21. System of onboard diagnostics - a principle of functioning and codes of malfunctions

Data on diagnostic devices

Check of serviceability of functioning of components of systems of injection and decrease in toxicity of the fulfilled gases is made by means of a universal digital measuring instrument (multimeter) (see an illustration below). Use of a digital measuring instrument preferably for several reasons. First, on analog devices it is rather difficult (sometimes, it is impossible), to define result of the indication to within the 100-th and thousand shares while at inspection of the contours including in the structure electronic components, such accuracy takes on special significance. The second, the reason that fact is not less important that the internal contour of a digital multimeter, has rather high impedance (internal resistance of the device makes 10 megohms). As the voltmeter is connected to a checked chain in parallel, accuracy of measurement by that is higher, than the smaller current will pass through actually device. This factor is not essential at measurement of rather high values of tension (9÷12 In), however there is defining at diagnostics of elements giving out low-voltage signals, such, as, for example, a lambda probe where it is a question of measurement of shares of volt.

Parallel supervision of parameters of signals, resistance and tension in all chains of management is possible by means of a splitter included consistently in the socket of the control unit by the engine. Thus on the switched-off, working engine or during car movement, measurement of parameters of signals on splitter plugs from what the conclusion about possible defects is drawn is made.

Use at diagnostics of considered systems of a digital multimeter with a high impedance essentially increases accuracy of made measurements

Special diagnostic scanners or BMW DIS, MoDIC testers can be applied to diagnostics of electronic systems of the engine, automatic transmission, ABS, SRS (programmed from PC). Besides, it is possible to apply scanners and specialized diagnostic analyzers to this purpose, for example CS 1000, Bosch FSA 560, KTS 300 (HAMMER), Sun 2013, or the ordinary personal computer with the special adapter, a cable and the established program OBD browser (for example, the Bosch ESI program [tronic] in Russian, the Car Scanner program.

The universal K-L-line adapter, serves for coordination of signals of RS-232 port and ISO-9141 (K-line) and ALDL interfaces. The various cables necessary for diagnostics of concrete make of the car can be connected to sockets of the adapter. The switches established in the adapter and elements of indication allow to choose necessary operating modes and approximately to estimate work of target lines. So, the luminescence of a green light-emitting diode with L-line marking, testifies to connection of the line L with the car case. The luminescence of a red light-emitting diode with marking of K-line indicates high potential which blinking of indicators is present during this moment on K.Pri's lines of the established communication with the car can be imperceptible for an eye because of high speed of an exchange. Connection to the computer is made directly to the 25-contact COM port or with the help "RS-232 25 cable Kont. - 9 Kont." in a 9-contact CATFISH port.

Some scanners, besides usual operations of diagnostics, allow, at connection with the personal computer, to unpack being stored in memory of the control unit schematic diagrams of electric equipment (if are put), to program anticreeping system, to observe signals in car chains in real time.

For diagnostics of your car you can download the free version of a browser of OBD II also from a site www.arus.spb.ru.

Manual scanners MoDIC, KTS 300 (Bosch) or the personal computer can be applied to diagnostics of electronic control by systems of the car.

General description of system of self-diagnostics of OBD

The structure of OBD system includes some diagnostic devices making monitoring of separate parameters of systems of decrease in toxicity and fixing revealed refusals in memory of the onboard processor in the form of individual codes of malfunctions. The system makes also check of sensors and actuation mechanisms, supervises vehicle service cycles, provides storing possibility even failures quickly arising in the course of work and cleaning of the block of memory.

Some from models described in the real Management are equipped with system of onboard diagnostics. A basic element of system is the onboard processor more often called by the electronic module of management (ESM), or the module of management of functioning of the power unit (RSM). RSM is a brain of a control system of the engine. Basic data arrive on the module from various information sensors and other electronic components (switches, the relay etc.).

On the basis of the analysis of data arriving from information sensors, and according to put in memory of the processor in base parameters, RSM develops commands for operation of various operating relays and actuation mechanisms, carrying out thereby adjustment of working parameters of the engine and providing maximum efficiency of its return at the minimum fuel consumption.

Data read-out of memory of the OBD processor is made by means of the special scanner connected to the 20-contact diagnostic socket, located at the left in an impellent compartment.

The black, 20-contact diagnostic socket X 1532 is located in the left back part of an impellent compartment, to the right of a dome of an amortization rack (shooter). The M30 engine is shown

D100 — the Diagnostic socket
X20 - the 20-contact SW socket
X85 - the 3-contact SW socket
X122 - the 2-contact SW socket
X1532 - the 20-contact SW socket
X910 - the Connector

In principle, reading written down in memory of system of self-diagnostics of codes of malfunctions can be made by means of a lamp "Check the engine" (address to the Section Reading of codes of malfunctions).

