Basic Function Of The Anti-Theft Alarm System

Regulation and control
The theft alarm has a central electronic control module that controls all the functions of the system.

Sensing
A number of sensors are included in the theft alarm that are connected to the alarm control module via the car's cable assembly. These sense if the car is broken into and transmit this data to the alarm control module.

Alarm signal
When the alarm is set off, this is made apparent with sound by the alarm horn sounding and/or light by all the direction indicators flashing.

3 circuit breaking
The control module also has a 3 circuit breaking function that is activated when the alarm is set off. This prevents the engine being started by immobilizing the car's starter function, fuel supply and engine control system.

Operation
Arming and disarming of the theft alarm is achieved using a remote control or the car key (programmable).

Alarm status
There is an LED in the car to show the status of the alarm. This flashes with different frequencies or is lit continuously depending on the situation.

Programming/scan tool diagnostics
The Intelligent Saab Tester (ISAT) scam tool is used for programming and scan tool diagnostics on the theft alarm.
