Dive deep into the evolution of Cummins B/C/L & X model Aftertreatment Emission Systems with Kevin Vieth from VieTech. In this 4-hour virtual classroom session, Vieth will teach you all about the operation, control strategies, and diagnostic procedures from 2004 through 2017. This class is ideal for both diesel technicians and heavy-equipment technicians and other technical support staff. Please note, the registered student will receive their virtual workbook via email one week prior to class. Please provide a valid email address for the delivery of the virtual workbook upon order placement.

Course Overview
This virtual classroom training will focus on EPA Heavy-Duty Diesel Engine emissions regulations and the technology Cummins uses to meet these requirements. The content of this class will directly relate to the developments, product changes, troubleshooting, and service procedures surrounding current Cummins diesel aftertreatment emission control systems.
