Fig. 1.7. Combination of devices

The arrangement of devices and signaling devices in a combination of devices is shown in fig. 1.7.
In a combination of devices the following devices and signaling devices are installed.
1 – tachometer. Shows the frequency of rotation of a bent shaft of the engine. The scale has divisions from 0 to 7, the price of division 0,5. To learn the frequency of rotation of a bent shaft in min.-1, it is necessary to increase indications of a tachometer for 1000. A zone of a scale of red color — an operating mode, dangerous to the engine. Do not allow excess of most allowed frequency of rotation of a bent shaft of the engine (a threshold – 6000 min.-1).
2 – the control lamp of inclusion of the left index of turn (with the light filter of green color in the form of an arrow) lights up the blinking light at inclusion of the left index of turn (synchronously with it). The blinking of a control lamp with the doubled frequency signals about burn-out of a lamp in any index of turn.
3 – the speedometer of induction type shows with what speed the car moves at present. The scale is graduated by from 0 to 200 km/h, the price of division of 10 km/h. The speedometer drive electric from the sensor installed on a transmission case.
4 – a control lamp of inclusion of the right index of turn (see item 2).
5 – the index of temperature of liquid in the engine cooling system. If the arrow of the index enters a red zone (more than 115 °C) that means an engine overheat, then is distributed constant (during 5 c) a sound signal. It will repeat until the arrow does not leave a red zone (less than 110 °C). If the arrow is in a red zone, it is necessary to stop, allow to the engine to cool down and remove the overheat cause.

Prevention
Do not allow operation of the car with the superheated engine as it will lead to serious breakages of the engine.

6 – index of level of fuel. Transition of an arrow to a red zone of a scale indicates the need refuellings in order to avoid interruptions in operation of the engine.
7 – alarm lamp of the reserve rest of fuel. Lights up orange light in need of refueling of the car in order to avoid interruptions in operation of the engine. Along with fire of an alarm lamp is distributed faltering (2 repeated inclusions / switching off lasting 0,25 c) sound signal.

Prevention
Never allow full fuel use. It can lead to damage of the fuel pump and to an emergency because of a stop of your car on the road.

8 – button of dumping of indications of the counter of a daily run and switching of operating modes of the liquid-crystal display of the route computer. Install by pressing the button at the motionless car on zero the counter of a daily run in the liquid-crystal display or choose the mode of display of a daily or general run.
9 – a control lamp of turning on of the alarm system (with the light filter of red light). Lights up the blinking light at turning on of the alarm system.
10 – a control lamp of the electroamplifier of steering (it is connected if the electroamplifier of steering is installed on the car). Lights up orange light at inclusion of ignition and dies away after launch of the engine.

Prevention
Fire of a control lamp of the electroamplifier of steering at the working engine indicates malfunction of the electroamplifier which needs to be eliminated. Operation of the car with faulty steering is life-threatening.

11 – the control lamp of inclusion of driving beam of headlights (with the light filter of blue color) indicates inclusion of driving beam of headlights.
12 – the control lamp of inclusion of external lighting (with the light filter of green color) indicates inclusion of marker lights in headlights and back lamps.
13 – the control lamp of turning on of the parking brake (with the light filter of red color) lights up at the included ignition if the car is slowed down by the parking brake.
14 – an alarm lamp of safety cushions (it is connected if safety cushions are installed in the car). Lights up orange light at inclusion of ignition and after launch of the engine dies away.

Prevention
At fire of an alarm lamp in all other cases immediately address in service. Besides possible refusal in an emergency, it can unexpectedly work during the movement that will lead to serious consequences.

15 – the alarm lamp of emergency pressure drop of oil (with the light filter of red color) lights up at inclusion of ignition and warns that pressure in the lubrication system of the engine is lower than norm.
At the working engine the burning alarm lamp and constant (during 5 c) the signal of a buzzer is pointed to insufficient pressure in the engine lubrication system.

Prevention
Operation of the car with the faulty lubrication system can lead to serious breakages of the engine.

16 – control lamp of an immobilizator. Lights up orange light and displays a condition of an immobilizator, for more details see. "Management of electronic anticreeping system)".
17 – liquid-crystal display. The top line displays for choice the general or daily run, and the lower line — time, temperature of external air or function of the on-board computer.
18 – an alarm lamp of not fastened seat belt of the driver (it can be connected in alternative execution). Lights up red light at inclusion of ignition if do not fasten a seat belt of the driver. Along with fire of a lamp the buzzer signal is distributed faltering (5 repeated cycles).
19 – the alarm lamp of the category of the rechargeable battery (with the light filter of red color) lights up at inclusion of ignition. Burning of a lamp is followed faltering (5 repeated inclusions / switching off on 0,5 c) a buzzer signal. Right after launch of the engine the lamp has to go out. Burning of a lamp or its luminescence dimly at the working engine indicates the lack of charging current caused by malfunction of the generator or regulator of tension or a weak tension (break) of a belt of the drive of the generator.

Prevention
The movement of the car with the burning lamp is forbidden as, besides the full category of the rechargeable battery, it can indicate short circuit in charging chain that it is fraught with the fire.

20 – an alarm lamp of critical condition of the brake system (with the light filter of red light). Lights up at inclusion of ignition and dies away after launch of the engine. Fire of a lamp of critical condition of the brake system and a signal of a buzzer (5 repeated inclusions) at the working engine demonstrate falling of level of brake fluid below a tag of "MIN" on a tank of the main cylinder of a brake.

Prevention
Operation of the car with the faulty brake system is forbidden.

21 – an alarm lamp of the disconnected safety cushion of the forward passenger (it is connected in alternative execution).
22 – an alarm lamp of malfunction of the electronic distributor of brake forces (it is connected in alternative execution). The lamp lights up red light at inclusion of ignition and through 2 with dies away (the self-testing mode).
23 – an alarm lamp of anti-blocking system of brakes (it is connected in alternative execution if on the car the anti-blocking system of brakes is installed). The lamp lights up red light at inclusion of ignition and through 2 with dies away (the self-testing mode). Burning of a lamp at the working engine indicates malfunction of anti-blocking system.

Prevention
In all other cases fire of an alarm lamp of anti-blocking system of brakes demonstrates emergence of malfunction which needs to be eliminated at specialized service station as braking happens without ABS participation.

24 – an alarm lamp "CHECK the ENGINE". Lights up orange light at inclusion of ignition and after launch of the engine dies away.

Note
Burning of an alarm lamp "CHECK the ENGINE" at the working engine it is caused by malfunction of a control system of the engine (system of injection of fuel). It does not mean that the engine needs to be stopped immediately as in this case the control system of the engine switches over to the emergency operation allowing the engine to work in the conditions close to normal. However the cause of defect needs to be removed as soon as possible because long operation of the car with the burning lamp can lead to increase in fuel consumption, deterioration in traction characteristics of the car and to breakages of the engine.
