Hood Switch
WARNING: This page is about a different car, the 2019 Nissan Armada and 2018 Nissan Armada. However, it is still accessible from the selected car via links, so may be relevant.
Hood switch detects that hood is open, and then transmits the signal to IPDM E/R. IPDM E/R transmits hood switch signal to BCM via CAN communication. For models with remote engine starter function, two hood switches are installed.
