Hood Switch

WARNING: This page is about a different car, the 2021 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.

Hood switch is located under front of hood.
Hood switch is integrated into hood lock assembly. Hood switch detects that hood is open and then transmits ON/OFF signal to IPDM E/R. IPDM E/R transmits hood switch signal to BCM via CAN communication.
