Hey. My Model S 2013 with MCU2 is tottally dead. It starts with turning off the esp and regen braking while driving. Next the car turned off the abs and power steering. It disappeared for a moment after charging at home, but when I started to drive just after few meters it came back. Then I tried to reboot it with the scrolls and it didn’t help. Tried to reboot by turning off with the turn off button on the screen for few minutes, didn’t help. Then I decided to restore factory settings. It didn’t helped, alerts are still there, it was a problem with parking brake for a moment, but it released it after around 2 minutes. Then tried to go reverse around 20 meters, when I stopped, it used parking brake forever and I can’t go anywhere cause it’s fighting with the rear brakes. When I tried to go forward slowly and open the driver’s door it showed me PRND on red color and PRND stopped working. After that I unplugged the 12v, charged it for 30 minutes. When I plugged it, the driver’s display stopped working too and still can’t use PRND. I can’t even turn off the vehicle on the screen, this option is frozen. Now I removed the parking brakes just to come back to the garage. I unplugged the 12v just to turn off the vehicle, because it was still using the front lights. I don’t know what to do. I did the photo of the alerts before I did factory reset. Tesla Service can take it on May, I know that I could make it much worse that it was before I touched anything, but if anyone could tell me something I could do it would be great. Regards.

Tesla Model S 2013 MCU2 PROBLEM

I checked 12v battery today. It was 12.75V unplugged. After I plug it there was 14.8V, alerts are gone, driver’s screen came back, PRND on white and it was possible to drive, only GTW_w182, probably cause of the parking brakes unplugged. I plugged the brakes and when I get in to try to drive, driver’s screen was black and I could’t drive, there was many of the alerts again. Then check the 12v battery, it was 13.8V. I unplugged it to turn off screen and front lights. What should I do?
I change the 12v battery today. When I plug everything it started for a while with the dashboard and PRND was working. It was ready to drive, after a while or if I get out and get back in it didn’t want to shift P. I checked grounding in 2 places on the front left and front right. When I plugged it again dashboard and PRND were dead. It seems that it’s good only for few minutes when I plug 12v battery after at least few hours break. I had a problem with ptcheater and it’s on the alerts on service mode too, but is that possible that it doesn’t want to drive cause of the ptcheater?

Not sure what ptcheater is. Did you recheck the battery voltage? Maybe the DC-DC inverter is dead and not charging the 12v battery?

According to a previous thread on gtw182 it's a bad parking sensor or wiring in the front bumper .

Thread says objects hitting bumper can damage the sensors or wiring. Sometimes it's rodent damage on either bumper wiring.

The code may be from the system being told the car is too close to something by the malfunction.

This is why 2013 and older models shouldn’t upgrade to mcu2, I have noticed this upgrade either messes up the battery, or issues like this happen

It’s my hypothesis but I seen so many posts on people saying that after their mcu2 upgrade on older model s they are having issues

I definitely notice mcu2 has more problems with older models. Drains battery faster and all
