this is what i found
FLASHES TRIGGER INPUT
2 Optional sensors
3 Doors (-)
4 Boot/bonnet
5 Doors (+)
6 Ultrasonic sensors
7 Ignition
say for instance your alarm goes off, you disarm it and the indicators flash 6 times, this means that something inside has triggered the ultrasonics sensors (anything from objects hanging from you rear view mirror). Etc
also when you arm or disarm the alarm do your indicators flash?
hope that helps