Information sensors

Oxygen sensors (lambda probes) - the Sensor develops a signal which amplitude depends on a difference of the content of oxygen (О2) in the fulfilled gases of the engine and external air before and after the catalytic converter.

The sensor of provision of a cranked shaft (SKR) - the Sensor informs RSM on the provision of a cranked shaft and engine turns. This information is used by the processor at definition of the moments of injection of fuel and installation of a corner of an advancing of ignition.

The sensor of position of pistons (CYP) - on the basis of the analysis of signals of RSM arriving from the sensor calculates position of the piston of the first cylinder and uses this information at definition of the moments and sequence of injection of fuel in chambers of combustion of the engine.

(TDC) VMT sensor - signals Developed by the sensor are used by RSM at definition of installations of a corner of an advancing of ignition at the moment of engine start.

The sensor of temperature of cooling liquid of the engine (eats) - on the basis of information ESM/RSM arriving from the sensor carries out necessary corrections of structure of an air and fuel mix and a corner of an advancing of ignition, and also supervises EGR system work.

The sensor of temperature of soaked-up air (IAT) - RSM uses information arriving from the IAT sensor at corrections of a stream of fuel, installations of a corner of an advancing of ignition and management of EGR system functioning.

The sensor of provision of a butterfly valve (TPS) - the Sensor is located on the case of a throttle and connected to a butterfly valve axis. By amplitude of given-out TPS of a signal of RSM determines a corner of opening of a butterfly valve (copes the driver from a gas pedal) and as appropriate corrects supply of fuel to inlet ports of chambers of combustion. Failure of the sensor, or weakening of its fastening leads to interruptions of injection and violations of stability of turns of idling.

The sensor of absolute pressure in the pipeline (MAR) - the Sensor supervises variations of depth of depression in the inlet pipeline, connected with changes of turns of a cranked shaft and load of the engine and will transform received information to a peak signal. RSM uses information delivered by MAR and IAT sensors at thin corrections of supply of fuel.

The sensor of atmospheric pressure - the Sensor develops the peak signal proportional to changes of atmospheric pressure which is used by RSM at determination of duration of the moments of injection of fuel. The sensor is built in the RSM module and to service in an individual order is not subject.

The detonation sensor - the Sensor reacts to change of level of the vibrations connected with detonations in the engine. On the basis of information of RSM arriving from the sensor carries out the corresponding correction of a corner of an advancing of ignition.

The sensor of speed of movement of the car (VSS) - As appears from its name, the sensor informs the processor on the current speed of movement of the car.

The sensor of size of opening of the EGR valve - the Sensor notifies RSM on size of shift of a plunzher of the EGR valve. Received information is used then the processor at management of functioning of system of a retsirkulyatsiya of the fulfilled gases.

The pressure sensor in a fuel tank - the Sensor is a component of system of catching of fuel evaporations (EVAP) and serves for pressure tracking паров gasoline in a tank. On the basis of information of RSM arriving from the sensor gives out commands for operation of electromagnetic valves of a purge of system.

The sensor switch of pressure of system of hydrostrengthening of a wheel (PSP) - on the basis of information of RSM arriving from the PSP sensor switch provides increase of turns of idling at the expense of IAC sensor operation for the purpose of compensation of increasing loads of the engine, connected with functioning of the steering hydraulic booster at commission of maneuvers.

Transmission sensors - In addition to the data arriving from VSS, RSM receives also information from the sensors placed in a transmission, or connected to it. Number of such sensors treat: (а) sensor of turns of a secondary (radical) shaft and (b) sensor of turns of an intermediate shaft.

The sensor switch of management of turning on of the coupling of coupling of the conditioner of air - When giving food from the battery to the electromagnetic valve of the To/to compressor the corresponding information signal arrives on RSM which regards it as the certificate of increase of load of the engine and as appropriate corrects turns of its idling.

Actuation mechanisms

The main PGM-FI relay (the relay of the fuel pump) - RSM makes activation of the relay of the fuel pump at an ignition key povorachivaniye in the situation START or RUN. At ignition inclusion activation of the relay provides pressure lifting in a power supply system. More detailed information on the main relay is provided in Head the Power supply system.

