FYI with the new software the parking brake can be ON even though the display does not show it as being on. That may cause confusion.In my case it was just the ECU Configuration that got updated from LK9C-14C602-DS to LK9C-14C602-DT when I updated ABS a few days ago. FDRS also downloaded the strategy (LK9C-2D053-CK) file, but my car got that back in May as part of PowerUp 4.2.6. It makes sense as both ECU Configuration revisions are meant for that strategy revision and it assures the strategy is at the right revision. It can be a little confusing if you do not keep track of the revision levels. I have a giant spreadsheet to note the part numbers of the revisions.
I noticed the Parking Brake would come on if the car was on an incline before the update and it seems to do it anytime the car is parked after the update.
Last year the tail of my MME went over an embankment after backing out of a friend's driveway on a dark night. It ended up with part of the frame resting on the ground. Fortunately another friend had a pickup truck and a rope. It would have been easier to get the car back on the road if I knew the parking brake was on. There were big ruts in the embankment from the tires. Fortunately no damage.
Since I never touched the parking brake, I did not realize it was on and did not pay attention to the driver display. I looked up how to turn off the parking brake later on, and I practiced a few times turning it off and on when I was on an incline.
