Anyone know if it’s possible to detect the current factory alarm status on a 2008 GM truck over GMLAN (SWCAN)? There doesn’t appear to be any other way of detecting the current armed status. I’m guessing there is, but I couldn’t find it in the GMLAN bible.
Best option I can offer is to join the open garage mail list.
Check out this website for better details:
Someone just posted the existence of a tool that can help with this too.
You could use the M2 and SavvyCAN to also try to identify this.
Thanks! I will join the mailing list and ask there.
