Hood Ajar Switch

Disconnect and isolate the negative battery cable. If equipped with an Intelligent Battery Sensor (IBS), disconnect the IBS connector first before disconnecting the negative battery cable.

Check for resistance between the two terminals of the hood ajar switch. There should be continuity with the hood ajar switch open (compressed), and 500 ohms with the hood ajar switch closed (extended). If not OK, replace the ineffective hood ajar switch. If OK, go to Step 4.
Test the ground circuit between ground and the hood ajar switch for continuity. If not OK, repair the open ground circuit as required. If OK, go to Step 5.
Test the signal circuit between the hood ajar switch and the Body Control Module (BCM) for continuity to ground. There should be no continuity. If not OK, repair the shorted signal circuit as required. If OK, go to Step 6.
Test the circuit between the hood ajar switch and the BCM for continuity. There should be continuity. If not OK, repair the open circuit as required. If OK, go to Step 7.
Reconnect the negative battery cable, then reconnect the IBS.
Use a diagnostic scan tool and the appropriate diagnostic procedure to complete testing of the BCM.
