Low fuel rail pressure fault codes and low-power complaints are some of the most common - and most frequently misdiagnosed - issues in today’s diesel-powered vehicles. This course is designed to help technicians confidently navigate these challenges by breaking down the design, operation, and diagnostic approach for modern electronically controlled High-Pressure Common Rail (HPCR) fuel systems, using Cummins and Bosch systems as practical examples.
Throughout the training, you’ll develop a strong understanding of HPCR system components, safe work practices, and the critical importance of fuel system cleanliness. You’ll also explore the impact of fuel contamination on system performance and learn best practices for preventing costly damage and repeat failures.
This course also provides a clear, step-by-step approach to troubleshooting HPCR systems, including accurate diagnosis of low-power complaints and interpreting fuel rail pressure fault codes. The knowledge and techniques gained here are transferable across a wide range of makes, models, and industries - ensuring you can apply what you learn in real-world scenarios with confidence.
