Trouble code P1682

[OR VietVet]

no the tune is loaded thru the obd port with a hand held programmer, it wouldn't have anything to do with the ignition circuit problem

I knew it was done thru the OBD port but I thought maybe other places like the fuse box was involved as well. Live and learn. I preach basics all the time so I recommended rechecking the previous work just done and forgot about checking the battery. That is as basic as it gets.

when you load a canned tune the device just plugs into the obd port, then you turn the key to run, load the tune, turn the key off, done!

Sir, your input is well appreciated!

Thank you again, and thank you for your service!

Changed the battery. Now to wait and see. Start-up feels way better to begin with.

Yep, always like that new battery faster engine cranking feeling. Hope this fixes your concerns.

The Tahoe is also due for a battery, so I'll make sure that is also taken care of.

This was my first thought, change it before bothering with anything else.
