How to Use Wiring Diagrams

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair DaimlerChrysler Corporation vehicles, it is important to understand all of their features and characteristics.

Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition (Fig. 2).

Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around the component indicates that the component is being shown is not complete. Incomplete components have a reference number to indicate the sheet where the component is shown complete. To find any diagram sheets referred to by number only, go to Vehicle/Diagrams/Electrical/Diagrams By Number.

It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only.

The wiring diagrams are grouped into individual sets at the applicable system level. If a component is most likely found in a particular system, it will be shown complete (all wires, connectors, and pins) within that system's diagrams. It can, however, be shown partially in another system's diagrams if it contains some associated wiring.

SYMBOLS

Fig.3 Wiring Diagram Symbols:

International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world (Fig. 3).


CIRCUIT FUNCTIONS

Circuit Identification Code Chart:

All circuits in the diagrams use an alpha/numeric code to identify the wire and it's function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models.


CIRCUIT INFORMATION

Wire Color Code Chart:

Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gage of wire, and color (Fig. 4).
