Small Screen Booting on Start-up?

[Big Toys]

2015 MS, the small screen is now booting up on start, more now like over the past week or so, almost every time. This is a sudden change. Impending doom?

Mine started doing this a couple of weeks ago and mine is a 2016 with only 33K miles on it.

Try clearing the trip counter and some of the navigation entrees. If it's still doing it it's probably the eMMC on the way out.

How do you clear navigation entries?

Just swipe them to the right...one at a time.

Holy cow! My 2013 Model S had nav locations stored since we bought the car! Took awhile to clear them. We'll see if that fixes the dash screen needing to boot often. It just started doing that.

See if power saving is enabled. That puts the small screen to sleep to save power at the expense of taking longer to start.

This is exactly what was causing this same issue in my 2013 S recently. Started happening much more consistently after I updated to the 2020.24.6 builds.

I noticed this after the last 2 updates as well

I noticed that behavior few months ago. Tesla implemented some algorithm which puts the IC to sleep. I noticed that it's a lot more likely to be booting up if I haven't driven the car in a couple of days, or if I get in the car late at night (after midnight). I swapped my emmc on the MCU not long ago and did a full factory reset clearing out all counters and history, so it probably is not related to aging or failing emmc on the MCU. Of course, the emmc on the IC could be dying (I assume it has one), @EV-Fixme , have you come across failed IC emmc yet?

My instrument cluster had an EMMC failure and needed to be replaced by Tesla, so it is a separate computer from the main MCU EMMC chip but going by the infrequency of people reporting it the IC doesn't fail often.

by this, do you mean a delay in the IC lighting up relative to the MCU? This is what I am seeing on my 2020 MS, especially since the 2020.28.5. Seems to me prior to this release, the two screens lit up simultaneously upon opening the door.

I disabled "power saving" and the screen boots up right away. Good so far. Thanks for you help!

I've never had power save enabled on my car, yet the IC does boot up when I get into the car sometimes (especially middle of the night, as per my comment above). I think power save affects the MCU (the big screen).
