7.5.1. Features of the device

Headlights

Fig. 7.18. Scheme of inclusion of headlights and fog light: 1 – block headlights; 2 – assembly block; 3 – switch of light of headlights; 4 – ignition switch; 5 – switch of external lighting (fragment); 6 – lamps of fog light in internal back lamps; 7 – the switch of fog light with a control lamp of inclusion; 8 – a control lamp of driving beam of headlights in a combination of devices; K8 – the relay of inclusion of driving beam of headlights; K9 – the relay of inclusion of passing beam of headlights; And — an order of conditional numbering of plugs in a block headlight block; In — to power supplies

The scheme of inclusion of headlights is shown in fig. 7.18. Driving and passing beam of headlights is turned on by means of auxiliary K8 and K9 relays. The operating tension on windings of the relay moves from the switch 3 lights of headlights if the right key of the switch 5 of external lighting is pressed.
Irrespective of the provision of keys of the switch 5 it is possible to turn on quickly driving beam of headlights, delaying on itself the switch lever 3 lights of headlights. At the same time tension to contact "30" switches 3 moves from contact "30" switches 4 ignitions.
Fog lights

Fig. 7.19. Scheme of inclusion of fog lights: 1 – fog lights; 2 – relay of inclusion of fog lights; 3 – assembly block; 4 – the switch of fog lights with a control lamp of inclusion (at the left) and an illumination lamp (on the right); 5 – switch of external lighting (fragment); And — to power supplies; In — to the regulator of lighting of devices

On cars in alternative execution in front bumpers fog lights can be established. The scheme of inclusion of fog lights is shown in fig. 7.19. Headlights join the switch 4 by means of the auxiliary relay 2 of the type 113.3747-10 established in a motor compartment on the left mudguard. Fog lights can be included only if external lighting is included by the switch 5.
External lighting

Fig. 7.20. Scheme of inclusion of external lighting: 1 – lamps of dimensional light in block headlights; 2 – podkapotny lamp; 3 – assembly block; 4 – switch of a podkapotny lamp; 5 – ignition switch; 6 – switch of external lighting (fragment); 7 – a control lamp of external lighting in a combination of devices; 8 – lamps of dimensional light and a stoplight in external back lamps; 9 – lamps of illumination of registration plate; 10 – regulator of lighting of devices; 11 – stoplight switch; 12 – block of the onboard control system; K4 – the relay of control of serviceability of lamps (in the relay contact crossing points which have to be established in the absence of the relay are shown); And — to power supplies; In — to lamps of illumination of switches and devices; With — to an additional signal of braking

The scheme of inclusion of external lighting is shown in fig. 7.20. The dimensional light is turned on by the switch 6 of external lighting.
Food of lamps of dimensional light and stoplight occurs via the K4 relay of control of serviceability of lamps. If fuses any of lamps, then the relay includes the corresponding LED signaling device in the block 12 indications of the onboard control system.
If the relay of control of serviceability of lamps is not installed in the assembly block, then instead of it there have to be contact crossing points shown by shooters in fig. 7.20.
Indexes of turn

Fig. 7.21. Scheme of inclusion of indexes of turn and alarm system: 1 – lamps of indexes of turn in block headlights; 2 – assembly block; 3 – ignition switch; 4 – switch of the alarm system; 5 – side indexes of turn; 6 – lamps of indexes of turn in external back lamps; 7 – a combination of devices with control lamps of indexes of turn; 8 – switch of indexes of turn; K2 – the relay breaker of indexes of turn and the alarm system; And — to power supplies

The scheme of inclusion of indexes of turn and the alarm system is shown in fig. 7.21. Indexes of turn of the right or left board join the switch 8. In the mode of the alarm system the switch 4 all indexes of turn join. The blinking of lamps is provided to the K2 relay breaker in the assembly block.
