuse box diagrams for the Toyota Tundra , covering model years 2000, 2001, 2002, 2003, 2004, 2005, and 2006 . These diagrams are an essential resource for identifying the location and function of each fuse and relay in the vehicle.
What’s Included:
Fuse Box Diagrams – Clear, labeled layouts to help you identify each fuse and relay quickly and accurately.Fuse Panel Locations – Easy-to-follow directions to locate the fuse panels inside the cabin and engine compartment.Fuse Assignments – Descriptions of fuse functions for key vehicle systems such as lighting, wipers, ignition, power accessories, and more.
Whether you’re tracking down a blown fuse or resolving an electrical fault, this guide provides the information needed to keep your Toyota Tundra (2000–2006) running smoothly and reliably.
The fuse box is located in the driver’s side of the instrument panel, behind the cover.
It is located in the engine compartment (left-side).
