"Hood open" sensor warning and the car will not start and OBDII reading gives Error

First, from looking up the TCM part. This has me concerned:

"Transmission Control Module: Requires Programming After Installation, Module Must Be Programmed With Original Manufacturer Software"

I do not have OM software.

My second thought, that I'd like your opinion on, is what about the Transmission Control Solenoid? I've seen more than a few online videos and other threads that this is the solution to being stuck in park.

I also saw some articles about voltage going through the Headlight Dimmer Switch. What are your thoughts on that being a point of failure for the voltage codes?

My current goal is to get it drivable so I can take it someplace (Carmax, etc.) And sell it. From my inquiries so far, I'll get far less if the buyer has to come get it and tow/flatbed it away. Probably about $1,000.00 difference. From there, I suspect they'll work on it (beyond my capability) and then resell it. It's got a good engine for 160,000 and the brakes are not that old, etc.

Also, the Hood Open "CEL" is now intermittent. Upon every shutdown/restart, sometimes it's there, sometimes it's not. :-/

Joe,

Also, if it's the TCM, I have to draw the $-line there. Those appears to be about $500+.

Joe,

I'd like to try to get to the Shift Solenoid. Do you have any diagrams (or procedures) to assist me in getting there?

Dan

Joe,

I was referring to the Shift Interlock Solenoid. Here is Rock Auto's link to it:

There are also YouTube video of others who are stuck in park and this $27 part was the cause for some. I'd be guessing if it were not for my new Autel scanner. I believe the solenoid is located, essentially, on or near the shifter column but I do not know how to get the center console out to get to it, or even how to pop 'anything' off to use a screwdriver (like others have) to manually test it, but I believe in my new tool, the Autel Mk808.

Here's one video: https://www.youtube.com/watch?v=F0zUYNcd_0k
Start at 4'48". This vehicle in the video indicates active/inactive. Mine indicates on/off, except mine says, "on" regardless if I'm depressing the brake peddle or not see attached picture). At least for getting the vehicle out of park, I now believe it's the Shift Interlock Solenoid.

Any guidance you can provide in getting the center console off and getting to the shift column would be appreciated.

I have a 2014 Chevy Traverse AWD almost identical problems. Hood Open, Can’t control the headlights, they are just on and won’t highbeam or shut off. Zero from the AC or Heat. Rear liftgate non operable. Door locks are super weird. No response to steering wheel controls. Stuck in park. I put 12v power to the lock solenoid and it released. As of now I left passenger side center console cover off and can manually depress solenoid to move the vehicle around. No hazards. No blinkers. Disconnected battery to replace power steering pump. Then all this started at once. Battery is fully charged. Vehicle starts fine. Drives fine. I have tested every electrical circuit in the vehicle at least 3 times now. It’s been about 20 years since I got whooped by a vehicle especially concerning an electrical issue of some mysterious origin. I’m about to lose my mind here. Literally. I have dismantled the entire vehicle twice now. Help please!
