By 1968 regulations , were introduced in California by Californian State Government under the "Clean Air Act" to restrict pollutant emissions for passenger cars. , , , , A , The objective of the Self-Diagnosis (SD) function (sometimes termed On-Board Diagnosis or OBD) is to minimise pollutant emissions for motor vehicles. Self-diagnosis is the basis for controlling engine performance in order to provlde the most effective conditions for efficient operation. Dioxide Perfect combustion Heynes Engine Management Techbook A general knowledge of engine management system (EMS) operation and of the chemical sequences of combustion for internal combustion engines will help explain why and how SD has become such an important part of the modern vehicle. Refer to the companion volume "Automotive Engine Management and Fuel Injection Systems Manual" (Book No 3344, available from the publishers of this title) for a description of the operation of the modern EMS. Water Hydrocarbons The chemical sequence of combustion Fuels for spark ignition and diesel engines consist of various hydrocarbon compounds, which combine with the oxygen of the intake air. Nitrogen and other residual gases also combine during the combustion process. With perfect cordbustion, no toxic substances would be produced. Under actual operating conditions, non-toxic exhaust gases such as nitrogen (N,), water vapour (H,O) and carbon dioxide (CO,) join the toxic products of incomplete combustion. Toxic substances in exhaust gases include carbon monoxide (CO), partially-unbumt hydrocarbons (HC), nitrogen oxides, sulphur dioxide (SO,), lead compounds and soot (see illustrations 1.1 and 1.2). The high concentratlon of pollutants resulting from vehicle emissions are known to be causing health problems, notably respiratory illnesses, and also have environmentally-damaging effects. The idea that toxic emissions should be reduced while maintaining or improving the lncomplete combustion Water Hydrocarbons tiWM 1.1 Combustion chart 112 Introduction to Self-Diagnosis Pollutants 1.0 Water Vapour 12.7 Argon and Oxygen 0.7- Dioxide 12.1 HZ9688 - ' I d 1.2 Pollutant chart showing the percentage of toxic smlssions in 1.OW of exhaust gas 1.3 18-pin Self-Diagnosis connector Confrol functions, monitoring and dlagnosflc communicafion A brief definition of SeM-Diagnosis (SDl By 1978 the first Engine Management Systems were developed, f~rstappearing as the Bosch Motron~cwhich was fitted to the BMW 7321. Englne management serves the purpose of enabling the engine components to operate effectively by means of an Etectron~c Cantrot Module (ECM) which controls, monitors and in some cases adapts to ensure that tha most efficient levels of engine operation can be expected. The EMS soon evolved to include a SelfDiagnosis (SD)function whlch not only controls and monitors components of the engine system but alsa enables the driver or t e c h n c ~ ato~ identify faults that are otherwise difficult to detect. This was achieved by the invention and application of a data communication system, and the introduction of a computertsed memory into the ECM. Faults could then be stored in ECM memory and retrieved at a latsr time. On some models, a self-diagnostic warning light illuminates to give warning of a fault, or the tight can be used to display the stored faults as a series of flashes. A 1981 Caditlac was the first vehicle to which an ECM with self-diagnosis was fitted, and the system was Bendix Digital. Since the early 1980s, the evolution of the EMS has been relatively quick, and most vehicle manufacturers now equip their vehicles with an EMS that only bears some 5maU resemblance to the early systems. Not only are the most recent Engine Management Systems almost universally fitted with a selfdiagnosis capability, but many automatic transmissions, anti-lock brak~ng systems (ABS) and supplementary restraint systems (SRS, typically airbags) controlled by ECMs have self-dragnosis. An adaptive capability has been ~ntroduced so that component operation is cont~nually monitored and adjusted for optimum performance. The Self-Diagnosis tunction checks tho signals from the ECM circuits against a set of control parameters. If a signal does not lie with~nthe bounds of the control parameters, an lnternal fault rs stored In ECM memory. The stored faults are represented in the main by codes termed "Fault Codes". When the fault codes are retrieved from the ECM they become an invaluable aid to diagnosis. Standardisation of On-Board Diagnosis (OBDJ On-board Diagnosis established three essent~al criteria for manufacturers and vehicle technicians/eng~neersto ensure that vehicles contorm from model year 1988. First, vehicles must be eau~ppedwith an electronjc SD system. Second, any