What you can expect to learn:

Low fuel rail pressure fault codes and low-power conditions remain some of the most commonly undiagnosed and misdiagnosed complaints on today’s diesel powertrains. This results in comebacks and unnecessary vehicle downtime. Our High Pressure Common Rail Fuel System training breaks down modern electronically controlled fuel systems utilizing Bosch and Cummins systems found on ISB, ISC, ISL and ISX (12L & 15L) engines as an example. Technicians who successfully complete this training course will possess the knowledge and understanding of modern High-pressure common rail fuel system components, work practices and diagnostic procedures. Regardless of manufacturer, the fundamental theory and operation remains the same. Lessons learned in this training course are transferrable across multiple makes, models, and industries.

  • In Basic Level training, technicians will learn the fundamentals of electronic fuel control theory for high pressure common rail systems along with system components, flow, and work practices. Breaking down the system to its core components lays the foundation for troubleshooting and service of high pressure common rail fuel systems. Basic level training alone will provide a new perspective and appreciation for exactly how simple and effective these systems are.

  • Advanced training is where technicians will gain an in depth look at common failures that can occur and the testing procedures required to identify them. Additionally, the troubleshooting process will be stripped-down into three fundamental causes of a given high-pressure common rail fuel system fault.

  • Expert Level Training provides technicians with a Quick-Reference Diagnostic Flow Chart for High-Pressure Common Rail (HPCR) Fuel System troubleshooting. This is a one-page reference that can be utilized for on-the-job fault troubleshooting for fuel rail faults. Troubleshooting “no fault code” low-power complaints is covered. Technicians will gain an understanding of different fueling strategies integrated into ECM calibrations and how they can cause poor acceleration and low-power conditions as well as how to identify one through engine data analysis.
