Built in a broad tank, the sensor of level of liquid (shooter) signals about amount of cooling liquid available in a tank.
At the cars equipped with system of self-examination, similar devices by determination of malfunction of lamps supervise serviceability of illumination of the car. The device by determination of malfunction of lamps of back dimensions of a sedan is located at the left in a luggage compartment. Approximately on the same place it is located and at the versatile person (Avant). The device by determination of malfunction of lamps of forward illumination of the car is located in the additional block of the relay under the dashboard.
As the special equipment of Audi offers self-examination system. She watches eight functions, or operational sostoyany, after inclusion of ignition and after inclusion of a passing beam or a brake signal. Active control is carried out and during movement. Thereby the system of autocheck replaces a number of ordinary indicators available in standard option.
Indicators of the malfunctions, which board is in the middle of a combination of devices, are divided into groups «Danger signal» and «A prevention signal».
The malfunctions which are essentially influencing traffic safety or serious damages having by the consequence, are considered dangerous and consequently signals light up red color. These are the following signals:
Brake system: too low level of brake liquid.
Pressure of engine oil: pressure of oil in a mode of idling falls below 0,3 bar, or at the frequency of rotation exceeding 2100 rpm, indicators 1,8 bar (model with 4-and 5-cylinder engines) or 2,5 bar (model with 6-cylinder engines) are not reached.
Cooling liquid: the temperature of cooling liquid rises above 120°С, or the working temperature, or too low level of cooling means is not reached.
In addition to a light signal of danger from a combination of devices the triple buzzer proceeds. Signals of danger have in system a priority before safety signals. Until there is a danger signal, the warning signal chokes. It appears only after elimination of the reason of a signal of danger.
Warning signals are highlighted on the panel by yellow color and accompanied by a single buzzer. These are the following signals:
Stoplight: this symbol appears right after ignition inclusion. If to press a brake pedal, the symbol disappears – provided that both brake lamps function.
Lighting: the system of self-examination cannot execute this verifying stage completely automatically. At first the driver should include a passing beam. The passing beam and back dimensions are at the same time supervised. Simultaneous refusal of both filaments of a passing beam or back dimensions system to show unable, but generally this malfunction hardly can occur.
Storage battery: the symbol of the storage battery flashes, if storage tension falls outside the limits standard indicators 10,6 — 15,6 Century.
System of washing of glasses: this indicator indicates too low level of washing liquid in a tank.
Fuel tank: the symbol of filling lights up, if in a fuel tank there are only 12 l of gasoline.
If on a board of warning signals there are some malfunctions, warning signals flash in turn, at ignition inclusion.
The signal "OK" should appear, if after inclusion of ignition and pressing a pedal of a brake the inscription «Bremslicht» (stoplight) went out. "OK" in this case means that all stages of check were passed without messages on malfunctions. Later short time the signal dies away.
Devices by determination of serviceability of lamps
These devices work at an electromagnetic principle and compare a current passing in conducting, for example, to the left and right passing beam. If in any wire because of a gap or defect of a lamp is not present a current expense, the control device establishes a difference and reports about it to the control unit. In case of malfunction of both lamps that occurs very seldom, naturally, also it is not noted differences. In this case the control device unable to establish malfunction.
Help: at socket connection for the trailer it is necessary to watch, that connection of wires to back dimensions was made earlier, than to the device of determination of serviceability of lamps (it is located behind at the left in a luggage compartment). If a food to take from one of back dimensions, at connected illumination of the trailer in the device of determination of serviceability of lamps unrecorded data on currents in a chain arrive, and he reports about «defect of a lamp».
Removal of the control module
The control unit of system of autocheck is screwed on a reverse side of a combination of devices in one case with the block of indicators. You will find the description of removal of the module of system of autocheck in the beginning of this chapter in the section "Dismantling".
Search of malfunctions of system of self-examination
Control of system of self-examination in house conditions is possible only partially: at first it is necessary to check all sensors – if here malfunction was not found, means, she should be looked for in the module of system of self-examination.
- Sensors are checked the same as at check of indicators of the ordinary dashboard.
- The water level sensor in system of cooling which is established only in autocheck system, is checked as follows: if the indicator burns despite full tanks of system of cooling, it is necessary to separate cable tips at a tank. If now the warning signal dies away, means, the sensor is faulty.
- Check of devices by determination of malfunctions of lamps as lobbies (an installation site: the additional block of the relay at the left under the dashboard), and back (an installation site: at the left) you should provide a luggage compartment to a workshop.
Independent control of the block of indicators
- To press at the included ignition and standing (or 5 km/h moving with the maximum speed) the car the button at the left below combinations of devices.
- If indicators and system are serviceable, on the dashboard there should be in turn all signals symbols.
- Similar check is impossible, if the danger signal burns.
Additional functions on a board of system of self-examination
Prevention of speed: after record of speed of movement at present time (at desirable speed) the system of autocheck indicates by pressing of the left button combinations of devices essential excess of this speed by emergence of a symbol and a buzzer. This record remains up to ignition switching off in case other speed of movement was not written down or memory (the extreme left button to hold pressed within a second) is erased.
Indicator of radio frequencies: if the field of indicators is not occupied with information from self-examination system, on it there are data on frequency of radio stations on the autoradio tape recorders equipped as appropriate. In addition the board of indicators informs on stereoreception or the enclosed cartridge (Tape). If radio stations transmit also signals of system of radio data, in the field of indicators there is «RDS» inscription. Then on the radio display it is possible to read the radio station name.