faults (malfunctions) relevant to exhaust emissions must be djsplayed by means of an SO warning light installed on the instrument panel. Third, the fault must be recorded in ECM fault memory, and may be retrievable with the aid of a Fault Code Reader (FCR), or via Flash Codes. From 1988 to 1991 the International Standards Orgarusation drafted and updated 150 9141 to IS09141-2, which attempts to standardise: The SD plug connection. The diagnostic equipment and its range of diagnoses. The contents of the protocols. The extent of data lo be exchanged, These were based on the regulations for America. However, these agreed requirements are now being adopted by European governmer.ts and governments of all five continents in consultation with veh~clemanufacturers. More requirements were laid down by a second regulation, 060 11, whlch was applied from model year 1994. Diesel engines were also subject to the OSO requirements as of model year 1996. The additional requirements are as follows: Additional flashing function of the SD warning light. Monitoring of functions and components, not only for defects,but also for ensuring adherence to emission vafues. In addition to storing faults as a digital code, the operating conditions are also stored in the so-called "Freeze Frame". The contents of the fault memory must be capable of being retrieved by a Fault C d e Reader instead of fiash Codes. Note: Systems designed fo OED /I are equipped with a 16-pin SD connector (see iIIustrution 1.3). The monrtoring funct~on of engtne management systems has also been extended and regulated. OBD I1 calls for the cantinuo~~smonitoring of the following components and areas: Combustion. Catalytic convemr. Oxygen sensor. Secondary air system. Fuel evaporation system. Exhaust-gas recirculation (EGR) system. Diesel englnes are subject to the same regulations and objectives, but obviously different components, such as glow plugs, are monitored to interact with the relevant technology employed on each system. The ISO, the SAE and a plethora of transport and environmentally-concernednongovernmental organisations have argued for further and consistent regulations. The US "Clean Air Acts" have adopted the CAR8 standards as a mmirnurn level of protection for pudic health and welkbeing; similar legbslation has been brought into be~ngby many local snd national governments since 1968. The Introduction of catatytic converters. fuel injection systems, the increased use of vehicle diesel engines and of unleaded petrol engines during the past 30 years, has made further positive contributions to reducing the problems which arise with pollutant emissions. lntmduction to Self-Diagnosis 103 Eumpean On-Board Diagnosis IEOW European vehicle manufacturers await the introduction of a European On-Board Oiagnosis (EOBD) def~nit~on,which will strengthen the IS0 914 t -CARB definition, and that Is expected to be introduced by the 2000 millennium. A Europe-wide worktng party is in axistence to determine the details of the EOBD standards. EOBD is likely to include rimy of the OBD II conditions, but additional rnasures are also being considered. m~Ktureproblems and the probable number of different codes that could be generated. As the EMS evolves, many more cornwnen:s will be controlled and monitored by the ECM, and the SD function w~llcertainly extend to cover these additional components. Th~sbook is mainly concerned with testing areas that relate to the engine, although all codes generated by ancillary systems such as the air conditioning and automatic transmission wilt be listed in the Fault Code tables appearing In each Chapter. Urnitations to Self-Diagmsis hfl-Diagnosis function The Self-bagnosis (SD) function (sometimes termed On-Board Diagnosis or OBO) of the modern Engine Management System continualty exarnlnes the signal values from the various engine sensors and actuators. The signals are then cornpard wilh pre-programmed control parameters. The control parameters may vary from system to system, and could include upper and lower measurement values, a speciftc number of woneous signals within a pre-determined tlme period, implaus~blesignals, signals outs~de of adaptwe limits, and other parameters determined by the system dtrsigner or vehicle manufacturer. If the signal value IS outside of the conlrol parameters (for example a short-circuit or an open-circuit), the ECM determines that a fault is present, and stores a coda In ECM fault memorj. Early SO systarns were capable of generating and storing no more than a handful of cMes. However, 10 years on, many of the more advanced systems can generate 100 or mwe codes, and this may sharply increase over the next decade as snglne management becomes capable of diagnosing many more