System of onboard diagnostics (OBD) – 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). 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 gets especially importance. 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 million Ohm). As the voltmeter is connected to a checked chain in parallel, accuracy of measurement by that is higher, than the smaller parasitic current will pass through actually device. This problem is not essential at measurement of rather high values of tension (9÷12 In), however becomes vital at diagnostics of elements giving out low-voltage signals, such, as, for example, the oxygen sensor where it is a question of measurement of shares of volt.

The most convenient device for diagnostics of control systems by the engine of modern models of cars are manual input readers of skanerny type (see an illustration below). Scanners of the first generation serve for reading of codes of malfunctions of OBD-I systems. Before application the input reader should be checked on compliance of model and year of release of the checked car. Some scanners are multipurpose, at the expense of possibility of change of a cartridge depending on model of the diagnosed car (Ford, GM, Chrysler, etc.), others are adhered to requirements of the regional authorities and intended for use in certain regions of the world (Europe, Asia, the USA etc.).

With introduction in production meeting the requirements of the last legislations on environmental protection of system of onboard diagnostics of new generation (OBD-II) input readers of a special design started to be issued. Some producers adjusted release of the scanners intended for use by amateur mechanics in house conditions – ask in shops of automobile accessories.

General description of OBD system

Models 1994 and 1995 of вып. are completed with system of onboard diagnostics of the first generation. Since 1996, the Honda Motors company adjusted release of the models equipped with systems of self-diagnostics of the second generation, CARB answering to norms and ERA and received the name OBD-II. The structure of system includes some diagnostic devices making monitoring of separate parameters of systems of decrease in toxicity and fixing revealed refusals in memory of the processor in the form of individual codes of malfunctions. The system makes also check of sensors and actuation mechanisms, supervises operational cycles of a vehicle, provides possibility of freezing of parameters and cleaning of the block of memory.

Data read-out of memory of the OBD-II processor is made by means of the special scanner connected to the 16-contact diagnostic socket of reading of a database (DLC), located under the dashboard from the driver's party of the car. All models of cars of considered brands, since 1996 вып. are equipped with system of self-diagnostics of the second generation of OBD-II. A basic element of system is the onboard processor called by the electronic module of management (ESM), or the module of management in capacity (RSM).

ESM/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, ESM/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.

On service of components of a control system of engine/decrease in toxicity of the fulfilled gases special guarantee certificates with the prolonged validity period extend. It is not necessary to undertake attempts of independent performance of problem diagnostics ESM/RSM or replacement of components of system, to an exit of terms of guarantee certificates, – address to experts firm Honda company service center.

Information sensors

Warmed-up oxygen sensors (HO2S) – the Sensor develops a signal which amplitude depends on the content of oxygen in the fulfilled gases of the engine and external air.

The sensor of provision of a cranked shaft (SKR) - the Sensor is used in systems of self-diagnostics of the first generation (OBD-I) and informs ESM/RSM on the provision of a cranked shaft and engine turns.

The sensor of VMT/provision of cranked shaft/position of the piston (TDC/CKP/CYP) – This sensor is applied in systems of the second generation of OBD-II. On the basis of the analysis of information ESM/RSM arriving from the sensor defines position of the piston of the first cylinder, defines the moments of injection of fuel and ignition.

The sensor of fluctuations of a cranked shaft (CKF) – the Sensor traces changes in frequency of rotation of a cranked shaft. If change of turns of the engine falls outside the limits an admissible range, on ESM/RSM the corresponding signal regarded by the module as the certificate of the admission of ignition stands out.

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 correction 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) – ESM/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 signal ESM/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 changes of pressure in the inlet pipeline, connected with changes of turns and loads of the engine, transforming received information to a peak signal. ESM/RSM uses information delivered by the sensor at corrections of supply of fuel and installations of a corner of an advancing of ignition. The range of change of a target signal of the sensor makes from 1.0÷1.5 In at the closed butterfly valve (deep depression), to 4.0÷4.5 In at completely open zaslonka (low depression). The sensor is located also on the throttle case.

The sensor of speed of movement of the car (VSS) – As appears from its name, informs the sensor ESM/RSM on the current speed of movement of the car.

The pressure sensor in a fuel tank - the Sensor is a compound component of system of catching of fuel evaporations (EVAP) and serves for pressure tracking паров gasoline in a tank. On the basis of information ESM/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 ESM/RSM arriving from the 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.

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

Transmission sensors – In addition to VSS data ESM/RSM receives also information from sensors placed in a transmission, or connected to it. Number of such sensors treat: the sensor of turns of a shaft of the turbine, the sensor of temperature of ATF and the sensor of the chosen transfer.

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 ESM/RSM which regards it as the certificate of increase of load of the engine and as appropriate corrects turns of its single course.

Actuation mechanisms

The main PGM-FI relay (the relay of the fuel pump) – ESM/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. The relay is in the assembly block of distribution of a food in an impellent compartment of the car. The description of procedures of check and replacement of the fuel pump is provided in Head of the Power supply system and release.

Injectors of injection of fuel – ESM/RSM are provided by individual inclusion of each of injectors according to ignition order. Besides, the module supervises duration of opening of the injectors, the defined width of an operating impulse. The amount of fuel injected into the cylinder is defined by duration of opening of an injector. More detailed information on a principle of functioning of system of injection, replacement and service of injectors is provided in Head of the Power supply system and release.

The module of management of ignition (ICM) – the Module operates functioning of coils of ignition, defining demanded a base advancing on the basis of developed ESM/RSM 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 engine Electric equipment.

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 operates ESM/RSM. More detailed information on the IAC valve contains in Chapter 4.

The valve of a purge of a coal adsorber – the Electromagnetic valve of a purge of a coal adsorber is a component of system of catching of fuel evaporations (EVAP) and, working at the command of ESM/RSM, carries out blowing 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.

Reading of codes of malfunctions

 PERFORMANCE ORDER

1. The control service socket is located under the dashboard from the passenger party of the car (see an accompanying illustration).

2. For reading of codes of malfunctions it is necessary to close socket plugs a wire crossing point and to watch indications built in in an instrument guard of the car of a control lamp “Check the engine” (fairly for all models). The special diagnostic input reader can be connected only to the 16-contact diagnostic socket of a database (DLC) located at the left under the dashboard of the car (see an accompanying illustration).

3. For viewing of the codes of malfunctions written down in memory ESM/RSM establish a crossing point in the control service socket (see an illustration to paragraph 1), then include ignition, having turned a key in the situation ON. 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 an instrument guard of the car. The first figure of a two-place code is highlighted by long blinkings of the lamp, the second – short (for example, one long inclusion accompanied six short, corresponds to a code 16).

If in memory of the module of management it is written down more than one code, they will be serially highlighted, then, after a pause the highlighting of codes will repeat.

Cleaning of memory ESM/RSM

When entering a code of malfunction in memory ESM/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 until a food will not be disconnected from it. For cleaning of memory of the module of management on 10÷15 seconds take BACK-UP safety lock from the assembly block located in the right part of an impellent compartment (see. Head Onboard electric equipment).

Extraction of a safety lock will lead also to shutdown of a radio receiver and deleting of its settings.
