Wake-up operation

WARNING: This page is about a different car, the 2022 Nissan Frontier. However, it is still accessible from the selected car via links, so may be relevant.

BCM transmits the sleep wake up signal (wake up) to each unit when any of the CAN wake-up conditions are fulfilled. It changes from the low power consumption mode or the CAN communication sleep mode to the normal mode.
Each unit starts the transmission of CAN communication with the sleep wake up signal. In addition, the combination meter transmits the wake up signal to BCM via CAN communication to report the CAN communication start.
