Diagnosis


The theft alarm control module communicates with the ISAT scan tool via pin 19. The communication is two-way and as such is both input and output signal.

ISAT is able to communicate with the anti-theft alarm with the ignition "ON" (+15) but communication is normally with the ignition "OFF".

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