I have a 07 Chevy Tahoe and my wife drove it a few hours prior to this happening. When she went to leave again she went to start the truck and the truck started but then cut off. She went to try and start it again and it would not start. All I get when i turn the ignition is a slight delay where nothing on the dash shows except the check engine light for approx 7 seconds. Then all the dash indicators lights come on and the display reads, Service Stabilitrak, Service 4 Wheel Drive, Service Air Bag. After looking throughout the internet I come down to checking every single fuse and found none blown. I read several posts that had the same symptoms and they said it was the BCM. So I located a website that i could purchase a new BCM and they would pre-program it for me according to my vin number. Ordered the new BCM and it arrived today. I changed out the BCM and STILL having the same issue!!! Please someone help before i pull my hair out.

 

What OBDII codes is your vehicle showing?

 

Sorry for the delay I had to borrow a code reader. At first it wasn’t pulling up any codes at all, then after sitting a bit I could hear several clicks of a relay and checked the reader and found code U0073.
