## NHTSA's summary

The modified parked regeneration strategy has been standard on GHG17 units since the start of GHG17 production and was added to EPA10 and GHG14 units with a software update. The modified regeneration utilizes an improved strategy to clean the DOC inlet face and reduce downtime due to DOC face plugging.
