Diesel Particulate Filter (DPF) Lamp

Solid illumination indicates a regeneration is required. Change to a more challenging duty cycle, such as highway driving, to raise exhaust temperatures for at least 20 minutes, or perform a stationary regeneration. See the engine operation manual for details.

Blinking indicates that a stationary regeneration is required immediately. An engine derate and shutdown will occur. See the instructions in the engine manufacturer's operator's manual to perform a stationary regeneration.
