Automotive Vehicle Strategies and ECM Modes(Diagnostic Strategies of Modern Automotive Systems)By Mandy ConcepcionThis book is divided into two sections, “Vehicle Operational Strategies”, which detail what's needed for and engine to start. In other words, this section concentrates on the signals needed for a particular manufacturer to make the engine run. These signal strategies are true regardless of the system and the section simply zeros in on the actual signal, whether it's a distributor, DIS, COP, etc. The second section is the "ECM operational modes" and goes into details on why and how the ECM does what it needs to do to run the engine. In other words, this section has to do with the behavior of the ECM according to outside conditions.VEHICLE OPERATIONAL STRATEGIESThis section is designed to serve as a functional guide to some of the more difficult to diagnose faults. It basically came about from the trial and error experimentation with different systems, during the diagnostic process. It is not a study section per se, but will definitelyenlighten the technician as to the logics of different systems on the market today. Hopefully, it will serve to pinpoint the source of an actual problem.ECM OPERATIONAL MODES In this section, we'll take a look at automotive OPERATIONAL MODES. The section deals with the specifics of internal ECM programming strategies. The knowledge gained here will aide the modern technician is deciphering why is the ECM functioning in a specific way. This section, as in other parts of this book, helps to answer the technician's diagnostic basic question “What is the ECM seeing, that's causing it to do what it does?”Table of ContentsVEHICLE OPERATIONAL STRATEGIES- HONDA IGNITION & INJECTION STRATEGY- MAZDA IGNITION STRATEGY- MAZDA EEC IV IGNITION STRATEGY- MITSUBISHI/HYUNDAI IGNITION STRATEGY- NISSAN IGNITION STRATEGY- NISSAN COP IGNITION STRATEGY- TOYOTA IGNITION STRATEGYECM OPERATIONAL MODES• CRANKING ENRICHMENT MODE• ENGINE WARM-UP MODE• OPEN-LOOP MODE• CLOSE-LOOP MODE• ACCELERATION ENRICHMENT MODE• DECELERATION ENLEANMENT MODE• IDLE SPEED CONTROL MODE• LOW VOLTAGE CORRECTION MODE• CLEAR FLOOD MODE• SELECTIVE FUEL INJECTOR CUT-OFF MODE• LIMP-HOME MODE• EXHAUST VARIABLE VALVE TIMING/EGR CONTROL MODE

Automotive Scan Tool PID Diagnostics (Diagnostics Strategies of Modern Automotive Systems ) By Mandy Concepcion In this section, the different techniques of scan tool parameter (PID) analysis will be exposed. Techniques involving PID analysis are quickly catching on, due to their speed and accuracy. By properly analyzing the different scanner PIDs, the technician can arrive at the source of the problem much faster and accurately. These procedures give rise to the new term “driver seat diagnostics”, since most of the preliminary diagnostic work is done through the scanner. However, these techniques will in no way replace the final manual tests that are a part of every diagnostic path. They are simply geared to point the technician in the right direction. Table of Contents INTRODUCTION (Introduction to scan tool diagnostics and the relevance of using PIDs or scanner parameter to perform the first leg of all diagnostics.) - Theory of Operation Behind the Different PIDs (Describes CARB, the difference between generic and enhanced PIDs, the FTP) - OBD II Generic PIDs (PID calculated and actual values, calculated data relationships, base injection timing, ECM value substitution) - OBD I & II General PID analysis (erasing code-or not, recording, analyzing and pinpoint tests, separating PIDs into groups) - Fuel Delivery Fault Detection (fuel delivery issues, intake air temp. sensor, BARO sensor, Engine LOAD, RPM PID, Short-Term Fuel Trims, Long-Term Fuel Trims, 60% of check engine light issues, block learn/integrators, Example 1: injector fault, Example 2: intake gasket issues, fuel status, ignition timing, MAP/MAF, TPS, O2 sensor, IAC, Closed Throttle, injector pulse width, voltage power, injector dutycycle, fuel trim cell) - Test #1 (Determining an engine’s fuel Consumption (rich-lean operation, duty-cycle to fuel trim relationship, O2 sensor to fuel trim relation, FT and vacuum leaks, ignition timing and idle control, test conclusion) - Test # 2 (Misfire Detection Strategy, EGR, Ignition and Mechanical misfires) (misfires and OBD2, scanner misfire detection – a time saver, OBD2 40 and 80 cycle misfire, ignition, injector and EGR density misfire, coil-on-plug, misfires and O2 sensor, lean O2 & Secondary misfire, O2 sensor & injector misfires, leaky injector, EGR and the MAP, Type A, B, C misfires, test conclusion) - Test # 3 (Air/Fuel Ratio Faults) (air-fuel imbalance, MAF and post O2 sensors, open-closed-loop, fuel enable, HC & CO relation to AF issues, test conclusion) - Test # 4 (BARO, MAP & MAF PID analysis) (MAP & valve timing faults, ECM behavior, fuel delivery or duty cycle test, volumetric efficiency, , test conclusion) - Test # 5 (Clogged exhaust) (clogged catalytic converter detection, TPS, MAF and converters, idle and WOT or wide open throttle values, vacuum readings, MAP to WOT chats analysis, engine and MAP vacuum, test conclusion) - Test # 6 (EGR Fault Detection) (EGR and MAP values, ECM reaction to EGR issues, EGR temp sensor, DPFE sensor, EGR and O2-MAP and lift position sensor, EGR and engine pre-loading, EGR and the ECM erroneous high LOAD issues, test conclusion) - Test # 7 (O2 Sensor Heater) (O2 heaters and why?, tough to check O2 heater issues, O2 heater effect on signal output, O2 heater bias voltage, engine off and O2 changing value, test conclusion) - Test # 8 (Resetting Fuel Trims) (resetting injection pulse corrections, long-term and short-term fuel trims, learn condition, Lambda, case study on fuel trims, FT resetting according to manufacturer, test conclusion) - Test # 9 (Engine Cranking Vacuum Test) (MAP/MAF cranking vacuum, vacuum to PID analysis, vacuum leaks, gauge-PID test, sources of leaks, cranking values, test conclusion)

Since the early seventies, the development of the automobile has been characterized by a steady increase in the deploymnet of onboard electronics systems and software. This trend continues unabated and is driven by rising end-user demands and increasingly stringent environmental requirements. Today, almost every function onboard the modern vehicle is electronically controlled or monitored. The software-based implementation of vehicle functions provides for unparalleled freedoms of concept and design. However, automobile development calls for the accommodation of contrasting prerequisites – such as higher demands on safety and reliability vs. lower cost ceilings, longer product life cycles vs. shorter development times – along with growing proliferation of model variants. Automotive Software Engineering has established its position at the center of these seemingly conflicting opposites. This book provides background basics as well as numerous suggestions, rare insights, and cases in point concerning those processes, methods, and tools that contribute to the surefooted mastery of the use of electronic systems and software in the contemporary automobile.
