Which instrument panel light is the Diesel Particulate Filter (DPF) indicator?

• A. Diesel Particulate Filter (DPF)
• B. High Exhaust Temp (HEST)
• C. Malfunction Indicator Lamp (MIL)
• D. Stop Engine Lamp

Answer: (A)

The light that directly identifies the Diesel Particulate Filter is the one labeled Diesel Particulate Filter. This indicator specifically signals the status of the DPF, such as soot buildup and the need for regeneration or service. Other lights serve different purposes: High Exhaust Temp warns about excessive exhaust temperatures (often related to regen but not the DPF label itself), the Malfunction Indicator Lamp is a general check-engine light, and the Stop Engine Lamp signals a critical fault requiring engine shutdown. So the DPF label light is the correct indicator for the Diesel Particulate Filter.
