Latch Mounted Hood Ajar Switch

WARNING: This page is about a different car, the 2013 RAM 3500 HD and 2013 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.
  1. Disconnect and isolate the negative cable from the battery.
  2. Disconnect the wire harness connector from the hood ajar switch.
  3. Check for continuity between the two terminals of the hood ajar switch. There should be continuity with the hood latch open, and only the continuity of the 1 kilohm diagnostic resistor with the hood latch closed. If OK, use a diagnostic scan tool and the appropriate diagnostic procedure to complete testing of the Body Control Module (BCM) (also known as the Common Body Controller/CBC) as well as the circuits between the BCM and the hood ajar switch. If not OK, replace the ineffective hood ajar switch.
