System Circuit Diagram

System Circuit Diagrams consist of Power Supply Circuit Diagrams, Earth Point Circuit Diagrams, and System Circuit Diagrams. Circuit diagrams can be used to check the positions of connectors, wiring harnesses, fuses, relays, etc., and the wiring of systems.

Display Connectors and Other Details from System Circuit Diagrams

	Select the part or wire and click on the Connectors and Other Details. Connectors and Other Details are displayed for the selected part or for parts connected to the wire.

Execute Compact Display

In Compact Display, select multiple wires or parts and switch to a condensed display that only includes the connections between those wires.

	Select parts or wires in the System Circuit Diagram and click on the Compact Display button. Wires are displayed flashing, and parts are displayed flashing (in red). If a wire is selected, the parts at the two ends of that wire flash alternately. HINT Internet Explorer versions 6.0/8.0 do not support Compact Display.

Fuse list

The fuse list can be used to check the names and capacities of fuses. It can also be used to check which systems are supplied with power by which power supplies.
