 In the presence of one of the signs specified first of all they execute an ordinary diagnostic proceeding, including the check of the main systems of the motor. After that check elements of a system of control of the motor through the device HI-SCAN (in stations of service of the cars of Hyundai).
 The sensor of the concentration of oxygen with the heating is joined to protected wires of EBU, the fabrics are joined "to the mass" of a body of the protection against hindrances against the system of the ignition and a radio-noise. In the fabrics damage they substitute wires.
When there checks the load of the creator not desconecta a wire of the positive capture ("+") of the battery recarregável to prevent the damage of EBU for the increased tension.

       Notes
     Before the removal or the installation of some of elements of the system consider codes of bad functioning, soon desconectem a wire of the negative capture ("-") of the battery recarregável.
  Before a lack of interest of wire of the negative capture of the battery recarregável they put the ignition out. The lack of interest or the connection of wires of the battery in the motor of work or the included ignition can cause damage of one unity of electronic control.

In the porter of provision of extern power of the battery recarregável desconectam a wire of the negative capture of the battery recarregável not to damage EBU.

With bad functioning in a system of control of the motor the control lamp (fig.) it illuminates 2.197 and 2.198. If the bad considered functioning is not shown after three consecutive cycles of the Repair of the motor, the lamp is extinguished slowly. The lamp illuminates at the same time after the inclusion of the ignition (without the launch of the motor) what indicates his usefulness.
The conditions during the creation of some of which the control lamp illuminates:
– the catalytic converter is defective;
– the system of provision of power of motor is defective;
– the sensor of the absolute pressure is defective;
     – the sensor of the temperature of the soaked air is defective;
     – the sensor of the temperature of cooling the liquid is defective;
 – the sensor of the provision of a valve of butterfly is defective;
– the best sensor of the concentration of oxygen is defective;
– the heating of the lowest sensor of the concentration of oxygen is defective;
– the lowest sensor of the concentration of oxygen is defective;
– the heating of the best sensor of the concentration of oxygen is defective;
– the mouths are defective;
– admissions of ignition of mixture;
– the sensor of the provision of an end of inclination is defective;
– the sensor of the position of the axle is defective;
– the system of the capture of steams of the fuel is defective;
– the sensor of the speed of the movement of the car is defective;

  Lamp of control of bad functioning of a system of control of the motor (cars without the system of European side of diagnostic one)
Illuminating, the control lamp warns the driver on the existence of the bad functioning in a system of control of the motor. Nevertheless, if the bad considered functioning is not shown after three consecutive cycles of the Repair of the motor, the lamp is extinguished slowly. The lamp illuminates straightly after the inclusion of the ignition (without the launch of the motor) what indicates his usefulness.
The conditions during the creation of some of which the control lamp illuminates:
– the heated sensor of the concentration of oxygen is defective;
– the sensor of the absolute pressure is defective;
 – the sensor of the provision of a valve of butterfly is defective;
    – the sensor of the temperature of cooling the liquid is defective;
– the regulator that wastes time is defective;
– the mouths are defective;
– the unity of control of the motor is defective.
For the check be convinced that after the inclusion of the ignition the lamp is burned approximately during 5 with, and soon it is extinguished slowly.
If it does not illuminate the lamp, it breaks then of wire, the burn - out of a lock of security or the lamp is the possible reason.

System of autodiagnostic one
The unity of control of the motor gives the Repairal orders of mechanisms of actuation and prosecutes signs of sensors (some teams and signs constantly, others – only below certain conditions). If EBU finds an aberration, it writes a diagnostic code of the bad functioning and gives a sign in the capture of contact of a line of data. The result of the diagnostic one is exposed by the fire of a lamp of control of the bad functioning or in the device HI-SCAN. The diagnostic codes of the bad functioning guard in the memory of EBU even in him tension of the movements of battery you were re-overdoing. The codes of the bad functioning are withdrawn in a lack of interest of the battery recarregável or the separation of the capture of contact of EBU or they put out through HI EXAMINATION diagnostic unity.

       TO OBSERVE
In a lack of interest of the capture of contact of any sensor in the ignition included in memory of EBU the registers of code of bad functioning. In this case it is necessary to withdraw a code of bad functioning, having desconectado a wire of the negative capture ("-") of the battery recarregável.

