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)

Diagnostics, or fault finding, is a fundamental part of an automotive technician's work, and as automotive systems become increasingly complex there is a greater need for good diagnostic skills. Advanced Automotive Fault Diagnosis is the only book to treat automotive diagnostics as a science rather than a check-list procedure. Each chapter includes basic principles and examples of a vehicle system followed by the appropriate diagnostic techniques, complete with useful diagrams, flow charts, case studies and self-assessment questions. The book will help new students develop diagnostic skills and help experienced technicians improve even further. This new edition is fully updated to the latest technological developments. Two new chapters have been added – On-board diagnostics and Oscilloscope diagnostics – and the coverage has been matched to the latest curricula of motor vehicle qualifications, including: IMI and C&G Technical Certificates and NVQs; Level 4 diagnostic units; BTEC National and Higher National qualifications from Edexcel; International Motor Vehicle qualifications such as C&G 3905; and ASE certification in the USA.

Make Your Own Diagnostic Equipment (MYODE)This book, “Make Your Own Diagnostic Equipment” came about from the need of many readers and viewers to be able to make and maintain fairly simple diagnostic gadgets. It is meant to show and guide the professional technician and DIY mechanic on how to make these gadgets. In many cases, due to the nature of the equipment industry, it is very expensive or virtually impossible to get these tools. The reason being is that often times tool makers don't see a profit in making these simple but effective gadgets. Most, if not all of these tools, are invaluable in diagnosing modern automotive systems. You can estimate that having one of these tools, at the right time when needed, will cut your diagnostic time by at least 50%. Of course, knowing how to use it is also important. However, by definition if you've already studied how the gadget works, how to build it an also ended up building it yourself, you've already passed the learning curve and chances are you'll know how to use it. At the very least, reading this book will put you in a much better position to also asses diagnostic issues and on the use of other important tools of automotive diagnostics. It is our hope with this work to enlighten the professional and DIY mechanic on the use, construction and operation of modern automotive diagnostic gadgets. Use this information to the beast of your abilities and be on the diagnostic driver seat.Table of Contents• Automotive Low Pressure Transducer • Building the Low Pressure Transducer • Using the Low Pressure Transducer • Polarity LED Test Light • Using the Polarity LED Test Light • Stress Loaded Test Light • Using the Stress Loaded Test Light • Building the Stress Loaded Test Light • Fuel-Pump Relay & the Stress Loaded Test Light • Dual Polarity & 5 Volt Reference Test Light • Amplified Sensor Tester • Injector & Coil Magnetic Detector • Fuel Injector Pulser • ECM-ECU Memory Saver Tool• Loaded Injector Noid Light • Using the Loaded Injector Noid Light • 5 Volt Reference Simulator • Parasitic Draw Amp Meter • Using the Parasitic Draw Amp Meter • Fuse Voltage Drop Short Identifier • How to Use the Fuse Voltage Drop Short Identifier • Ignition Primary DIS - COP Probe • How to Use the Ignition Primary DIS Probe • Drive-By-Wire Motor Actuator Controller • How to Use the Drive-By-Wire Actuator Controller • Ignition Key Transponder Detector • Using the Ignition Key Transponder Detector • Magnetic Sensor Induction Simulator • Using the Magnetic Sensor Induction Simulator • O2 Sensor Simulator • Using the O2 Sensor Simulator• ABS Speed Sensor Simulator • Using the ABS Speed Sensor Simulator • ABS Speed Sensor Simulator, Bleeding the Brakes • Optical CAM and CRANK Sensor Simulator • Using the Optical CAM and CRANK Sensor Simulator • OBD-2 Data Link Connector Breakout Box • Using the OBD-2 DLC Breakout Box
