Dive into the complexities of EVAPorative emissions systems across domestic, Asian-Pacific, and European platforms. This course covers both pressure-based and vacuum-style EVAP designs, highlighting diagnostic techniques that go beyond the basics. Learn how to identify leaks using pressure testing, smoke machines, and CO₂ detection – and compare those results with onboard bi-directional tests. We’ll explore scan data interpretation, global OBD Mode values, and the tools that make diagnostics more accurate and efficient. You’llalso see how EVAP behavior and testing strategies shift between naturally aspirated and turbocharged applications, giving you a complete picture of system performance and repair.

Recommended for seasoned and aspiring diagnostic technicians.

Every day, as technicians, we are confronted with electrical faults. It is almost impossible to name a system in a vehicle that is not electronically controlled or monitored. This means we should be a Master of Electrical testing. This course builds | a foundation of electrical theory and testing to use on every vehicle.

You will learn functions that your DVOM has but are seldom used to become more proficient in your testing and achieve the results you need. We cover the benefits of voltage drop versus standard voltage potential testing. We willalso explore the value of current charging versus ohmic or resistance testing. These two tests alone will fundamentally change the way you approach electrical faults and, more importantly reduce the amount of time you spend diagnosing them.

Recommended for all levels of technicians.

• Voltage Drop
• AC and DC Voltage Tests
• Current Charging • Resistance Testing
• Diode and Component Tests
• Frequency Testing
• Temperature Testin
