Perform the test in accordance with the message.
note
If the predefined conditions are not satisfied, DPF regeneration test will fail.
This procedure regenerates the DPF by force using scan tool when the DPF regeneration procedure cannot be performed while driving. In the following cases, the DPF regeneration procedure may not be performed as the vehicle cannot enter "Regeneration Mode" while driving.
Low speed driving
Short distance driving
Driving with frequent stops
When performing the DPF service regeneration mode indoors, fire or burning injuries may occur due to high temperature exhaust gas.
Therefore, perform the DPF service regeneration mode only in an outdoor safe zone.
Engine coolant temperature: Approximately 70℃
Engine at idle
P-range (A/T) or Neutral (M/T)
Normal battery voltage
Full electrical load ON (A/C ON if equipped, Blower ON at maximum speed, Headlamps ON, Wipers ON, Other Lamps ON, etc.)
The electrical load of air conditioner is very high. Accordingly, to reach regeneration mode quickly, turn it ON (if equipped).
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 full electrical load to the vehicle (A/C ON, Blower ON at maximum speed, Headlamps ON, Wipers ON, and Other Lamps ON, etc.)
Select "Vehicle, Model year, Engine, System".
Select "Vehicle S/W Management".
Select "DPF Service Regeneration".
Perform the test in accordance with the message.
If the predefined conditions are not satisfied, DPF regeneration test will fail.
Always check for damaged DPF assembly before removing it.
Remove the exhaust pipe from the DPF end. Check for damage or decoloration (white) of the rear section of the DPF.
Check for soot from the rear section of the DPF. If black soot is found, DPS assembly is likely faulty.
Turn the ignition switch OFF and disconnect the battery negative (-) terminal.
Remove the under cover.
(Refer to Engine and transaxle assembly in this group)
Remove the alternater.
(Refer to Engine Electrical System - "Alternator")
Disconnect the wiring connectors and harness clamps and remove the wiring protector around the exhaust manifold.
Disconnect the wiring mounting bracket (A).
Remove the exhaust manifold heat protector (A).
