Service bulletins for the 2013 Infiniti QX56

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

ITB150242021-05-10. 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.
ITB140562021-05-10. 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.

SERVICE INFORMATION Intelligent Key (I-Key) systems on the Applied Vehicles use two (2) different Radio Frequencies (RF) that are similar to other wireless devices; 315 MHz and 433 MHz. In the event another wireless device (e.g. aftermarket alarm system) is transmitting at the same time as an I-Key, it can interfere with the I-Key signals being received by the BCM. If there is interference with I-Key signals, the following symptoms may occur: - The I-Key is not detected, causing: - The engine to not start (no response when the Stop/Start button is pressed) - "I-Key System Error" displayed in the instrument cluster - "No I-Key Detected" displayed in the instrument cluster - Intermittent operation of the buttons on the remote (Key FOB). - Intermittent operation of the door request switches. If a vehicle has experienced the above symptoms, or a customer has reported the above symptoms, refer to Supplemental Diagnosis / Information in this bulletin. See this bulletin for further detail.
