EP2 Vehicle Diagnosis Verify correct camshaft timing. Retrieve and record stored OBD I and OBD II diagnostic trouble codes; clear codes. Inspect & test computerized engine control system sensors, powertrain control module (PCM), actuators, and circuits. Competence-based reporting Each on-screen assignment is designed around a list of performance objectives. These include academic, technical, and occupational objectives. The assignments are written in such a way as to enable a student to attain the performance objectives, with the assessment questions linked to these in order to provide a measure of true competency. The performance objectives are used by the ClassAct management system to generate a comprehensive portfolio of student competency reports. The module includes a default competence report addressing the latest NATEF standards. EP2 is a computer-based instructional module that has been designed to teach the fundamentals of vehicle diagnosis. The curriculum materials provided in the module are divided into a series of onscreen, interactive assignments. All assignments incorporate continuous assessment through questions. When used in conjunction with a ClassAct networked management system, this provides instant feedback of student performance. On-screen theory assignments provide essential knowledge of diagnosing vehicle problems. They are supported by standard automotive textbooks. The classroom work includes the use of vehicle fault diagnosis simulation software that runs on the student’s PC. This provides a generic simulation of a vehicle with an OBDII compatible engine management system. The simulation also provides: Fault insertion and removal. Breakout box monitor points and waveforms. In circuit/out of circuit tests on sensors and actuators. Virtual hand-held diagnostics scanner. On-screen-simulated workshop reference manual. In addition, the module also provides a series of auto shop practical tasks. The student will identify sensors and actuators including MAF, TPS, ECT, O2, crank, coil, and fuel injectors. The student will investigate the operation of these components using oscilloscopes, scan tools, and engine analyzers. www.ljcreate.com These activities are designed to teach the student how to carry out diagnostic procedures using manufacturer’s service data in relation to fault codes generated by the scan tool. Instructor Materials A range of instructor materials is provided, including: An Instructor Guide, containing full installation instructions, health & safety guidance, typically completed work, and correct answers to all questions. A checklist that identifies how the assignments address NATEF requirements. Student assessment sheets (allowing student tasks to be assessed against specific NATEF statements), plus assessor marking sheets. Student response sheets (allowing students to record their question responses if the ClassAct management system is not available) Health and safety sheets. Curriculum material topics include: Basic engine diagnosis. Engine leak inspection. Manifold pressure and cylinder compression tests. Cylinder power balance and leakage tests. Valve adjustment and camshaft timing. Retrieval of OBDI and OBDII fault codes. Inspection and testing of actuators and transducers. Fault diagnosis of actuator and transducer circuits. Typical practical tasks include: Ref No. P4980-D Identify basic engine diagnosis including unusual engine noise or vibration concerns, and unusual exhaust color, odor, and sound. Access and use electronic service information (ESI). Inspect engine assembly for fuel, oil, coolant, and other leaks. Inspect and test thermostat, by-pass, and housing. Perform engine absolute (vacuum/boost) manifold pressure tests and cylinder compression test. Perform cylinder power balance test and cylinder leakage test; determine necessary action. Adjust valves on engines with mechanical or hydraulic lifters.
