Dead Battery with Trinity - 03 Sierra

[Callbeck1]

I just recently got a 2003 Sierra 2500 hd with 6.0L. Mine too kills the battery overnight. I have found that it only does this when left in monitoring. If I exit monitoring first then leave the truck the battery is fine.

I too have a 2003 2500HD with the 6.0. I have the same problem and I also have a running post under the 2006 post above. So far no one has come up with any answers and it has been well over a month with mine. I even wasted my money buying a new battery for my truck. I can max the sleep mode to 60 sec and it will still run the battery dead in 3 days.

I think that they forgot about us and moved on to modern car problems! Must be a lot of issues with these tuners. I have one that I can't use for what I paid for because it will drain the battery in 2 days. What a POS! You won't ever get any more of my money you theives.

I have attempted to duplicate this on my 99 Camaro, with no luck.

If anyone is local with this issue, please get in touch with me.

Thanks

I maybe supid but how is a '99 Camero the same as a 2003 GMC 2500HD?

they're both GM Class-2 vehicles... same vehicle class, same communications protocols, etc...

So do you have any suggestions? My $100 Scan gaugeII monitors just about everything the Diablo does and doesn't kill the battery.

Mine is doing the same thing! O3 GMC sierra 2500 8.1 liter With the Trinity unplugged the battery will not die. I am now trying the 30 second thing! See what happens!
