HOW TO READ CIRCUIT DIAGRAMS CIRCUIT DIAGRAMS 90-4 36DB002A Indicates representative vehicle body ground point. (Same number as that of ground point in GROUNDING LOCATION). Indicates harness junction where wire diameter or color changes. In case two or more connectors are connected to the same de- vice, markings indicating the same connector is connected by a broken line. Indicates terminal number. Indicates intersections at which the lead wires are not connected. Indicates intersections at which the lead wires are connected. Indicates input/output to/from control unit (current flow direction). Input Output Input/ output
Indicates that the diagram comes from which belongs to the block in the same circuit. Indicates a wiring connector which is inside the equipment and which is not shown in the wiring harness configuration diagram. Example C-15-2 Indicates a connector which is inside the equipment, numbered in order starting from 1. Indicates the connector number shown in the wiring harness configuration diagram. Bi-directional arrow indicates that current flows in both direc- tions due to control by an ECU. Indicates that the terminal is a spare one if the device (sensor in this case) is not provided. |
