Explanations

In each diagram, the complete system (e.g. ETS) is shown, including all related parts from grounding points up to the wiring connector or circuit fuse. Unrelated components and wires are not shown.

Options/Variations
Each wiring diagram may also contain information about variations in the circuit due to optional equipment or vehicle model differences, clearly labeled in a dashed box. These variants may be labeled with a "U--" designation, a system abbreviation, or a chassis number/production date range. The meaning of the "U--" designation is found in the component name listing, while the meaning of the abbreviation or chassis number/production date range is self-explanatory. If an unfamiliar abbreviation is encountered refer to "Acronyms Used".

Component Designations





Components are designated in the familiar fashion, e.g. K40. If reference to a particular connection is necessary, it is shown in the format "K40 (1.2)", meaning relay module K40, connector 1, pin 2. Component names are no longer included on the wiring diagram itself, but shown in a separate image beneath the diagram.

Fuse Box Representation
Each fuse has up to five possible connection points, designated by the letters A through E. Terminal E is always the supply or entry side. Fuses with only one output terminal always have their output (fused side) at terminal D. Fuses with more than one output terminal will always have their output on terminals A, B and/or C, and never terminal D. This is because a special bridge is installed at terminal D whenever additional outputs are needed, making it unavailable for a wire connection.

The terminal letter is always written next to the wire whenever a fuse box is shown in the wiring diagram. Terminals may also be designated with their fuse number and terminal letter, e.g. 17E is terminal E on fuse 17.

Inside the fuse, the amperage rating of the fuse is shown. Directly next to the fuse, the fuse box number designation is shown. Near the wiring entry or exit point, the circuit designation is shown.

Circuit Designations
Within various components, a numerical or alphabetical circuit designation may be shown. These are provided to help determine the function of a particular circuit. For example, circuit 30 is unswitched power from the battery, and circuit 15 is switched power via the ignition switch. A complete listing of all circuit designations used in the wiring diagrams for this model can be found in "Acronyms Used".

Wiring Designations





Each wire carries a designation showing its cross-sectional area (in square millimeters) and its color. If a wire must be replaced, always use the same or larger wiring size to prevent overheating. Approximate conversion between cross-sectional area and American Wire Gauge (AWG) is as shown in image.
