In each section, all specifications are listed, including optional specifications. Accordingly, somespecifications may not be applicable for individual vehicles.

Section Basic contentsSingle partinstallation position

Locations are shown for each point of relays, electronic control units, sensors,solenoids, solenoid valves, diodes, inspection connectors, spare connectors, fusilinks, fuses, etc. In the part’s lists, parts are listed in alphabetical order.

Wiring harnessconfigurationdiagrams

Connector locations and harness wiring configurations on actual vehicles areillustrated.

Circuit diagrams Circuits from power supply to earth are shown completely, classified according tosystem. There is a main division into power circuits and circuits classified by systeThe circuits classified by system also include operation and troubleshooting hints

• Junction blockThe entire circuit for the junction block is described, because only the part of th junction block needed is normally shown in each circuit diagram.

• Joint connectorsThe internal circuits for all joint connectors are described, because only the paneeded is shown in each circuit diagram.

• Power supply circuitsCircuits from the battery to fusible link, fuses, ignition switch, etc.

• Circuits classified by systemFor each system, the circuits are shown from fuse to earth, excluding the powesupply sections.

• OperationThe standard operation of each system is briefly described, following the routecurrent flow.

• Troubleshooting hintsThis is a brief explanation of the inspection points that serve as hints whentroubleshooting. Explanations of the circuits controlled by the electronic controunit are omitted. Refer to the related publications as required.

WIRE COLOR CODEM1001008000054

Wire colours are identified by the following colourcodes.

If a cable has two colours, the first of the two colourcode characters indicates the basic colour (colour ofthe cable coating) and the second indicates themarking colour.

NOTE:

*: No code indicates 0.5 mm 2 (0.0008 in 2 ). Cable

colour code in parentheses indicates 0.3 mm 2

(0.0005 in 2 ).
