What is a Regen

In a commercial truck with the exhaust filter can become clogged over time. This extra soot that has built up will need to be burned (cleaned) out. In most cases if the vehicle is used for a lot of highway driving, this process will happen automatically while driving.

The buildup occurs when a truck idles a lot or is used for a lot of city driving. In this case, a warning light on the dash will light up informing the driver that it is time to perform a parked (manual) regen. Basically, you park your truck, push the manual regen button and the engine will rev up and heat up burning out the excess soot.
