Counter System
WARNING: This page is about a different car, the 2011 Nissan Leaf. However, it is still accessible from the selected car via links, so may be relevant.
In this system, Operating power switch OFF==>ON is defined as 1 trip. When a malfunction is detected, the VCM saves the DTC and freeze frame data and continues saving it up to a maximum of 40 trips. In addition, if a DTC that is the same as the saved DTC is redetected, the counter is reset and the count-up starts from "0" again.
