INTRODUCTION Course Objectives Upon completion of the Engine Performance Diagnosis and Testing classroom course, you will be able to: • Use the SSCC diagnostic process to diagnose engine performance concerns • Explain how to perform diagnostic tests − − Quick Tests V KOEO on-demand self-tests, KOER on-demand self tests, Continuous memory self-tests PID Monitor • Explain PCM circuits and wiring • Use critical thinking skills and available resources to diagnose and test specific engine performance systems, including: − − Ignition system V V V V Identify the types of misfires Explain the relationship of ignition patterns to diagnosis Explain how to diagnose misfire concerns Explain how to diagnose no start concerns Fuel System V Fuel delivery ⇒ Identify the types of fuel delivery systems ⇒ Describe conditions related to fuel delivery concerns V ⇒ Describe the testing related to fuel delivery concerns Fuel control ⇒ Describe how to diagnose a contaminated MAF sensor ⇒ Identify open/closed loop conditions ⇒ Explain conditions related to abnormal fuel trims ⇒ Describe the testing related to fuel control concerns − Air Inlet System V V − Explain the conditions and tests related to diagnosing and testing the IAC valve Explain the conditions and tests related to diagnosing and testing Controlled Air Inlet Systems Exhaust/Emissions System V Explain the conditions and tests related to diagnosing specific emission systems, including PCV, EGR, CAT, and EVAP • Explain the basic operation of the Passive Anti-Theft System (PATS) • Using available resources, perform hands-on diagnosis and testing of specific engine performance systems including, Ignition, Fuel, Air Inlet, and Emissions Intro April, 2002 Diagnosis and Testing INTRODUCTION Classroom Multimedia Training (CMT) The CMTs are workstation activities delivered via CD and include video and audio elements These are simulated hands-on practice in diagnosis and testing of driveability concerns The PCED information is included in each activity The CMTs include: • Scenarios – These are DTC driven routines that address driveability concerns • Interactive Exercises – These exercises allow you the opportunity to apply the information presented during instruction PC-Assisted Activities The PC-assisted activities are workstation activities delivered via CD They not include the use of video and audio elements These are simulated hands-on practice in diagnosis and testing of driveability concerns with heavy emphasis in using the actual PCED (hard copy or electronic) The PC-assisted activities include: • Scenarios – These are DTC driven routines that address driveability concerns • Interactive Exercises – These exercises allow the technicians the opportunity to apply the information presented Evaluation Strategy Your evaluation is based on the score of a final written test and a hands-on workstation These are completed on the afternoon of the last day A non-passing grade in either of these two evaluation areas constitutes a failing grade for the course There are no make-up tests or "do-overs" available Any technician that fails this course must sign up to take the course for a second time Final Written Test You complete the final written test at your seat The written test consists of 30 multiple-choice questions The questions focus on diagnostic concerns and processes identified during the classroom session and require critical thinking skills to solve problems You must correctly answer 80% of these questions (24 of 30 questions) to pass Final Hands-on Workstation You must diagnose the final hands-on workstation and correctly answer all of the accompanying worksheet questions with 100% accuracy The hands-on activity is done without instructor assistance and the worksheet must be completed individually You may use all of the reference material available to you in the classroom, including workshop manuals and the student reference book Diagnosis and Testing April, 2002 Intro ... no make-up tests or "do-overs" available Any technician that fails this course must sign up to take the course for a second time Final Written Test You complete the final written test at your... diagnosis and testing of driveability concerns with heavy emphasis in using the actual PCED (hard copy or electronic) The PC-assisted activities include: • Scenarios – These are DTC driven routines... hands-on practice in diagnosis and testing of driveability concerns The PCED information is included in each activity The CMTs include: • Scenarios – These are DTC driven routines that address driveability
