2007 Suburban shut off while driving

[danwcope]

My wife was driving our 2007 Suburban (5.3L) at highway speeds when it just shut off.

 

She coasted to the side of the road assuming she ran out of gas (even though miles to empty estimate was 90). I put two gallons in and went to start it, but it won't crank -- doesn't click or anything. Thought it might be the battery, but jumping it doesn't change anything.

 

Horn and exterior lights work, but the electronics are out of whack...check engine and stabilitrak lights are lit. Warnings about 4x4 other items needing services, etc. Interior lights don't work but the front two windows work (not the rears though). Heated seat lights will come on, but faint.

 

I tried disconnecting the battery for 15 minutes and reconnecting, no change.

 

There was some corrosion on the terminals that I'm going to clean up now.

 

Anything else to check?

 

Thanks in advance,

Dan

Load test the battery or swap it with a known good one. Best place to start.

Only code was p1682. But I scanned it after I disconnected the battery for 15 min.

 

I saw service note stating that it could be caused by low voltage....

 

The anti-theft light does not stay lit or flash...
