DPF WARNING LIGHT IS ON
APPLIED VEHICLE:

2016 Titan XD (A61)

APPLIED ENGINE:

Cummins 5.0L

IF YOU CONFIRM:
The Diesel Particulate Filter (DPF) warning light is ON
AND/OR
The Vehicle Information Display states “Exhaust Filter Overloaded See Owner’s Manual
For Drive Pattern”
AND
DTC P1451 (Diesel Particulate Filter System Performance) is stored in the ECM
NOTE: This DTC will not turn the MIL ON.
AND
The vehicle has less than 100 miles on the odometer.

ACTION:
1. Perform a stationary regeneration.


Go to SERVICE PROCEDURE on page 2.

2. Erase the DTC.

IMPORTANT: The purpose of ACTION (above) is to give you a quick idea of the work you
will be performing. You MUST closely follow the entire SERVICE PROCEDURE as it
contains information that is essential to successfully completing this repair.
Nissan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are
properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job
properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO
NOT assume that it does. See your Nissan dealer to determine if this applies to your vehicle.

SERVICE PROCEDURE

Stationary Regeneration
NOTE: If the vehicle mileage is not less than 100 miles, this bulletin does not apply.
Refer to ASIST and the Electronic Service Manual (ESM) for further diagnosis of DTC
P1451.
WARNING: Exhaust system components can become hot enough during operation and
testing to cause burns or ignite and melt combustible materials. The exhaust and
exhaust components can remain hot after the vehicle stops moving and has been shut
down. To avoid the risk of fire, property damage, burns, or other serious personal injury,
allow the exhaust system to cool before beginning repairs or service. Make sure that no
combustible materials are located where they are likely to come in contact with hot
exhaust or exhaust components.

1. Select an appropriate location to service the vehicle.


An “appropriate location” would be where the ground surface will not burn or melt
under high temperatures (such as clean concrete or gravel, not grass or asphalt)
and away from anything that can burn, melt, or explode.

2. Make sure anything that can burn, melt, or explode is more than 1.5 m (5 ft) away from
the vehicle.


Examples include, but are not limited to, gasoline, wood, paper, plastics, etc.

3. Park the vehicle securely.


Put the transmission in Park.



Apply the parking brake.



Set wheel chocks at the front and rear of at least one tire.

4. Set up a safe exhaust area.


Use barriers to keep people at least 1.5 m (5 ft) away from the exhaust tailpipe
during stationary regeneration.



If indoors, attach an exhaust discharge pipe rated for at least 800°C (1,500°F).



Have a fire extinguisher close by.

5. Inspect the exhaust system.


Make sure there is nothing on or near exhaust system surfaces (for example, tools,
shop cloths, grease, debris, etc.).

6. With engine speed changes during stationary regeneration, stay clear of the engine
compartment.

7. Connect the CONSULT PC to the vehicle.
8. Open / start C-III plus.
9. Start the engine, let the engine idle.
10. Wait for the plus VI to be recognized.


The Serial No. will display when the plus VI is recognized.

11. Select Diagnosis (All Systems).

Step 10:
plus VI is
recognized

13. Verify there are no DTCs other than DTC P1451.
a. If any DTCs are found stored other than P1451, STOP HERE. Diagnose and repair
as needed before continuing the service procedure.
 Diagnosis and repairs related to any stored DTCs other than P1451 are not part
of this bulletin.
b. With no other DTCs stored, select ENGINE.

IMPORTANT: Access all related Notes, Cautions, and Warnings by selecting the
arrow buttons where shown in Figure 6.
18. Make sure DPF SOOT LOAD appears.


DPF SOOT LOAD may be on the second page.
 Select the arrow button to get to the second page.

19. Select Start.
NOTE:


Once the Aftertreatment DPF Regeneration Test is started, follow CONSULT
electronic service tool on screen instructions. When the test is started, the engine
idle speed will be raised automatically to the required level.



The engine will, through engine controls, operate in a manner to build exhaust heat.
The turbocharger will emit a slight whining noise during this test. This is normal.



Once the Aftertreatment DPF Regeneration Test is complete, the engine will
automatically return to normal idle speed.



Make sure the vehicle and surrounding area is monitored during regeneration.
If any unsafe condition occurs, shut the engine OFF immediately.

20. Monitor DPF SOOT LOAD, make sure it drops to 9 grams or below (see Figure 7).


Do not select End or Stop until C-III plus states the stationary regeneration process
has “stopped” on its own.



If the stationary regeneration needs to be stopped for any reason at any time
while in progress, stop it by performing one of the following:
 Select End or Stop on the C-III plus screen.
 Depress the brake pedal.
 Depress the accelerator pedal, or
 Turn the engine OFF.

21. When the stationary regeneration completes, the screen in Figure 8 will appear. Select
End.


At this time, exhaust gas and exhaust surface temperatures will remain elevated for
three to five minutes.



During the 3-5 minute period, letting the engine idle will allow the exhaust gas and
surface temperatures to cool.
NOTE:
 Do not select End until C-III plus states the stationary regeneration process has
completed on its own (see “completed” screen in Figure 8).
 If End is selected before self-completion, C-III plus will still show the process
as complete regardless of the gram count.
 If this occurs, the vehicle will not be properly repaired and the stationary
regeneration process will need to be performed again.

22. Once the stationary regeneration is complete, check for DTCs and/or engine indicator
lamps for high diesel particulate soot load.
 Erase DTC P1451 now.
 If any active DTCs are present, follow the appropriate DTC diagnostic information in
the ESM.
23. Close C-III plus.
24. Turn the ignition OFF.
25. Disconnect the plus VI from the vehicle.
