Instrument Cluster failure issue (does not turn on and stays blank / dark)

Does holding volume button down just reboots the system vs a reset?

Correct. It just restarts the PCM without changing any settings.

Does holding volume button down just reboots the system vs a reset?

so got in the car this morning:

• started it as normal
• instrument dash functioning fine
• took me a few minutes to notice that the center screen & passenger display was "black"
• touching the screen made "blip" sounds - but no display
• shifting into reverse (when I got to where I was going) showed backup camera display as normal on center screen
• shifting into park screens went back to black
• opened the door and got the "getting out car Lock Screen" for 1/4 of a second
• locked the car and walked away for a few minutes
• came back to vehicle and got back in - center screen and passenger screen show "boot up logos" - take a while
• drop to black after boot logos

the volume button recovered both of the screens in less than 30 seconds (almost the moment I touched it) so I don't think I actually reset anything…

but I'm glad it's recovered - the driving instrument display was 100% functional the entire time

strange set of problems…

gotta love software.

I used the "hold the volume button for 15 seconds" method to reset and fix my blank central display. It's only been a few days, but did fix it in the moment. Symptoms were like the OPs, except it was limited to the central display and not the instrument cluster. My back up cam also kept working during this, so I guess the safety displays are on a different system.
