PRESENTATION OF THE DIAGRAMS
1. CIRCUIT DIAGRAM
a) Special feature
: The various circuits are presented in a functional way. therefore, where a unit is connected
to several circuits, its various sections are shown in (( exploded ~‘form on different vertical grid lines.
b) Method of identification
: Identification marks are divided into three sections :
- figures which identify components ( and not leads )
- letters LG. TB. AR etc... identifying wiring harnesses
_
other letters ( Bc. F, Gr, FN, Bl . . . ) identifying the colour of the extremity of the insulating sleeve.
NOTE
For the Iast group of identification marks, four cases may occur

.lMPORTANT
Identification marks for components and wiring harnesses are arbitrary
they have been
chosen for the sole purpose of facilitating the use of the diagrams.

2. WIRING DIAGRAM
This is a schematic diagram of the components as they are fitted on the vehicle.
It indicates the layout of the leads, and the approximate location of the components.
The method of identification is the same as for the circuit diagram.
