Test C: The Alarm System Does Not Operate Correctly - Alarm Does Not Activate With Hood Ajar/Open

PINPOINT TEST C: THE ALARM SYSTEM DOES NOT OPERATE CORRECTLY - ALARM DOES NOT ACTIVATE WITH HOOD AJAR/OPEN

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

- DTC B1520 (Hood Switch Circuit Open) - sets when there is an open in the circuit between the hood switch and the SJB, an open in the ground circuit to the hood switch, or the hood switch is stuck open during the on-demand self-test. If the hood is detected as always being open, the perimeter alarm will never arm for the hood.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Hood switch
- SJB
