Diesel Aftertreatment Emission Systems Training

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 one-day 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.