fault conditions. For exarnpk, in one SD system, a s;mple d e may be generated to cover a!l possible fault conditions that could affect a particular crrcuit. in anotper SD system, several codes may be generated to cover various fault conditions, and this could pinpoint the reason fw the tault in that part~cularsensor. Ifwe use the Coolent Temperature Sensor {CTS) circuit as an example, the first code may be generated as a general CTS tault. Other ccdes may be generated to indicate an open or short-circuit. In additinn, codes that indicate a weak or a rich m~nturecondition may be generated as a consequence of thls particular component failure. Where the ECM practises adaplive control around the ideal mixture ratio, a fault may cause the adaptive limlts to be exceeded, and even more codes may be raised. However. on determination of such a fault, the EMS will certainly move into LOS or "limp-home" mode - this will reduce the There are some limitations to SelfDiagnosu, and some sensor faults may not necessarily cause a code to be stored. Faults in components for which a code is not available or for conditions not covered by the d~agnosticsoftware wlll not be stored. This also means that mechanical problems and secondarj ignition circuit (HT)faults are not directly covered by the SD system. However, side-eHecls from, for example, a vacuum leak or faulty exhaust valve will create mixture and idle problems, which may cause appropriate codes to be stored. The tnck then is to relate the fault code to the engine condrtion - engine checks may I% necessary to aid diagnosis in this respect. In addition, a fault code generally only points to a faulty circuit. For example, a code il?dicating a CTS fault may be caused by a faulty coolant temperature sensor, a wiring fault or a corroded connector. Some vehicle systems are capable of storing faults that occur intermittently - others are not. In some instan-, a fault code may be lost the moment that the ignition is switched off; care should be taken when retrieving codes or investigatingfaults in this kind of system. The smart technician will use the fault code as a starting point, and as such, it can cluicklv . . point hlrn the right direction. On the other hand, absence of a code may not always be indicative af a fault-free system, and care shoubd be exercised during diagnosis. in Spurious signal Faulty HT s~gnals or faulty electrbcal componerlts can create Radio Frequency Interference (RFI) that may disrupt the EMS or cause spurious (erroneous) codes to be generated. A disrupted EMS may result In erratic ECM ooeration. Umited range or out-of-range sensors If the sensor remains wi?hin its design parameters,even if the permeters are incorrect for certa[n operating conddions, a fault o d e will not be stored. For example, a faulty coolanl t'emp6mture sensw will cause a fauk code to be qeneratnd if it is open-circuit or shorted to earth. However, if the sensor resistance does not change during a temperature change, a code may not be generated, although the engine will Indeed run badly at some temperatures. 'The majority of current SD systems would not recognise a fault m this instance because the signal would remain within the control parameters. The next paragraph describes poss~ble methods of overcoming this particular problem. lmalausible sicmals The software in some newer systams IS becoming more sophisticated, and may check for a change in vokage or current over a period oi tlrne. If the s i g n ~output l does not change as expected, a fault wrH be stored. Also, earlier systems would generate a fault code if a particular circhlt was outside of the control parameters without reference to other data or circuits. More modern systems may consider ths output from several components, and relate one s~gnalto another. A fault code may be generated based upon the plausibilrty of the signal when related to a number of other signals. For instance,if me engine speed mPM) is increasing, the throttle position sensor (TPS) indicates a wide-open throttle, yet the airflow sensor (AFS) does not indicate an increase in airflow, the AFS signal could be considered implausible and a c d e would be generatd. Many vehicles are equipped with an SD warning light, usually located in the instrument panel on the facia (see lllustretions 1.4 to I.0). Alternatively, an LED may be set into the casing of the ECM. Onoe the ignition is turned on, the warning light or LED will illuminate. 1.4 A typical SD wemino light located In the insbment panel 1e 4 Introduction to Self-Diagnosis retr~evai routine. Although manual coae retnevlng (described below) rs possible In most early systems, the practice IS dy~ngout; mcst modern systems allow retr~eva\via an FCR alone. FCR or Scanner ? 