Symbols Used In the Wiring Diagrams

The wiring diagrams are drawn using the following conditions:
^ Unless otherwise indicated, switches and relays are represented in their inactivated and unenergized state.
^ No key in the ignition switch
^ Central locking system unlocked
^ Coolant, brake and washer fluid topped up
^ Gear lever/selector lever in neutral position
^ Switches in oft positions
^ Handbrake released





Fuses
In the wiring diagrams, every subsystem is generally shown from the relevant fuse in the main fuse box up to the respective component or components and on to the grounding point/direct chassis connection.

To simplify fault diagnosis, a broken line is used in certain instances to signify the power supply.

The power supply to each fuse is shown separately in the power supply wiring diagrams.

Example:
If the supply to a fuse comes from the +30 terminal, the circuit to the fuse in question will be found in the section headed "Power supply +30".





Grounding Points
Most of the car's grounding points have a component designation consisting of a letter and a number, e.g. G14. The locations of the grounding points are given in the section "Grounding points".

Certain components are grounded directly to the body, e.g. the door switches. These ground connections are indicated by a thicker line than normal connections to the grounding point.





Switches, Relays And Components
The location of the relays is given in brackets below the component number.
When the box round the component is drawn with a solid line, the whole component is shown.

When the box round the component is drawn with a broken line, only pant of the component is shown.

On some components having a hanging lead, the connector has not been given a separate H number to show that it is part of the component.

The components are designated by a serial number and one or more supplementary letters, which indicates their location and type. The location is indicated by capital letters, e.g. 298FL, while the type is indicated by lower case letters, e.g. 47a. The following abbreviations are used to indicate position:

C = Centre
D = Driver side
F = Front
H = Hatch (boot lid)
P = Passenger side
R = Rear
LH = Left-Hand
RH = Right-Hand





Sensors And Monitors
The symbols for sensors and monitors have been simplified. The connector/output side of the sensors have an internal symbol showing the type of output signal and the other half is a symbol showing the measured quantity.

All internal symbols for the measure quantity may be used with other components.
a Sensor output with continuous voltage
b Sensor output with pulse voltage, e.g. frequency or PWM

The outputs are combined with the following quantity symbols to indicate the correct type of sensor:
c Temperature
d Speed/r.p.m. via a toothed wheel or similar
e Level
f Sun
g Load
h Angle
i Acceleration
j Pressure

One type of sensor that can be used for different purposes is
k Hall sensor

A monitor is shown as a switch with measured quantity:
l Level switch
m Pressure switch





Crimped Connections
To reduce the number of connectors used in the car, several crimp connections are incorporated in the wiring.

The crimp connectors immediately above the grounding points have been ultrasonic welded for reliability.
