Perform the test in accordance with the message.
note
If the fulfillment condition is not satisfied, DPF regeneration test will fail.
This procedures is to forcibly regenerate the DPF with scan tool when the DPF doesn't have been regenerated during driving. For example, if the vehicle has repeated "Low speed driving" or "Short distance driving", the DPF regeneration procedure cannot be proceeded because "Regeneration Mode" doesn't made.
If performing the DPF service regeneration mode indoors, fire or burn injuries may occur by high-temperature exhaust gas.
Therefore the DPF service regeneration mode must be performed in a outdoor safe zone.
Engine coolant temperature: about 70℃
Engine at idle
P-range (A/T) or Neutral (M/T)
Normal battery voltage
Electrical fully load ON (A/C ON if equipped, Blower ON with maximum speed, Head Lamp ON, Wiper ON, Other Lamps ON, etc.)
The air conditioner's electrical load is very high. Accordingly, to make regeneration mode more quickly, turn it ON (If eqquipped).
Turn ignition switch OFF.
Connect a GDS to Data Link Connector (DLC).
Start engine at idle and P-range (A/T) or neutral (M/T).
Apply electrical fully load to the vehicle (A/C ON, Blower ON with maximum speed, Head Lamp ON, Wiper ON, and Other Lamps ON, etc.)
Select "Vehicle, Model year, Engine, System".
