Diesel Particulate Filter
Diesel Particulate Filter (SKYACTIV-D 2.2)
The diesel particulate filter collects and removes most of the particulate matter (PM) in the exhaust gas of a diesel engine.
PM collected by the diesel particulate filter is cleared during normal driving, however, PM may not be removed and the diesel particulate filter indicator light may illuminate under the following conditions:
-
If the vehicle is driven at 15 km/h (9 mph) or less continuously.
-
If the vehicle is repeatedly driven for a short period of time (10 minute or less) or driven while the engine is cold.
-
If the vehicle is idled for a long time.
With Instrument cluster (Type A/B)
When “Soot Accumulation in DPF too high” is indicated
The particulate matter (PM) cannot be removed automatically and the amount of collected PM reaches a specified amount.
After the engine has sufficiently warmed up (engine coolant temperature of 80 °C (176 °F) or more), depress the accelerator pedal and drive the vehicle at a speed of 20 km/h (12 mph) or more for about 15 to 20 minutes to eliminate the PM.
When “DPF malfunction” is indicated
Contact an expert repairer, we recommend an Authorised Mazda Repairer.
If the vehicle continues to be driven with “Soot Accumulation in DPF too high” indicated in the display, the particulate matter (PM) increases and the indication may change to “DPF malfunction”. If the indication changes to “DPF malfunction”, have the vehicle inspected immediately at an expert repairer, we recommend an Authorised Mazda Repairer. If the vehicle is not inspected and continues to be driven, the engine may malfunction.
-
When “DPF malfunction” is indicated in the display, the engine output is restricted to protect the diesel particulate filter.
-
The engine sound and exhaust gas smell may change when PM is being removed while driving.
With Instrument cluster (Type C)
When illuminated
The particulate matter (PM) cannot be removed automatically and the amount of collected PM reaches a specified amount.
After the engine has sufficiently warmed up (engine coolant temperature of 80 °C (176 °F) or more), depress the accelerator pedal and drive the vehicle at a speed of 20 km/h (12 mph) or more for about 15 to 20 minutes to eliminate the PM.
When flashing
Contact an expert repairer, we recommend an Authorised Mazda Repairer.
Refer to Indication/Indicator Lights (Search).
If the vehicle is continually driven as usual with the diesel particulate filter indicator light illuminated, PM increases and the indicator light may start flashing. If the diesel particulate filter indicator light starts flashing, have the vehicle inspected immediately at an expert repairer, we recommend an Authorised Mazda Repairer. If the vehicle is not inspected and continues to be driven, the engine may malfunction.
-
When the diesel particulate filter indicator light flashes, the engine output is restricted to protect the diesel particulate filter.
-
The engine sound and exhaust gas smell may change when PM is being removed while driving.
