Fig. 1.28. Switch of a cleaner and washer of a windshield: I \switch of the choice of the block of memory; II \the button of switching of the output information

Switching of the output information on the display (fig. 1.27) is carried out by pressing of the button II (fig. 1.28) on the switch of a cleaner and washer of a windshield at the included ignition.

Information in the on-board computer is stored in two blocks of memory of "MFA 1" and "MFA 2". Depending on what data are output to the display, number of the block of memory is highlighted.

Information on a separate trip from the moment of inclusion of ignition and before its switching off collects in the block of memory of "MFA 1" of the on-board computer and includes data on time of the movement, the passable distance and amount of the spent fuel. On the basis of these data the computer counts the average speed of the movement and average fuel consumption.

If the movement is resumed within two hours after a stop and switching off of ignition, data on the previous trip to memories of the on-board computer remain, and the new arriving data will be added to them. If time between trips exceeds two hours, all information in memory of the on-board computer "will be nullified".

The block of memory of "MFA 2" for storage of the general data on operation of the car summarizes and processes results of separate trips which general duration makes 100 h, a total run – 10 000 km and total of the spent fuel – 1000 l. In case of excess of one of the called indicators the block of memory of the computer erases information and starts new counting from scratch.

The choice of indication of data of the corresponding block of memory is carried out by the switch I (see fig. 1.28 ). For removal of information it is necessary to execute the following operations from the block of memory of the on-board computer:

– to include ignition;

– to transfer the switch I to situation "1" or "2" (for the choice of the corresponding block of memory);

– to translate the switch I and to hold it more than one second in situation "0" (near the provision of turning on of the corresponding block of memory).

If on the display there is no symbol "MFA 1" or "MFA 2", then it shows daily time even at the switched-off ignition.

The information display (see fig. 1.27 ) shows the following data:

– time of the movement of the car.

If the switch I (see fig. 1.28 ) is in situation "1", then on the display time of the movement of the car is displayed from the moment of inclusion of ignition or the moment of "zeroing" of the block of memory of "MFA 1". If the switch I is in situation "2" – the display shows total time of all trips. The maximum total time makes 99 h 59 min. at which achievement its counting starts from scratch.

– the distance passed by the car. Information on the distance passed by the car is received similar to information on time of the movement of the car. The maximum total run of the car information on which to be stored in the block of memory of "MFA 2" of the car makes 9999 km. At achievement of this size data in the on-board computer "are nullified".

– average speed of the movement  of the car. After inclusion of ignition information on the average speed of the movement of the car appears on the display after passing of the first 100 m of a way. Up to this point on it instead of figures strokes are highlighted. If the switch I is in situation "1", on the display the current average speed of the movement of the car is shown; if the switch I is in situation "2" – the average speed of all trips.

– average fuel consumption.

In this mode data on average fuel consumption are highlighted.

– oil temperature to la's dvigata. Value of temperature of oil is brought to the display in the range from +50 to +160 °C. If temperature of oil of the engine did not reach +50 °C, then on the display instead of figures strokes are highlighted. If temperature of oil is above +145 °C, it is necessary to reduce load of the engine.

– air temperature outside of  the car. Value of air temperature outside of the car is brought to the display in the range from-40 to +50 °C. After switching off of ignition data on external air temperature remain within 45 min. At renewal of the movement the valid value of air temperature will be received at achievement by the car of speed of the movement of 30 km/h.
