Diagnostics

The anti-theft alarm control module communicates with the Intelligent Saab Tester (ISAT) scan tool via pin 19. Communication is two-way and as such consists of both input and output signals.

The ISAT scan tool can communicate with the theft alarm when the ignition is in the "ON" position (+15), but communication normally takes place with the ignition "OFF".

Communication between the ISAT scan tool and the anti-theft alarm is not possible if the alarm is armed.
