How to Read the System Circuit Diagram

The circuit diagram of each system shows the electric circuit from the main fuse , fuse box or the ignition switch (at the top in the diagram) to the ground (at the bottom) so that the circuit can be followed easily when performing inspection and service work. For utilization of this diagram together with Connector Layout Diagram or List of Connectors (shape of connector/pin arrangement), refer to item "INDICATION OF CONNECTORS AND HOW TO READ THEM" in "HOW TO USE THIS SECTION".
