I used my brother's code reader yesterday, it's a Delphi 105 and works great with my 1997 940. We used it to reset the abs light as it found the rear diff sensor was playing up. Quick clean and it's been fine.
I didn't get chance to reset the alarm control module as I forgot my uncoded fob but it looks like it can clear the memory on the control module too.