1.5 A second typical SD warning light located in the instrument panel This serves as a check that the light circu~l4s functional After the engine has started, the light should ext!ngulsh and remaan off so long as the SD system does not detect a fault. If the ECM detemlnes that a detectable fault is present, the warning light IS turned on. The light remains turned on until the detectable fault is no longer present. If the fault clears, the light will usua\!y turn off, allhough the code itself may remaln stored until the ECM fault memory is cleared. A fault in some systems may tJe classified as a minor fault and although the ECM will log the presence of the fault, the light may not be turned on. Not all vehicles utihse a warning light: systems w~thoutone will require interrogation by a FCR or Flash Code d~splayby manual means to detenn~newhether a fault 1s stored or nclt. Fast and slow codes Codes transmitted by an ECM may be designated as "slow codes" or "last codes". Slow codes are fault codes wh~chare emrtted slowly enough to be displayed on an LED or on a facia-mounted warning light. Fast codes are digital fault codes that are too fast to be oisplayed on the LEO or on the warning light. A d~gltal FCR instrument is required for captur~ngtast codes. 1.6 Typical appearance for a SD warning light Other SD functions To a large degree. the format ar,d type of dala to be output is determined by the vehlcle manufacturer (VM). The fuvction of the FCR or manual code extraction routlne is to initlate the VM's program and to make the best of what is actually ava~lable.In other words, if the VM does not make certa~nlnforrnat~on available, then it is not possible to access such information through the serial port. In addition to code retrieval and code clearing, a number of other functions are often available through SD,as l~stedbelow: Code retrieval. Code clearing. Actuator and component testlng. Service adjustments. ECM coding. Obtaining Datastream. Flight recorder function. Note: Not all of the above functions are available in all systems, and an FCR will be necessary for many of the more advanced functions. Fault code mtrieval Fault codes can be retneved from the ECM via an SD output termrna! (sometimes known as a Ser~alPort), by connecting a suitable Fault Code Reader or by trigger:ng a manual The professional tool used for retrieving codes from SD systems on motor veh~clesin the UK is termed a Fault Code Reader. However another term sometimes used IS "Scanner". The "Scanner" term originated in the USA, and defrnes a tool that "scans" data, as dlstinct from a tool whose sole function 1s to "rel:~eve" data. Real~stically.the terms can be used interchangeably to descrlbe coderetrieving equ~pment.Generally, we will use the term FCR to descr~bethe code-reading equlprnent covered by this book. Manual fault code retrieval ("Flash Codes") Some of the early SD systems allowed ~naoualcode retrieval. Although qulte useful as a "quick-and-dirty" method of accessing codes without sophisilcated equipment, manual code retrieval is Irrn~ted,slow and prone to error. In addition, it is not possrble to retneve codes that are transmitted at Ine h~gh trar~sfer rates seen In modern syslems. Typically, manual code relrieval is initiated by using a jumper lead to br~dgecertain terminals III the SD connector. The codes are then displayed by the flashng of the Instrument panel warning light, or on :he LED set into the ECM casing (where these components are fittd). Codes oLtained in th~sfashon are often ternled "Flash Codes" (see iltustrations 1.7 to 1.9). By counting the flashes or meter sweeps and referr~ngto the Fault Code table in earn Chapter, faults can thus be detennined. Where an SD light or LED is not fitted, an 1-ED diode or a voltmeter (see Warning No 5 in the Reference Section at the end of this book) can be used In some systems. Fault code clearing There are a number of methods used by the vehicle manufacturers to clear fault memory over the years. Mid-198Ds systems d ~ d not 1 second flashos Short pause retain codes, and were aulornalically cleared once the ignttron was t~rrnedoff. Soon the 1.5 second pause ECM fault memory was provided with a between codes permanent battery voltage that allowed codes and other data to be retained aRer the ignrtion was turned off Codes generated b y these systems are normally cleared with an FCR (preferred method), altnough a manual routine is often possible. Removing a battery lead or the ECM multi-plug may also clear the codes from memory. Some of the lalest types of systems utflise non-volatile memory Nonvolatile memory retarns data even afler the battery has been d~sconnected,and code clearing must be effected w ~ t hthe a~clof an FCR {seeilluslration 1.19).

