Technical Service Bulletin ITB13052 — 2012 INFINITI M45

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.
