COMPOSITION AND CONTENTS OF WIRING DIAGRAMS


In each section, all specifications are listed, including optional specifications. Accordingly, some specifications may not be applicable for individual vehicles.
Section
Basic contents
Component locations
Locations are shown for each point of relays, ECUs, sensors, solenoid valves, inspection connectors, fusible links, fuses, etc. In the part’s lists, parts are listed in alphabetical order.
Configuration diagrams
Connector locations and harness wiring configurations on actual vehicles are illustrated. Especially, high-voltage wires (330 V) are described separately from low-voltage wires (12 V).
Circuit diagrams
Circuits from power source to earth are shown completely, classified according to system. There is a main division into power source circuits and circuits classified by system.

  • Junction block
    The entire circuit for the junction block is described, because only the part of the junction block needed is normally shown in each circuit diagram.
  • Joint connectors
    The internal circuits for all joint connectors are described, because only the part needed is shown in each circuit diagram.
  • Power source circuits
    Low-voltage power source circuits (12 V) from auxiliary battery to fusible links, fuses and the electric motor switch are described. High-voltage power source circuits (330 V) are described in high-voltage power source control circuits of circuits classified by system.
  • Circuits classified by system
    For each system, the circuits are shown from fuse to earth, excluding the power source sections.
