Diagnostics of malfunctions In the given Section the most simple scheme of finding-out of the reasons of malfunctions and the refusals occurring in knots and systems of a vehicle is offered. Refusals and their possible reasons are broken into groups on the basis of the relation to certain components or car systems, as for example the engine, cooling system, etc., besides, in the text references to Chapters and Sections concerning the given problems are given.Remember that successful end of search of causes of defect at all is not the black magic accessible to only skilled professional mechanics, and is defined by a combination of certain knowledge and the patient, regular approach to problem research. To move always follows from simple to difficult, to lead up each check to the logic end and to try not to pass the obvious facts – everyone can forget to fill fuel in a fuel tank or to leave for the night included lighting devices. And at last, always it is necessary to try to make an accurate picture of development of malfunction and to undertake corresponding steps on relapse prevention. If refusal of an electric equipment was the result of infringement of quality of contact, check up at the same time a condition of all other contacts and electric sockets of system. If the same safety lock some times continues to fuse successively, there is no sense in its further replacement – it is necessary to try to find out a cause of a failure. Remember that failure of a minor component can be a sign of infringement of functioning of more important knot or the whole system.

Features of specialised automobile diagnostic device ADC2000: the Built in 4-channel oscilloscope with standard preset for 19 gauges. the Analyzer of system of ignition for check primary and secondary chains (with pressure to 100кВ) on systems with the distributor or separate coils of ignition – with the control of time of burning, peak value of pressure, a corner of an advancing of ignition, a current, and turns. the Two-channel multimeter with digital and graphic data presentation on pressure (150В), frequency (1100кГц), a current (150А). the Built in scanner for the basic systems on cars: VAG, MB, BMW, Volvo, Toyota/Lexus, Mitsubishi, Nissan, Honda, Mazda, GM, Ford, Chrysler, Daewoo, Hyundai, Kia, Samsung, and so on cars supporting report OBD–II. cartridges are not required – you can execute updating of programs of the device, having downloaded necessary updatings from the Internet. Programnoe maintenance for communication with the personal computer. The information on use of these devices contains in applied documents. About these devices you can get acquainted with details on sites www.programatools.com, www.lasn.com. For diagnostics carrying out we recommend to you to address for the qualified help of experts HUNDRED.
Contacts of a diagnostic socket for used reports: ISO 9141–2 Contacts 4, 5, 7, 15, 16 J1850 PWM Contacts 2, 4, 5, 10, 16 J1850 VPW Contacts 2, 4, 5, 16 (without 10) Report ISO 9141–2 (for Europe and Asia) is identified by presence of contact 7 and absence of contacts 2 and-or 10 on a diagnostic socket. Reports SAE J1850 VPW (Variable Pulse Width Modulation) – General Motors – or SAE J1850 PWM (Pulse Width Modulation) – American Ford – are identified by absence of contact 7. All three reports of data exchange work through standard cable OBD–II J1962. № a conclusion Appointment 1 It is set by the manufacturer 2 Line Bus +, SAE J1850 3 It is set by the manufacturer 4 Connection with the case 5 Case – an alarm conclusion 6 It is set by the manufacturer (CAN high level, J–2284) 7 Line K, ISO 9141 8 It is set by the manufacturer 9 It is set by the manufacturer 10 Line Bus – SAE J1850 11 It is set by the manufacturer 12 It is set by the manufacturer 13 It is set by the manufacturer 14 It is set by the manufacturer (CAN Low level, J–2284) 15 Line L, ISO 9141 16 Plus of the battery through a safety lock.

Appointment of conclusions
The engine If the engine is not started, it is necessary to analyse a situation. That the engine in general could be started, two basic conditions should be satisfied. In cylinders the mix should arrive fuel-air, and on a spark plug the spark should be developed. Therefore, first, it is necessary to check up, whether fuel moves. As thus it is necessary to operate, it is described in the Head of the Power supply system, injection and release. To define, whether the spark is developed, it is necessary to turn out candles, to insert into tips and separately to put to weight. Thus a tip or a cable of ignition do not hold hands, and use well isolated nippers. Ask the assistant to start the engine. If the spark does not slip, define malfunction being guided by the Head an engine Electric equipment. The engine is not turned at attempts of its start
The engine is turned, but not started
