Hood Sensor/Switch (For Alarm): Description and Operation

The hood switch is located in the engine bay at the front and is included as a sensor for the bonnet. The switch is connected to the control module (pin 16).
- When the hood is closed, the voltage between the switch and ground should be +12 V.
- When the hood is opened, the switch is grounded. The voltage between the switch and ground is thus 0 V. The alarm is set off.
