The indicator that damage to the after-treatment device is eminent and a parked regen should be performed immediately is which stage?

• A. Fourth Stage( DPF flashing,check engine,stop engine illuminated)
• B. Third Stage
• C. Second Stage
• D. First Stage

Answer: (A)

This stage shows the most severe warning for the after-treatment system. When the DPF is signaling imminent damage and a parked regen must be done immediately, you’re being told to stop driving and start a parked regeneration right away. The combination of the DPF indicator flashing along with a check engine alert and a stop engine message means continuing to drive could push the system past its safe operating limits. A parked regen, performed with the vehicle stationary, raises exhaust temperatures in a controlled way to burn off accumulated soot without the added stress of road operation, helping protect the DPF and engine from damage. Earlier stages warn that regeneration is needed or in progress but aren’t as urgent as this final stage, which demands immediate action to prevent damage.