Multiples of 10 indicated by Units indicated Actuator and component testing The FCR can be used to test the wiring and components In certain actuator circu~ts.For example, the idle speed control valve (ISCV) circult could be energlsed. If the valve actuates, this proves the Integrity of that circuit. Depending on the system (it is not possible to test a particular actuator unless the routine has been designed into the SD system), possible circuits include the fuel Injectors, relays. ISCV, and emission actuators amongst others. It may also be possrble to test the signals from certain sensors. A common test IS to check the signal from the throttle posltlor~sensor (TPS) as the throttle IS moved from the closed to the fully-open position and then returned to the closed position. Afault will be reg~stered~f the potentlometer track 1s deemed to be defective. 1 3 2 2 (Example of codes 12 and 32) HA 1.8 Representation of typical 2-digit flash codes as displayed on an SD warning light or LED.

However, in a very few systerns, rrlanual actuation a r ~ dcomponent testlng is possible. Where appropriate, these rout~neswill be described In the relevant Chapter. Service adjustments In most modern engines. any kind of adlustment to the Idle mixture or ignition tlmlng 1s not poss~ble.However, some older systems are denied external adjustment, and an FCR is essential if certain adjustments are to be effected. Examples include some Ford vehicles with EEC IV, the Rover 800 SPI, and more recent Rover veh~cleswith MEMS. All of these veh~clesrequire an FCR for varlous adiustments including ignition timing and/or rdle mixture adjustment. 1 2 3 2 (Example of code 1223) 1.9 Representation of typical 4-digit flash codes as displayed on an SD warning light or LED with the engine cold, and closely monitored as the englne IS warmed up.

All of the signals (or a selection) could then be played back and temperatures. For example, the coolant reviewed at some later stage. temperature sensor signal could be viewed 1.10 A common proprietary Fault Code Reader ! 1.6 Introduction to Self-Diagnosis Flight mcorrder function A tacil~tythat is available in some FCRs and/or SD systems is Ihal of a "flight recorder" mode - more usually called a "snapshot" or "playback" function. Where a fault is intermittent or difficult to diagnose, the condition of the various components can be determined from the signal output at the moment of fault occurrence, and this could lead to a solution. The FCR must be attached to the SD connector, and the vehicle taken for a road test. The snapshot function is usually initiated at an early stage in the run. Data will be gathered and recorded during the running period. However, since the memory capacity of the ECM or FCR is limited, data will only be retained for a short period. When the fault occurs, it is necessary to hit a button, then a pre-determined number of records bfore the occunence and after will be stored. Back in the workshop, the data (usually presented as Datastream) can be played back one sample at a time, and frozen for evaluation where requird. Reviewing all of the data from each sensor and actuator may then lead to the solution. However, not all SD systems or even all FCRs are capable of this function. The majority of modern SD systems also have a Limited Operating Strategy (LOS) othewise known as "limp-home" mode. This means that in the event of a fault in certain sensor circuits (and usually where a fault code has b e n generated, although not all codes will initiate LOS), the ECM will automatically enter LOS and refer to a programmed default value rather than the sensor signal. This enables the vehicle to be safely driven to a workshop/ garage for repair or testing. Once the fault has cleared, the ECM will revert to normal operation. LOS is a safety system, which allows the engine to operate at a reduced efficiency level. Some LOS systems are so smart, the driver may be unaware that a fault has occurred unless the warning light is illuminated (if fitted). Since the substituted values is often that of a hot or semi-hot engine, cold starting and running during the warm-up period may be less than satisfactory. Also, failure of a major sensor, such as the airflow sensor or the MAP sensor, may cause the ECM to restrict engine performance. For example, if a Ford EEC IV system detects a major fault within the ECM, the engine will run with the timing set to lo0 (no timing advance) and the fuel pump will run continuously. In some systems, failure of a coolant or air temperature sensor (CTS or ATS) will cause the ECM to use the other component as a default. For example, if the CTS failed, the ECM would use the ATS value. In addition, the default value might be used when the engine is cold and then switched to a value that IS close to that of a hol wnglno after the englne has run for 10 minutes. Unless the SD warnrng light comes on, it would thus be very difficult to recognise that a fault had actually occurred. In many modern engine management systems, the ECM is adaptive to changing engine operating characteristics. Where the ECM software is adaptive, the data is constantly monitored from various engine functions, and the data is stored in memory so that over a fairly long monitoring period, signal averages can be built. During normal