Diagnostics of malfunctions of system of ignition and check of a condition of its components
System of static ignition Simos On the models equipped with system of ignition Simos 2P where the distributor is not provided, forces of the average mechanic-fan the narrowest spectrum of checks can be made only. In case of occurrence of any problems connected with infringement of functioning of system of ignition always first of all check quality of contact connections of electroconducting on the bobbin module and the gauge of turns and positions of a cranked shaft. Also estimate a condition of isolation of electroconducting. Check up quality of landing of the bobbin module on all spark plugs. Also check up a condition actually candles - remember that candles in systems of ignition with a single spark are subject to the raised deterioration. Remove the gauge of turns and position of a cranked shaft and attentively study its condition (see Has undressed Removal and installation of information gauges of system of ignition). If during performance listed above checks to reveal a cause of infringement it is not possible, the car should be driven away for more detailed diagnostics of system of ignition on a firm car repair shop of company Skoda. All other systems The most typical causes of failures The majority of refusals of systems of ignition appear connected with infringement of quality of contact connections of a chain, or with current leaks in ВВ a contour. Leaks usually occur owing to formation of the coal paths appearing as a result of electric breakdowns at excessive pollution, humidifying or mechanical destruction of components. Before to make the decision on replacement of a suspected component always at first check electroconducting. Work without hurrying up, methodically checking each of separate sites of a chain, trying to reveal a method of exceptions the damaged sector. In overwhelming majority of cases spraying of a surface of components ВВ of a contour of system special влагопоглотителем type WD40 helps. Check spark presence can in become habitual way by a present of a wire of a food to the engine block in this case it is not recommended, not only in view of the raised risk of reception of an electroshock, but also in order to avoid failure ВВ of a contour of the coil. It is not necessary also to try to reveal the cylinder in which ignition admissions, by a serial detachment of wires from each of candles take place. The engine is not started If the engine is not turned at all, or rotates too slowly, check up a condition of the storage battery and a starter. Connect the voltmeter between polar plugs of the battery (with polarity observance: “+” to “+”; “-” to “-”). Disconnect from a cover of distributor VV a wire of the coil of ignition and earth it on a car-care centre workshop. Consider an instrument reading at проворачивании the engine as a starter (do not turn the engine continuously more than 10 seconds). If the result of measurement makes less than 9.5 In, check up a condition of the battery and serviceability of functioning of systems of start and a charge. If the engine is turned with normal speed, but thus is not started, it is necessary to check up ВВ a contour of system of ignition. Following instructions of manufacturers, connect a stroboscope, then turn the engine a starter. If the stroboscope regularly blinks, hence pressure moves on spark plugs and it is necessary to check up a condition of the last. If the stroboscope does not react on проворачивание the engine, check up a condition actually ВВ wires, then distributor covers, coal contact brushes and бегунок. If infringements in искрообразовании are not present, check up serviceability of functioning of the power supply system. Cause of infringement искрообразования malfunction in НВ parts of system of ignition can be. Check up serviceability of giving of a food in 12 In on the ignition coil. Estimate a condition of contact connections and electroconducting. Check up actually the coil. The reason of absence of a food on the coil malfunction of the switch of ignition, or safety lock combustion can be. Remember that malfunction of system of the anticreeping alarm system or иммобилизатора the engine can be at the bottom of an engine failure from start. Before to continue checks, make sure that the anticreeping system is properly disconnected. If to reveal a cause of infringement искрообразования during the spent checks it is not possible, it is necessary to drive away the car on a car repair shop for performance of diagnostics of malfunctions of a control system by the engine. Ignition admissions take place Stability infringement искрообразования results from infringement of quality of contact connections or occurrence of changeable defect in НВ a system contour more often. The second reason of admissions of ignition is malfunction ВВ of a contour of system, or damage of the bobbin party бегунка. In certain cases to infringement of stability of ignition conduct refusals of the gauge of turns and position of a cranked shaft/hall (see Has undressed Removal and installation of information gauges of system of ignition). At the switched off ignition carefully check up an external condition of all components of system, special attention giving to quality of contact connections. At presence near at hand the necessary equipment check up a condition of electroconducting and quality of contact connections НВ of a contour of ignition. Make sure that ВВ the ignition coil, a cover of the distributor and ВВ wires are free from a dirt and a moisture. A method of substitution of obviously serviceable components check up condition ВВ of wires and spark plugs, then examine a cover, coal brushes and бегунок the distributor. Regular admissions of ignition with high degree of probability appear are connected with damages of a cover of the distributor., ВВ wires or spark plugs. By means of a stroboscope make sure available ВВ pressure of a food on candles. If ВВ the signal on one of сечей is absent, a cause of a failure is malfunction given ВВ wires or distributor covers. In the presence of pressure on all candles it is necessary to check up a condition of each of them separately. Absence ВВ of pressure on all spark plugs speaks about malfunction of the coil of ignition - its secondary winding can appear is punched as a result of influence of high electric loadings. Other infringements If to reveal a cause of infringement during performance listed above checks it is not possible, it is necessary to address for the help to experts of car-care centre.
