Hood Ajar Switch
WARNING: This page is about a different car, the 2008 Cadillac STS. 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 RIM for RVS purposes. The switch is integrated into the hood latch assembly. The hood ajar switch provides 2 separate inputs to the RIM. These separate inputs allow the RIM to actively monitor for a hood ajar switch fault.
