My truck has had no electronics related issues or anything similar to this or seemingly related to this. This all just happened out of the blue. . .
I drove about 25 miles to a mountain biking spot today. I used my 3rd key, the one with the small head, like from early 90's chevy trucks. As far as I know, this is just a regular key, I don't think TB's have valet mode right? So I drove up and everything seemed fine. I stored the bike on a bike rack but I opened the tailgate to unpack my gear, and re-pack my gear when I left.
As I was leaving the parking lot, the dome light was on. I made sure I hadn't turned it on, then I made sure all the doors were closed. All 5 were, and there was no message on the dash about it. But still, the light was on. So I hit the override button and drive home. Once i got home, I poked around more and here's whats happening:
- The dome light turns on and stays on. While you are driving, it's on. When you get out, it stays on until the timer shuts it off after many minutes. The override will turn it off but beyond that, nada.
- As soon as you turn the engine off, the power windows and interior lights immediately shut off, as if you have a door open. But none of the doors are open, and the dash doesn't warm me about any.
- As soon as I start driving, my TPMS starts freaking out, telling me I need to service the system. I do sometimes get "Service TPMS" messages after a half hour or more of driving, but I haven't in a while. Now it happens as soon as I turn the truck on. It's enough to make me think it's part of this malfunction.
- I cannot open my tailgate. The lock and unlock buttons on the doors work on all the rest of the doors, but they won't unlock the tailgate. Luckily my bike was on a bike rack, otherwise it would literally be stuck in my truck. Is there some emergency release for the rear gate? I am of course going on vacation in a few days and I will need to get in the back. Also, the glass won't open when you push the button.
- My key fobs don't work! They always worked fine. Now no response at all, lock or unlock, no matter how close I am to the truck.
All of this literally happened all at once. I feel like my truck's computer crashed and needs a reboot, but it reboots every time you start it up, right? Or should I try disconnecting the battery and seeing what happens? Or is this a sign of something else entirely? Could I have somehow put my truck into valet mode and now it's stuck there? Note that once I got home, I stopped using the small key and want back to my normal every day key but no change.
Some symptoms sound like the problem may simply be a door open sensor on the liftgate not working. But if that were the case, that shouldn't affect the remote locking and unlocking the doors, right? And sure wouldn't affect the TPMS!? It just makes no sense.
