Definition of Vehicle Component Codes

All components are identified by a letter followed by an arbitrary number assigned to the component. The letter assigned to the component indicates the type of component.

Bulbs, Heated Screens, Mirror Demisters, Cigar Lighters, and Heated Washer Jets

Relays, Solenoids, Speakers, and Resistors

Motors

Fuse Boxes and Fusible Links

Switches and Sensors

Zz Electronic Control Units, Modules, Shields, Diodes, and Capacitors

Wire Colours

All wires are identified by letters which indicate a certain colour. Wire colour and size will only be shown once if it does not change throughout the circuit. The following chart explains the wire colour abbreviations.

B - Black P - Purple G - Green R - Red K - Pink S - Grey L - Light U - Blue N - Brown W - White O - Orange Y - Yellow

Previous and Next Arrows

Schematic pages which follow another schematic page of the same chapter will have an arrow in the upper left hand corner. There is no arrow on the first schematic page of a chapter. Schematic pages which are followed by another schematic page will have an arrow in the lower right hand corner. If the page is the last page of the chapter, there will be a square instead of an arrow.

Page Qualifiers

Schematic pages which are specific to certain model, option or country variations will have a small “Qualifier” after the Previous Arrow in the upper left hand corner. For example, a section might contain pages specific to petrol engines and some pages specific to diesel engines. “Petrol” will be shown in the upper left hand corner of petrol specific pages, and “Diesel” will be shown in the upper left hand corner of diesel specific pages.
