Overview

Gasoline Direct Injection System Diagnosis:VSG11

Want the inside knowledge on GDI systems?
Come to the experts who know!

This course advances the skills of technicians who have a good understanding of manifold fuel injection systems by undertaking in-depth practical training on typical Gasoline Direct Injection applications.

The course covers the system variants, the components used, the operating modes and system diagnostics. The theoretical knowledge gained will complement the practical exercises completed during training, where system diagnostics using serial port data and testing of the system components using an oscilloscope form an integral part of the course.

This course is not suitable for technicians new to gasoline injection.

Course Content
• Overview of the system layout and design concept
• Design and function of the individual working components
• Air, fuel supply and exhaust system component operation
• Fuelling modes of operation and other unique system functions
• System testing and diagnosis

Prerequisites
• This is an advanced course requiring a high level of technical knowledge and skill. We therefore recommend that delegates are already familiar with manifold type gasoline injection systems. The Bosch courses VSTD9, VSG2 and VSG5 provide the essential prerequisite knowledge for this course
• Please see the Bosch Diagnostic Technician Flowchart for more information on the recommended pathway

Attainment
On successful completion of VSG11, delegates will be able to:
• Identify and state the function of a typical Bosch GDI system including the operating modes, the sensors and actuators
• Utilise serial diagnostic data and the oscilloscope for the testing of system component input and output signals
• Diagnose typical system running faults and perform system tests that determine the required system or component repairs
