I have a 2500 HD with a 6.0. I have a draw on the battery at times. I pulled the IPC/DIC fuse and the draw goes down to normal. Can this be fixed by having the cluster rebuilt?

Bit of a stupid question, but, are you trying to fix a problem or did you stumble on this and think it is something that needs to be addressed?

My battery has been intermitently going dead for the last few years. At first I thought it was an old battery so I replaced the battery. I had no trouble till a few weeks ago. It went dead out of nowhere. I had it at home and when I disconnected the battery I come hear motors shutting off. I had my wife listen and she said it was in the instrument cluster. So I got my amp meter and I had two plus amp draw. Well I went to the internet and read mostly about cluster itermitent draws. So I went back pulled the IPC/DIC fuse draw went to mabe half an amp. But now the system is working again with no parasitic draw. I am tempted to send it out for repair but at the same time don't know if the would find anything to fix. So I found this site and joined and I am trying to get more input.

When you were testing the draw, how long were you testing for? I would suggest you leave it connected for 30 minutes and watch how the draw changes during that time.

Whenever you connect the battery up, it will have a certain amount of current flow to energize whatever the PCM/BCM wants. This should not last very long though.

      Still looks like a rivet to me in the pics, I don't see a nut and none of the pics show the head of the screw. But if you says so.....

      Tire psi

      Thanks for all the help so far!   I did try right from 2026 right down to 2021, and only from 2023 down lets me select the option for tire psi change, but I get the vehicle not supported error!   I'll definitely try it under Chevrolet after work today, and I'll get the sensor number from gm for my truck tire sensors. And I'll let you know if it works for me under Chevrolet!   And if that doesn't work, I'm going to guess that what @Atlas said about maybe I have a different body control module could be true!

      2010 Avalanche 5.3 not running correctly after engine swap.

      From where I'm sitting this sounds like a compatibility problem. I'm assuming the 2007 was a 900-series truck, and not an 800-series (they were sold side-by-side in dealerships that model year), since it starts and runs.   This is why I HATE post-2006 vehicles. Everything becomes a huge problem when you try to keep the thing running for longer than the manufacturer has designed it to.    I can't remember when Global-A architecture started - either '10 or '11. For your sake, you had better hope it's '11, or you're going to be spending some BIG money to correct this cluster-eff. That's something you need to find out before doing anything else. You may have several computers bricked ... but the fact that it runs tells me you MIGHT be ok here.     EDIT: Just did a quick refresher. You're screwed. This is Global-A. The 2 systems are NOT compatible in the slightest. Once you get the correct engine in there that IS compatible, you're going to need to see how many computers are locked. Absolute NIGHTMARE to straighten out, too. Your buddy might be better off cutting his losses and finding something else.   Welcome to post-2006 vehicle electronics. This is why I quit the industry, and drive nothing built after 1994. This stuff takes all the fun out of wrenching!

      True, hard to say what differences there may or may not be between Chev and GM as well as a production year or mid year part change either.    I just found it odd that under the Sierra choice on the Autel that many of the last few years of production year did not include the choice of changing the tire pressure but if that is an Autel thing or a GM thing as to why the choices were not there. Knowing what tpms sensors are on the truck should give some guidance into which choices on the tool even make sense to try as I wouldn't give up just yet with the tool but I guess he will see what if anything he comes up with if he finds out a bit more info and tries a few more things on the Autel.
