Counter System
WARNING: This page is about a different car, the 2013 Nissan Leaf. However, it is still accessible from the selected car via links, so may be relevant.
In this system, "Power switch is turned OFF→ON" is defined as 1 trip. VCM detects malfunctions while saving the DTC and freeze frame data and continues saving this data for a maximum of 40 trips. In addition, if a DTC that is the same as the saved DTC is detected again, the counter is reset and the count up starts from "0" again.
