This eLearning course looks at basic ignition system tests that can be performed by most general technicians. The practice of using basic spark testers, a digital volt-ohm meter (DVOM), performing thorough visual inspections and using an inductance ignition tester will be discussed. Read More

This eLearning online course covers the fundamentals of ignition coils. There will be an overview of coil design and operation. Methods on how to test different ignition types will be emphasized. Primary and secondary ignition patterns will be broken down into an understandable format. Ignition module control is also highlighted. Read More

This eLearning course identifies the different ignition inputs used by the PCM to trigger the ignition system. The different types of crankshaft position sensors (CKP) and camshaft position sensors (CMP) used by vehicle manufacturers are reviewed. Various locations of these components as well as Diagnostic Trouble Codes (DTCs) that can set when they fail are identified. We demonstrate what an intermittent CKP fault acts like through exploring a live vehicle demonstration captured on video. Several examples shown of bad components captured using both a scan tool and a digital storage oscilloscope (DSO) are shown. Read More

This eLearning course reviews how the PCM uses the CKP and CMP inputs to run misfire detection. The misfire monitor is one of the continuously ran Onboard Diagnostics (OBD) monitors whose logic is stored within the PCM. Engine misfires can lead to excessive hydrocarbon emissions and are mandated by the Federal Government to be detected by the vehicle’s engine management system. The reliability of this system is critical. The PCM uses the CKP and CMP sensors as its primary inputs to detect engine misfire. Read More

This eLearning course explains how to interpret different types of spark plug signs that are indicators of potential problems. Common misunderstandings amongst technicians as to what the definition of heat range is for a spark plug is dispelled. Installation tips are given, as well as common things to watch for when setting the gap on a spark plug. Read More

This eLearning course is a detailed breakdown of the components and technology behind monotube shocks and struts. The functions, benefits and features of monotube shocks and struts are discussed along with detailed diagrams and video of them in action. Read More
