Diesel Aftertreatment Emission Systems
Fault codes related to diesel aftertreatment system often result in inconvenient vehicle downtime and expensive repair costs.
Technicians who are trained specifically in diesel aftertreatment system theory and operation can prevent system failures, reduce fault codes, minimize vehicle downtime, and most importantly significantly reduce expensive maintenance and repair costs.
This course, based on EPA diesel emission regulations, spans all major engine manufacturers, and teaches technicians troubleshooting and service procedures surrounding current diesel engine aftertreatment emission control systems.

Kevin Vieth founded VieTech Training & Consulting Inc. in 2016 out of a passion for empowering heavy-duty and automotive service technicians through technical training. Due to the fast pace of technological advancements, he believes that on-going knowledge and skill development is imperative. With the operational pressures applied to business managers, skills training can be inconvenient, inaccessible and costly. This motivated Kevin to develop the Diesel Engine Technology Fundamentals in-class training curriculum to provide relevant and realistic diesel technology diagnostic training that is on-site, on-time and on-budget.
As a former technical Training Instructor for Cummins Western Canada, Kevin has delivered over 125 Cummins engine certification courses to over 500 heavy-duty technicians. Prior to his time with Cummins, he worked as a journeyman 310S automotive technician and then spent 3 years as a technical lead for Westport Innovations, a world leader in natural gas fuel system development. Kevin’s experience as a service technician, combined with his knowledge of fuel, emissions and engine controls acquired at Westport, helped him excel as a Cummins trainer and in diesel engine fault troubleshooting.
In addition to delivering on-site diesel engine diagnostic training to fleets nation-wide, Kevin also provides on-going remote troubleshooting and technical support to his clients.
