To cancel parked regeneration, the driver can toggle the regeneration switch to ON for five seconds.

• A. False
• B. True
• C. Only when engine is off
• D. Only with supervisor

Answer: (B)

Understand that parked regeneration is a DPF cleaning mode that runs with the engine at a higher heat while the vehicle is stationary. To cancel that mode, the driver can toggle the regeneration switch to ON for about five seconds. This input signals the engine control module to exit the parked regeneration cycle and resume normal operation without turning off the engine or needing supervisor approval. The five-second duration is the specific window recognized by the system for canceling parked regen, so this is the quickest, approved way to regain regular driving without waiting for the cycle to finish. It’s not limited to when the engine is off, and it doesn’t require a supervisor.
