PINPOINT TEST A : The Alarm System Does Not Activate from an Unauthorized Entry at the Hood: Notes

Diagnostic Overview 

The Alarm System Does Not Activate from an Unauthorized Entry at the Hood 

Normal Operations and Fault Conditions 

When the alarm system is armed, the BCM monitors the hood switch. If the hood is opened while the alarm is armed, the hood switch removes ground from the signal circuit. This signals the BCM that an unauthorized intrusion to the engine compartment has occurred and the BCM activates the alarm.

Visual Inspection and Diagnostic Pre-checks 

Inspect the hood switch.