Work of system of side of diagnostic one
1. If the same bad functioning is and remains during two cycles of a travel, the lamp of control of the bad functioning of a system of control of motor automatically illuminates.
 2. The lamp of control of the bad functioning of a system of control of the motor is extinguished slowly if during three cycles of successively the bad functioning they are not.
 3. The diagnostic code of the bad functioning (DTC) is registered in the memory of EBU in the moment of the detection of failure after two cycles successively. The lamp of control of the bad functioning of a system of control of the motor illuminates in the moment of the detection of failure in the second cycle.
In the moment of the detection of the admission of the ignition of the mixture the registers of code of bad functioning and the lamp of control of the bad functioning of a system of control of the motor are illuminated by it straightly after the failure detection.
4. The code of bad functioning automatically is withdrawn of the memory of EBU if the same bad functioning is not during 40 cycles.

       Notes
The cycle of be heating of the motor corresponds to the sufficient time of his work during which temperature to cool liquid increases of the moment of the launch of the motor not less than for 4,5 °C and not below of 70 °C they get the value.
The cycle of a travel includes the launch of the motor and the movement of the car after the beginning of the agreement of the composition of the mixture in signs of sensors of the concentration of oxygen.

The codes of bad functioning happen in the etiquette. 2.5.

Sensor of absolute pressure
The sensor of the absolute pressure (MAP) happens in the form of the sensitive variable resistor to the modification of the pressure. The sensor measures modifications of the pressure in the entry oil pipeline depending on modification of the load and frequency of the rotation of an end of inclination of the motor and it will transform them to the tension of a sign of production. The sensor measures also atmospheric pressure in the moment of the launch of the motor and below some conditions EBU supplies an opportunity to conform automatically in values different from the height above the sea level. EBU gives the voltage of provision of 5 V in the sensor and prosecutes the signs of sensor transmitted in a chain of transmission of sign. The sensor is joined "to the weight" he was seeing the built variable resistor. Depending on a sign of the sensor EBU it regulates the duration of the provision of the fuel and a corner of an advancement of the ignition.

 What must be known to an owner of the car with the injector motor 
The injector motors surpass the carburator in many parameters, to take at least his profitability and launch without problems in a frost. However the carburator below our conditions sometimes is more advantageous. Some manufacturers of the cars even hand in our market cars with such motors. It is everything on the quality of gasoline that is sold in us.
The injector motor calculates second to gasoline of first quality that in our petrol stations will find infrequentemente. Besides systems different from the injection they have the specific characteristics, have to consider themselves in the moment of the Repair of the car. And in our market there are most of such systems: mechanic –
K-Jetronic (KE-Jetronic), eletromecânico – L-Jetronic and electronic – Motronic, Lucas, Magneti Marelli.
Many systems have two Repairal ways: the principal and emergence used in bad functioning of one of sensors. The driver cannot notice such a bad functioning: in the panel there is no lamp of corresponding control, and the motor keeps on working (but not in the best way more). Similar quite very often it gives with the cars of equipped Audi of motors with the central injection of the fuel. Approximately a third of the drivers who have such cars even does not guess what enter in the emergence Repair. And it leads to the consumption of increased fuel, slowing down of power, unequal Repair of the motor and the complicated launch. The bad functioning only in the moment of the next maintenance comes to the light. Therefore, there are worthwhile there stretch out "weak" places of the systems of the injection that are shown below our conditions.
Systems with mechanical injection. They more than others, they are subject to the physical use. The regulator of the faulty pressure of the fuel normally for 80-120 thousand km of a race (the launch of motor considerably gets worse), the mouths – for 60-80 thousand km (the unequal Repair of the motor, the consumption of increased fuel). The mouths refusal is specially cunning how it will notice it not at the same time. The diagnostic one and the repair need the special equipment. 
Painful systems point with injection eletromecânica – an air suction for the numerous hoses of vacuum that tend to crack after 4-5 years of service. Specially in the cars BMW and in a little less degree in Audi. To define such a quite difficult defect.
Electronic injection systems. They have problems. For example, the accumulator "sat down", and you in an old resolved habit "to the light" of another car. Since that the unity of electronic control of the system of the faulty injection. And the gasoline use ethylated, to his time, puts out of the commission the sensor of the concentration of oxygen (it tries of lambda) and catalytic converter.
In general so much the mechanical systems, since electronic of the injection they have the advantages and minuses. In the mechanic the bush is refused by gas pumps and distributors batchers.
In the electronic one the gas pump is more lasting and is cheaper, but the elimination of any bad functioning of one unity of electronic control will cost very much. Besides, oh, we have more reasons of the failure of any system, of which in Europe: to gasoline of low quality, the dirt in ways and chemical products that they spread in winter. Therefore, it is worthwhile to listen to experts' recommendations. There if will be an opportunity, since the removal of the moisture of lines of supply of fuel during each stuffing they fill out the special medicine in a tank; for everyone
10 000-15 000 km of a race do the washing full of the system of the injection.
