2007 Trailblazer, remote start shutdown after 10-12 seconds, recommended fix doesn't work

Question

I looked through previous questions and couldn't find the answer.......I have a 2007 Trailblazer with a Bulldog RS82 remote starter.  The INT-SL is in datalink mode and has been working perfectly for over 4 years, operating the parking lights, heated seats, rear defrost, etc.

Just the other day my vehicle started shutting down about 10 seconds after startup via remote starter.  I saw the bulletin about the false positive on the brake signal being communicated to the remote starter unit, so I tried the fix recommended there of grounding the green wire.  However, doing this only seemed to disable the security bypass as the vehicle would then just crank and crank with no ignition.  I disconnected the INT-SL and reset it several times to see if I could get any different result, but didn't.

I did isolate the issue to the INT-SL by ruling out the Bulldog unit as the problem.  I did so by letting the remote starter start the vehicle, then unplugging the 4 wire connector from the INT-SL before the 10 second shut down, and the remote starter continued to keep the vehicle running.

The INT-SL is running firmware v. 3.01.  I really don't want to have to try to hard wire into the parking lamps and lose the heated seats/rear defrost features.  Any ideas on what else may be going wrong, or how to fix it?  Please let me know.  Thanks....

I'm actually stumped considering we do list the Bulldog as a datalink compatible unit with the Fortin datalink protocol

I recommend you to reprogram the unit without doing Step 5 : INT-SL+ Install Guide

The only things you'd have to wire between remote starter and INT-SL+ are

• Lock
• Unlock Driver 1
• Trunk Release (if electric)
• Tach if not already connected.
• You do not have to wire your heated seats and mirrors as they will turn on when the temp is cold like usual.

 

Your parking lights need to be wired directly from the remote starter to the vehicles wires.

And... about the 10-12 secs shut down. This is normally a tach problem. On GM you may want to try connecting a tach directly from remote starter to the vehicle.
