PERMANENT DTC (P-DTC) INFORMATION
APPLIED VEHICLES: 2010 and newer – see Applied Vehicles chart on page 4.

SERVICE INFORMATION
Starting with 2010 Model Year, Nissan vehicles have been gradually incorporating a new
type of DTC known as “Permanent DTC or P-DTC”. Please refer to the P-DTC Applied
Vehicles list on page 4.


If a vehicle is equipped with P-DTCs, all emission related DTCs will also set a
P-DTC if the MIL is turned ON.



A listing of which DTCs that will also set a P-DTC is found in the DTC Index in the
EC-Engine Control section of the Electronic Service Manual (ESM).

If a DTC repair is performed and the DTC erased, a vehicle may fail an Emission Inspection
and Maintenance test if the P-DTC is not also erased.

P-DTC’s can be erased by following the correct driving pattern:


Use CONSULT-III plus (C-III plus) to confirm a P-DTC and determine the correct
driving pattern to erase it (see page 2).



Refer to the ESM, section EC-Engine Control, for driving pattern information. Look
under How to Erase a Permanent DTC and Diagnosis Description.



Details for driving pattern B and D are included in this bulletin, starting on page 2.

NOTE: In most cases, if repairs are complete, P-DTCs will erase with the customer
driving their vehicle in their normal daily use.

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.

Driving Patterns B and D for Erasing P-DTCs

NOTE:


The DTC Index in the ESM, for vehicles equipped with P-DTCs, includes a Group
classification of “A” or “B” for DTCs that also set P-DTCs. P-DTC with a Group
classification of B requires completion of driving pattern B and D to erase the PDTC. In most cases, completion of driving pattern B will also complete driving
pattern D.



With C-III plus, use PERMANENT DTC WORK SUPPORT while performing driving
patterns.



Make sure to obey all traffic laws and speed limits when performing driving patterns.
