This course prepares you to diagnose and repair drivability problems on the engine control systems. Attend this course to learn about how the Cummins ISX handles OBD-II requirements for fuel control and emissions. The fuel system is an electronically controlled common rail fuel injection, computer controlled system. Information like the injectors using two drivers and not just one as the gasoline engine does is critical when diagnosing emission or drivability concerns.

This course covers the electronic fuel controlled common rail engines used on trucks. Service information, schematics, and scan data will be used to help the technician diagnose these vehicles in the service bay the next day.

• EGR Airflow Throttle Control Valve
• Exhaust Gas Recirculation Valve (EGR), EGR Cooler/Cooler By-Pass
• Turbochargers and Wastegate Operation
