3. CODING OF FUNCTIONS:
The principle of this numbering is to attach the component number to an electrical function.
The functions are grouped in 8 families.
1. Power unit:
10 - starting, current generation
11 - ignition system, pre-heating
12-13 - fuel system, fuel injection
14 - engine diagnostics
15 - cooling system
16 - gearbox, drive shafts
17 - engine electrical supply - accumulator
2. Exterior lighting and signaling:
20 - rear fog lamps
21 - stop lamps
22 - reversing lamps
23 - direction indicator, side repeater flashers, hazard warnings
24 - running lights, headlamp dim-dip (DIM-DIPS)
25 - horns
26 - headlamps, tail lamps, number plate lamps, side lamps and indicator lamps
3. Interior lighting:
30 - passenger compartment lighting
31 - closed compartment lighting
4. Driver information:
40 - engine coolant and other water information, current generation
41 - engine oil information

8. Driving comfort:
80 - heating/ventilation, air conditioning
81 - heating equipment (heated rear screen, glass and mirrors, glass, lighter)
82 - coded anti-start
83 - heated seats
84 - radio, aerial, radio telephone
85 - ice warning
86 - anti-theft alarm system
87 - electrically controlled blind
4. COMPONENT CODING:
Components have a four figure number e. g.: 4310.
The first two figures indicate the function, the two following figures identify the component.
The numbers for indicator lamps are preceded by the letter V e. g.: V2610.
Special numbering of equipment which supplies an electrical feed:
BB10: battery + ve unit
CA00: ignition switch
BF00: fuse box
Free connectors which have a particular function (e. g. testing a function) are numbered as components with the letter С in front e. g.: C1300.
Numbering of earth points:
the letter M is used followed by an identifying number
examples: M2A, M90C
the letter E is used followed by an identifying number
examples: E028, E002
application of an alphabetical index if the splices are identical, e. g: E005A, E005B
5. INTERCONNECTION NUMBERING:
The letters IС are used followed by a 2-digit identifying number.
Application of an alphabetical index if the interconnections are identical, e. g: IC20, IC05A, IC05B.
6. NUMBERING OF BRIDGE BLOCK CONNECTORS:
The letter В is used, followed by a 3 figure number, e. g: B001.
Application of an alphabetical index if terminals are identical e. g: В00ЗА, В00ЗВ.
7. WIRE CODING:
This code enables linking of the wire number to the type of supply or the electrical function.
Supply is broken down as follows.
Supply before a fuse:
BB: battery + ve supply
AA: accessory + ve supply
CC: ignition controlled + ve supply
W: side lamp + ve supply
KK: + ve supply after ignition switched off
Example: BB2 (type of supply + wire identification number).
Supply after a fuse:
В: battery + ve supply
A: accessory+ ve supply
С: ignition controlled+ ve supply
V: side lamp+ ve supply
К:+ ve supply after ignition switched off
Example: B02A (type of supply+ fuse number+ wire identification number, figure or letter).
Example: M262 (type of supply+ wire identification number, figure or letter).
Comments: each vehicle has special features in the coding of the wires concerning the supplies
(they are handled as variants).
Other connections between components:
the figures on the left repeat the number of the function concerned (see: coding of functions)
the figures on the right represent the identification number in the function
Example: 2604 (function number+ wire identification number).
These abbreviations are quoted on the terminals of certain components (e. g ignition switch).
+ BB: battery + ve.
+ AA: accessory + ve.
+ CC: ignition controlled + ve.
+ KK: + ve after ignition off.
9. COLOR CODES:
BA: white OR: orange
BE: blue RG: red
BG: beige RS: pink
GR: gray VE: green
JN: yellow VI: mauve
MR: brown VJ: green/yellow
