ITB14056	2021-05-10. Service bulletin. SERVICE INFORMATION Starting with 2010 Model Year, Infiniti vehicles have been gradually incorporating a new type of DTC known as Permanent DTC or P-DTC. 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. See this bulletin for further detail.
