I have since replaced the alteranator and the battery thinking this would solve everything and it ofcourse did not. The battery message is still displayed. It doesnt constantly stay on...comes on for about 5-10 seconds and then goes away. I have had both the new battery and the alternator checked and the computer says that they are fine. Anyone have an idea of what is up with the message?
While driving this morning, the truck seemed to stutter and wanted to stop running. The truck did continue to run, but the engine light immediately came on.
I used a Actron CP9135 diagnostic tool and received the following codes:
P0087 - Fuel Rail Pressure Too Low
P0700 - Transmission Control System Failure
Does this diagnostic system work for the duramax?
I have a 2003 GMC Sierra 1500. For Christmas my wife bought me a remote starter for my truck. It was a pretty simple installation after I deciphered the instructions. In summary, the remote starter module hooks up to a bypass module and the bypass module talks to the truck through the OBD2 port to make all the functions work. The only interface points to the vehicle are the brake switch, the OBD2 connector, and a harness that plugs into the tumbler the is turned by the key. So there isn't any wire hacking going on here. So I get it all hooked up and it's working great. Now it's time to neatly tuck everything away and put all the plastic trim back on. While doing this I realize the harness that plugs into the tumbler is going to get in the way of the bezel that goes around the ignition. Under the steering column is this sort of large metal plate that is held in place by 4 10mm nuts. It's obvious that if I remove the plate and tuck the harness under the steering column and replace the plate that everything will fit quite nicely under the dash.
How wrong I was.....
After replacing the plate the truck will no longer start. It cranks. The instrument cluster lights up. It catches but does not stay running. Power door locks, dome light, power windows, and probably other stuff also do not work. The power mirrors do work. I completely removed all the remote starter related components and plugged the original plug back into the tumbler but still all the same problems.
Can anybody help me diagnose this? I checked all the fuses that seemed relevent to any of the failing systems. At this point I'm in over my head, and I have a dead truck. I have no idea what to do.
Happy New Year and many thanks in advance for any replies.
FYI, what you're describing is called the memory seat control module.
I think I have a ground/return issue.
With lights off, turn signals cause dash gauges to fluctuate in time with the flasher.
With headlights on, dash lights go out, all gauges to to "zero" & the regular & high beams are reversed, i.e. the indicator is on high beams when they are not.
Also, I believe something is draining the battery. Connecting a multimeter at the battery reveals a .25A discharge with everything off. Only thing I can see requiring power is the radio clock & .25A (250mA) seems like more than it should be.
Any thoughts?
Thanks, John
I am wondering if i should change the computer?
I also wonder if the harness is bad?
intermitantly, when ever my parking lights are on, the gause cluster doesnt light up and all the gauges drop to zero, but at some point the temp gauge starts to slowly climb untill its pegged, i used to be able to get away with just giving the top of the dash a good pounding... now i need to buy a new dash...lol either way, let me know if you come up with a solution.... and i'll do the same
Thanks!!
The engine stuck wide open and will not idle down now. I took the fuse out for the cruise and the electronic throttle control, but it still will not idle down.
Any idea would be appreciated.
Chevy Silverado's are having a problem with this !
the low idle was a common problem on these engines. Actually, the real problem is that the accelerator is sticking (although this is not as evident as the low idle; this is why you feel the surge, instead of a smooth acceleration. The low idle is a by-product of this problem). The problem is due to hydrocarbon (sludge) buildup inside the throttle body, and possibly the air flow sensor.
It had something to do with his Key to the ignition ! It is programed to start the truck
but it was acting up, and the truck would not start. He went to the dealer and they had to get him another key, just any key will not work !
Hope this helps you ! Good Luck !
If this is not grounded good it will cause the dash gauges to act up !
Good Luck !

Maybe you would prefer to beef up your old computer !
This chip is for Chevy Silverado ! Copy and Paste the web address above and check it out !
But your warranty is only good to 70,000 miles or 7years ownership. Plus they never sent anyone a notice about the defect. Hope this helps.
Also, check your fuse for the O2 sensor, your trans is on the same fuse !
Replace it and then try out your transmission again !
Just purchased a Sierra 2500HD Classic with the Duramax diesel. The hand book refers to a number of settings that can be changed via the DIC. I do not have the buttons on the steering wheel to access these functions, does anyone know whether the same module is used in all trucks, and is there a way to add external control buttons to access the info?

New to this forum, and I'm looking for a wiring diagram for 2006 Sierra seats.
I'm not sure what options are in these electric seats... I picked the seats up out of a wreck... put them in my Willys Jeepster, now would like to make them work.
Any help and assistance would be greatly appreciated. (Printed pdf file would be superb!!
Thanks,

thanks
I was wondering if you found what the problem was on your truck. My 2006 model is doing exactly the same thing, started a few days ago. Any help would be much appreciated.
I am from GM Customer Service. I would recommend taking your vehicle to a dealership, and at least having them diagnose the problem. That way you know what you are dealing with, and figure out how to proceed from there. Thank you,

I don't want or need the big brother approach. This replaced a 1973 Chev 2500 that had two engines replaced and I knew every nook and cranny. Now I have to let the computer run certain operations but want to keep the rest private. Ideas? Thor
