Got Stratus home today, gave it a quick wash, and played with the dizzy and still no luck. Checked the codes and found the issue: P1626...
I've tried the passlock relearn procedure but the security light never flashes, just stays on solid. Checked the fuse and it's good as well. Any ideas?

Thats how my 98 did and the module under the dash was burnt up. Replaced it and was good to go but still had blackbear tune it out.

Do you have the original remote and key to that suburban?
If passlock gets goofy enough a remote doesn't help. Bought one for our Burb last summer and it "worked " for a week or two. Then it went back to doing what it wanted. No more issues after the tune out.

I'll probably have my tuner do it. May have him adjust a couple things to just to help fuel mileage as well while he's at it. I wasnt too impressed with Black Bear the last time I used them when I originally swapped my 6.0 in. Plus I could just take it straight to him and not have to send my pcm off.

Ok jw if the truck thinks it's being tampered. Most likely the passlock, from what I've read and heard..But I know on mine if the remote doesn't turn off the alarm the key wont start it. Even if the doors are unlock and alarm not going off..
