- [ITB15024](/bulletins/10192589.md), 2021-05-10, Service bulletin: ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL. SERVICE INFORMATION After ECM reprogramming, the Calibration Verification Number \(CVN\) needs to be automatically calculated prior to State emissions testing \(also known as Inspection Maintainence, I/M, or SMOG testing depending upon location\). Allowing the vehicle to idle for 22 minutes will allow for faster CVN calculation. It is recommended that customers utilize this method if the vehicle needs to be tested for emissions soon after ECM reprogramming. See this bulletin for further detail.
- [ITB14056](/bulletins/10192479.md), 2021-05-10, Service bulletin: ENGINE; ELECTRICAL SYSTEM. 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.
