MCU 1 restarted on its own

[Zeeshan Javaid]

Today my MX 2016 MCU1 restarted on its own when I was driving it. Service mode shows these errors at 23:03 when it restarted.
Any idea what does it mean? Everything is working fine though.

Those don't look related to the reboot.

There's a watchdog on all versions of the MCU which reboots it if the software crashes. If it's happening often you may have a hardware fault. Otherwise rare crashes of the software are a fact of life. The AP computer can also crash, and when it does AP features will go away for about thirty seconds.

It just rebooted once in last 3 months of over 5000km driving so I guess it’s ok.
The overcurrent errors are constantly there even when car is parked but you can only see them in service mode.

Do you have a new EMMC installed (replaced since new)

The overcurrent bugs are a current software bug, there's a few other threads here about it. Apparently you can ignore them. That's why they are only visible in service mode.

How do you check if my car has new eMMC installed or not ? I bought it few months ago and it’s on MCU1

Just checked Tesla recall site with my vin and it says no recalls for this vin

Then you have the new eMMC.