engine operation, the ECM refers to several three-dimensional maps for timing, fuel injection, idle speed etc. Depending upon the changing signals from the various sensors (ATS, CTS, AFS or MAP, TPS, etc), the ECM constantly corrects the final output signals to the various actuators. By adopting the stored adaptive values as a correction to the basic map, the ECM is able to adapt much more quickly to almost any changed operating circumstances. As the engine or its components wear or even if certain faults develop, the changed signals are added to the stored adaptive memory, and the signal averages gradually change. The ECM continually reacts to the adaptive memory and soon adapts to the changed conditions. If the adaptive value exceeds the control parameters, a fault code may be generated. Adaptive control is applied typically to the following areas, and adaptation and correction of the various maps usually occurs during idle or part-load engine operation: Idle operation. Mixture adjustment. Knock control. Carbon filter solenoid valve {CFSV) operation. Exhaust gas recirculation (EGR}. When the adaptive map is used in conjunction with the oxygen sensor (0s)in a catalytic converter system, the ECM is able to respond much more quickly and retain tighter control over the changing gases in the exhaust system. During closed-loop operation, the basic injection value Is determined by the vatues stored in the map for a specific rpm and load. If the basic injection value causes exhaust emissions outside of the lambda value (0.98 to 1.02 air-fuel ratio) the mixture would be too rich or too lean, and the OS would signal the ECM which in turn will correct the mixture. However, this response takes a little time, and so the ECM learns a correction value and adds this "adaptive" value to the basic map. From now on, under most operating conditions, the emissions will be very close to Lambda and so, after reference to the OS signal and adaptive map, the ECM wlll only need to make small ; correct~onsto keep ~tthat way. ! At ldle speed, the system w~llsettle down to ; idle at the best speed for each ~ndlv~dua application.

However. the adaptation w ~ lalso if a sudden and dramat~cchange occurs. the adapt~vefunct~onmay take some tlme to readapt to the changed conditions. The change in circumstances can occur when a fault occurs In the system, or even arter a system component has been changed When one or more system components have been renewed, the ECM will need to relearn the new values, and t h ~ s can sometimes create operating problems unt~l the ECM has compleled the process. This can create a temporary veh~cledr~veabil~ty fault that could certatnly occur after proper repairs have been made to some part of the system. The driveabllity faull should gradually become less prominent as the EMS adapts. For example, an injector may be leak~ngand the ECM will adapt to prov~dea leaner mixture Once the faulty injecior has been rwnewed or cleaned, the adaptation w ~ len l towards lean, and the engine may be hesitant until the ECM adapts to the correct m~xture.In some systems. it is possible to use an FCR lo reset Ihe ECM adaptive memorj to the or~ginaldefault value after a mmponent has been renewed. Most adaptive systems w ~ l llose ihwr settings if the battery is d~sconnected.Once the battery is reconnecled and the engrne 1s restarted, the system will need to go through a relearning curve. This usually occurs 7arrly quickly, although idle quality may be poor unt~ the adaptive process is completed. Not all systems are affected by batterj disconnection. Rover MEMS IS an example of a system that uses non-volat~lememory to retain adaptive settings when the battery 1s disconnected. ' : Rogue adaptive function The danger with an adaptive functlon IS lhat sometimes an erroneous signal may be adopted as a valid measurement, and th~smay create an operating problem. If the erroneous signal is not serious enough to generate a fault code, the fault may remain undetected. In some instances the ECM can become confused and the adaptive values could become corrupted. This may cause operational problems, and a system check will reveal "no fault found". Disconnecting the vehicle battery may effect a cure. since therecalibration will reset the ECM default base values. However, resening values with an FCR is the preferred method, to avo~dthe loss of other stored values that w ~ l loccur after disconnection ol the batterj.

To be good at it, you n d to seriously invest in three areas. We can liken ~ to the good old threelegged the t h r areas stool. In our automotive stool, the legs are equipment, training and information. Kick one leg away, and the others are left a little shaky. Those with serious diagnostic intentions will make appropriate investments in all three areas. That is not to say that those without the M t equipment, or the necessary know-how, or the information, are completely stuck. It will just require a little more time and patience, that's all.

The greater the level of investment in equipment and training, the speedier the diagnosis. The less investment, the longer it will take. Obvious, really! Within the confines of this Chapter, we will look at the Fault Code Reader and other equipment suitable for testing the various components of the Engine Management System.