Fuel injectors - RSM provides individual inclusion of each of injectors according to an ignition established order. Besides, the module supervises duration of opening of the injectors, defined in the width of an operating impulse measured in milliseconds and defining amount of fuel injected into the cylinder. More detailed information on a principle of functioning of system of injection, replacement and service of injectors is provided in Head the Power supply system.

The module of management of ignition (ICM) - the Module operates functioning of the coil of ignition, defining a demanded base advancing on the basis of developed RSM of teams. On all models of cars considered in the real Management it is used built in the distributor of ignition of ICM, for more details see. Head ignition System.

The valve of stabilization of turns of idling (IAC) - the IAC Valve carries out a dosage of amount of the air which is restarted up bypassing a butterfly valve when the last is closed, or occupies the provision of idling. Opening of the valve and formation of a rezultiruyushchy air stream RSM operates.

The electromagnetic valve of a purge of a coal adsorber - the Valve is a component of system of catching of fuel evaporations (EVAP) and, working at the command of RSM, carries out release accumulated in an adsorber паров fuels in the inlet pipeline for the purpose of burning them in the course of normal functioning of the engine.

The electromagnet of management of a purge of a coal adsorber - the Electromagnet is used by RSM at check by OBD-II system of serviceability of functioning of EVAP system.

Reading of codes of malfunctions

At detection of the malfunction repeating in a row on two trips, RSM gives out command for inclusion of the control lamp built in in an instrument guard "Check the engine", called also the indicator of refusals. The lamp will continue to burn until memory of system of self-diagnostics will not be cleared of the codes of the revealed malfunctions brought in it. Reading of codes of malfunctions in OBD system can be made in the various ways. The main way is reading by means of described above the devices connected to the DLC socket of OBD system. Other ways are possible not on all models. The blinking code can be считан on a lamp "Check the engine".

Without starting the engine, include ignition - a control lamp "Check the engine" should light up, otherwise it is necessary to replace it.

On early models, in the presence of malfunctions, the control lamp several times will flash on 1 second and will go out, before will light up constantly. The number of flashes of a lamp (from 1 to 4) corresponds to a malfunction code (the list lower).

Method of reading of blinking codes by a lamp "Check the engine" (it is possible on some models)

The chart of delivery of a blinking code a control lamp

Include ignition. Five times within five seconds completely squeeze out and release an accelerator pedal. If in memory of the processor codes of taking place malfunctions are brought, they will start to be highlighted consistently by a control lamp "Check the engine" on a control panel of the car. Consider a blinking code.

The lamp lights up on 5 seconds, in 0.5 seconds again lights up on 2.5 seconds, and through an interval of 2.5 seconds the code stands out. Value of each category of a code corresponds to number of flashes with an interval of 0.5 seconds. The senior categories of a code, the last – units at first stand out. Intervals between code categories - 2.5 seconds. After code delivery a lamp it is necessary to burn. Repeat procedure to consider the subsequent codes. If the first given-out code 1444, 2444 or 4444 - malfunctions are not fixed.

The codes 1000 or 2000 which are given out by one or two flashes and a long pause, and then continuous burning of a lamp, indicate the completion of delivery of a code.

Engine start automatically interrupts access to diagnostics system.

Cleaning of memory of OBD

When entering a code of malfunction in memory of RSM on an instrument guard of the car the control lamp "Lights up check the engine". The code remains written down in memory of the module.

For cleaning of memory of ESM connect to system the scanner and choose in its menu the CLEARING COEDS function (Removal of codes). Further follow the instructions highlighted on the device, or at once for 30 seconds take from the nest in the assembly block EFI safety lock.

Alternatively cleaning of memory of system can be made by a way of removal of a fusible insert (the main safety lock of system of onboard power supply), the battery established near the positive plug (it is possible to disconnect also simply from the battery a positive wire).

It is necessary to mean that when cleaning memory of OBD by a detachment of a negative wire from the battery, adjusting parameters of the engine are erased and stability of its turns for short time after primary start is broken.


If the stereosystem established on the car is equipped with a security code before disconnecting the battery, make sure that have the correct combination for audiosystem input in action!


Battery shutdown also leads to removal of settings of the receiver on favourite radio stations.


In order to avoid ESM damage its shutdown and connection should be made only at the switched-off ignition!

Track, that memory of system was cleared before installation on the engine of new components of systems of decrease in toxicity of the fulfilled gases. If before system start after replacement of the failed information sensor not to make cleaning of memory of refusals, RSM will bring in it a new code of malfunction. Cleaning of memory allows the processor to make change-over on new parameters. Thus, the first 50 ÷ 20 minutes after primary start of the engine, some violation of stability of its turns can take place.
