DPF® After-Sales Regeneration
Precautions: General safety (00)
CAUTION:
Exhaust gas temperature from the muffler tail pipe becomes higher excessively (approx. 600 °C / 1112 °F) when after-sales regeneration is in operation. Failure to take proper precautions may result in a fire and personal injury.
Take the following precautions to reduce the risk of a fire and injury.
•Locate the vehicle in a well- ventilated outdoor area.
•Do not allow a person to come near the muffler tail pipe.
•Do not leave obstruction or inflammable material in the vicinity of exhaust system components.
•Do not allow a person to come near the muffler tail pipe.
•Do not leave obstruction or inflammable material in the vicinity of exhaust system components.
NOTICE:
•Stopping after-sales regeneration before it is completed may damage the DPF® due to thermal shock.
When after-sales regeneration is in operation, do not cancel the process through to the end without interruption.
•Turning the ignition “OFF” right after the after-sales regeneration may damage the DPF® due to thermal shock.
Keep the engine idling for 5 minutes to allow the DPF® to cool down.

1)Check engine oil level. 
If oil level is not as specified, adjust oil level referring to Engine Oil and Filter Change:D16AA.
If oil level is not as specified, adjust oil level referring to Engine Oil and Filter Change:D16AA.
2)Check that fuel level is 1/4 full or more.
3)Turn off all electrical loads.
4)Locate vehicle in a well-ventilated outdoor area.
5)Open hood.
6)Remove engine cover.
7)When ignition is “OFF”, connect SUZUKI scan tool to DLC.
8)Check DTC.
If DTC other than P1206 is detected, repair the malfunction according to applicable DTC troubleshooting.
If DTC other than P1206 is detected, repair the malfunction according to applicable DTC troubleshooting.
9)Start engine and wait until ECT reaches 70 °C (158 °F) or more.
10)Select “Regeneration” in “Utility” menu, and follow instructions displayed on SUZUKI scan tool.
11)After-sales regeneration is automatically performed as follows:
a)Phase 1: Check of DPF® differential pressure
Engine speed is raised to approx. 2,000 rpm.
Engine speed is raised to approx. 2,000 rpm.
NOTE:
If DPF® differential pressure is out of allowable range, “Error Retrieving” is displayed on SUZUKI scan tool.
Repair this faulty condition referring to “After-Sales Regeneration Failure”.
b)Phase 2: After-sales regeneration
Engine speed is raised to approx. 3,000 rpm and regeneration is started.
Engine speed is raised to approx. 3,000 rpm and regeneration is started.
NOTE:
Phase 2 will last for 5 to 15 minutes.
This period depends on soot deposit in DPF®.
c)Phase 3: End of regeneration
Engine speed decreases to idle speed.
Result of after-sales regeneration is displayed on SUZUKI scan tool in approx. 30 seconds.
Engine speed decreases to idle speed.
Result of after-sales regeneration is displayed on SUZUKI scan tool in approx. 30 seconds.
12)Check that display of SUZUKI scan tool shows “Regeneration is completed successfully.”.
If not, repair faulty condition according to After-Sales Regeneration Failure.
If not, repair faulty condition according to After-Sales Regeneration Failure.
13)Wait for 5 minutes at idle speed for engine cooling down.
14)Set ignition “OFF”, and wait for 30 seconds or more.
15)Set ignition “ON”.
16)Check DTC.
If DTC other than P1206 or P1564 is detected, repair the malfunction according to applicable DTC troubleshooting.
If DTC other than P1206 or P1564 is detected, repair the malfunction according to applicable DTC troubleshooting.
17)Clear DTC.
