Normal Operation
The hood ajar switch is a normally closed switch. The SJB receives the hood ajar switch status through circuit CPL25 (BU/OG), the hood ajar switch, and the hood ajar switch ground circuit GD123 (BK/GY). When the hood is open, the hood ajar switch opens, removing the ground to the SJB.

Possible Causes
- circuit CPL25 (BU/OG) open or short to ground
- circuit GD123 (BK/GY) open
- hood ajar switch
- SJB
