the dreaded “alarm randomly going off” issue on my 2003 9-3



to diagnose and/or disable the alarm


Considering the following:

I also have a 2004 9-5. I’m starting tho think that it would be wise to invest in a tech2. as I usually do most of my own repairs.



Is there some other Saab-specific card or software I need on top of this product?


Suggestion from folks:

You will need the Tech 2 and Saab 32MB card (specify when buying clone) listed in the link above. Those two alone should be able to read DTCs, I believe. To get security access and make changes via Tech 2, you will need an older Windows XP laptop with built in serial port – a newer computer running a virtual machine program & serial to usb adapter should also work – and the Tis2000/GlobalTIS software.

Personal opinion: The Tech 2 in the link you posted is priced a bit higher than most ($349 vs $319). You might want to read back a few pages in this thread for some links to other sellers with better pricing and more sales.

My GM Tech2 scanner hq clone is paid for $319. It is with with a 32MB card and TIS2000 software CD.


Eidt: Tech II review:
