Door and luggage compartment switches
|
The switches (for interior lighting) are included in the theft alarm as sensors for
doors and tailgate. The switches are mounted in the body. in the middle of each door and the
tailgate. All door switches are connected to the alarm control module (pin 4) via the
car's ICE control module. The luggage compartment switch is connected directly via the
car cable assembly to pin 3 on the alarm control module. The control module then senses if a
door is opened when the alarm is armed by monitoring the voltage over the switch as follows:
|
•
|
When the door/tailgate is
closed, the voltage between the switch and ground should be 12 V.
|
|
•
|
The switch is grounded when the door/tailgate is opened. The voltage
between the switch and ground is then 0 V. The alarm is set off.
|
The engine hood switch is located beside the electrical distribution box in the
engine compartment and is included as a sensor for the hood. The switch is connected to the
control module (pin 16).
|
•
|
When the engine 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.
