As special equipment Audi offers self-examination system. She observes for восемью functions, or operational состояними, after inclusion of ignition and after inclusion of a passing light or a brake signal. The active control is carried out and during movement. Thereby the autocheck system replaces a number of usual indicators available in a standard variant.
In addition to a light signal of danger from a combination of devices the triple buzzer proceeds. Danger signals have in system a priority before safety signals. Until there is a danger signal, the warning signal chokes. It appears only after liquidation of the reason of a signal of danger.
Warning signals are highlighted on the panel by yellow colour and accompanied by a unitary buzzer. These are following signals: Stoplight: this symbol appears right after ignition inclusions. If to press a brake pedal, the symbol disappears – provided that both brake lanterns function. Illumination: the self-examination system cannot execute this verifying stage completely automatically. At first the driver should include a passing light. The passing light and back dimensions are simultaneously supervised. Simultaneous refusal of both incandescent filaments of a passing light or back dimensions system to show not in a condition, but generally this malfunction hardly can occur. The storage battery: the symbol of the storage battery flashes, if storage pressure falls outside the limits standard indicators 10,6—15,6 Century System of washing of glasses: this indicator specifies in too low level of a washing liquid in a tank. Fuel tank: a refuelling symbol загарается 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 by turns, at ignition inclusion. The signal ОК should appear, if after inclusion of ignition and pressing a brake pedal the inscription Bremslicht (stoplight) has gone out. ОК in this case means that all stages of check have been passed without messages on malfunctions. After short time the signal dies away.
Devices by definition of serviceability of lamps
These devices work on an electromagnetic principle and compare a current which is passing in conducting, for example, to the left and right passing light. If in any wire because of rupture or defect of a lamp is not present the current expense, the control device establishes a difference and informs on it to the management block. In case of malfunction of both lamps that occurs very seldom, naturally, also it is not marked differences. In this case the control device not in a condition to establish malfunction.
Removal of the control module
The block of management of system of autocheck is screwed on an underside 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 section "Dismantling".
Search of malfunctions of system of self-examination
The control of system of self-examination in house conditions is possible only partially: at first it is necessary to check up all gauges – if here malfunction has not been found, means, it is necessary to search for it in the module of system of self-examination.
The independent control of the block of indicators
Additional functions on a board of system of self-examination
The prevention of speed: after record of speed of movement at present (pressing of the left button combinations of devices at desirable speed) the autocheck system specifies to time in essential excess of this speed by occurrence of a symbol and a buzzer. This record remains up to ignition deenergizing in case other speed of movement has not been written down or memory (the extreme left button to hold pressed within a second) is erased.
The indicator of radio frequencies: if the field of indicators is not occupied by the information from self-examination system on it there is data about frequency of radio stations on the autoradio tape recorders equipped in appropriate way. In addition the board of indicators informs on stereoreception or the enclosed cartridge (Tape). If radio stations transfer also signals of system of the radio data in the field of indicators there is an inscription RDS. Then on the radio display it is possible to read the radio station name.
