Introduction

Schematics were not edited for the U.S. market. They may contain information applicable worldwide.

The 163 Chassis schematics are organized in a similar fashion to the passenger car schematics.

How To Use Schematics
This article describes how the schematics are organized. It also explains what kind of information ALLDATA contains, what that information means, and how to use it to troubleshoot electrical problems.

Circuit schematics break the entire electrical system into individual systems, like the Sunroof in the image below. Only electrical components that work together are shown together, so you won't be distracted by unrelated wires.

Explanations of the abbreviations and symbols used in the schematics can be found at "Symbols". You'll need to know what they mean before you can use a schematic effectively. Symbols/Color Codes


Circuit Schematics





Each schematic represents one circuit. A circuit's wires and components are arranged to show current flow, from power at the top of the page, to ground, at the bottom.

Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves.

If that component works, you know the shared wiring is OK.

All connectors are labeled (P/C, X18/2, etc.). When there are more than one connector to a component, the connectors are labeled sequentially, such as C1, C2, or P/B, P/C, etc. For more information see the Component Location Index.

Connector cavities are also labeled (F, 2, etc.).

Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The letter "F" next to the male and female wire terminals at X18/2, for example, means those terminals join in cavity F of connector X18/2.

Power Distribution Schematics
Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the car. Refer to the Power Distribution section to get a more detailed picture of how power is supplied to the circuit you're working on. Electrical Diagrams


From Battery to Ignition Switch, Fuses, and Relays





Individual circuit schematics begin with a fuse.


Ground Distribution Schematics





This sample Ground Distribution schematic shows all of the components that share three ground points.


Component Locations
There are two component location charts provided in Component Locations and the Connector Views sections. The first is sorted alpha-numerically by component name. The second is sorted alpha-numerically by the component designation number. Each chart shows the figure reference where a photo, connector view, splice location or schematic location can be found. For your convenience we have placed hyperlinks in the component location charts which will take you directly to the section which contains the figures.
