Car wouldn't go into drive and SOC on dash displayed dashes. No errors displayed on MCU or dash. Pulled out TM-SPY showing 50% and 7mv max diff between modules. Total kwh capacity 71.7 kwh.
So battery looked good but car wasn't seeing it. I did a manual power off and came back to the car 10 minutes later after dropping my daughter off in the Prius.
I was a little giddy because I figured I'm finally going to get a new battery after. I'm on the original Ludicrous upgraded 81kwh battery.
Got back to the car. Opened door. Nothing would turn on. No instrument cluster. No MCU. At this point did a reset.
Everything came back up including main battery, so now drivable.
What the heck happened? Software glitch? Canbus was showing every ok and no errors in UI. never had anything like this happen before in 130K miles and 6.5 years.
