ST955i - Datatool system 3 - battery reconnect - permanent alarm


I had my battery disconnected from my 04 955i ST for a year. On reconnection the datatool S3 goes off and the fob has no effect on it. The alarm sounds for about 30 seconds and then rests and then goes off again.

I am trying to follow the "de-spiking" procedure shown on Datatool's web-site. The trouble is the procedure says things like 'disconnect the pcb from the loom'. Without using wire-cutters this seems to be totally impossible. The majority of the wires come out of the alarm unit and go into a sealed box that has no apparent way of getting into it (save using a saw). The alarm was fitted by the main dealer from whom I purchased the bike brand new.

The best I could do was take the internal battery jumper out and disconnect a single 3 wire plug. I won't know whether this will have the desired effect until I have waited at least 6 hours for the internal battery to discharge.

Has anyone had any success with the de-spiking procedure? or has anyone got an alternative suggestion (please refrain from saying throw the alarm away - I know it will be a strong temptation but I am holding this alternative in reserve for now).

Many thanks

Whoever installed it is a moron if they hard-wired it - there is plug n play harness/connector for Datatool on Triumph - all modern Triumphs for at least 15 years have come with a pre-wired Alam interface connector.

Did you check battery in the fob?
