The indicator signaling that automatic regen will no longer be allowed, and the vehicle should be moved to a safe location to perform a parked regen immediately, is which stage?

• A. First Stage
• B. Second Stage
• C. Third Stage(DPF flashing, and Check engine light illuminated)
• D. Fourth Stage

Answer: (C)

When the diesel particulate filter needs a burn-off but cannot complete it automatically, the system escalates to a parked regeneration cue. This is signaled by the DPF indicator flashing and the check engine light coming on. It tells you that automatic regeneration will no longer occur during driving, and you must move to a safe location to perform a parked regen immediately. Parked regen is done at idle with the vehicle safely stopped so exhaust temperatures can rise enough to burn off the accumulated soot in the filter. This stage is distinct from normal driving regen and from more severe fault states, and it requires driver action to protect the exhaust system and prevent damage.
