Active Regeneration can occur in which modes?

Active Regeneration can occur in which modes?

• A. Automatic only
• B. Parked only
• C. Automatic and Parked
• D. Manual

Answer: (C)

Active regeneration is the controlled process that burns off soot in a diesel particulate filter by raising exhaust temperature. It’s typically triggered automatically by the engine control unit during normal driving when the filter soot load is high, so it can happen without driver input. It can also be initiated while the vehicle is parked (parked regeneration) to complete the burn without moving. Manual regeneration isn’t a standard everyday mode in most systems. Because it can occur in both automatic operation and while parked, the best answer is that active regeneration can occur in Automatic and Parked modes.
