Can Communication Control

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

When CAN communication with ECM and BCM is impossible, IPDM E/R performs fail-safe control. After CAN communication recovers normally, it also returns to normal control.
