Hood Ajar Switch
WARNING: This page is about a different car, the 2007 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.
The hood switch provides status of the hood to the body control module for remote vehicle start (RVS) and content theft deterrent (CTD) functions. It is integrated into the hood latch assembly. The hood ajar switch provides 2 separate inputs to the body control module (BCM). These separate inputs allow the BCM to actively monitor for a hood ajar switch fault.
