2015 S Park Assist Unavailable

[muitec]

I had this message popped up 5-6 months ago and I powered off the car, turned it back on 30 minutes later and the message is gone. But now it came back on and the power off method not working. I checked the bumpers sensors in service mode and they’re all Green.
Do I need Park Assist? Probably not but can I drive the car with this message on the screen all the time? It’s just annoying.

The wheel configuration reset is better. Have you looked at the sensors? Is one crooked or loose?

All the sensors look fine. No crooked no loose.
How you do the wheel configuration reset?
The 2nd picture indicated that the PARK sensor S4 shorted battery, which is sensor S4?

How old is the 12v battery?
Wheel config: on service page, wheel configuration, change to a different size, confirm, let the reset happen.
Change back to the correct size and wheel, confirm.

Wheels are original from factory and have never been changed. 12V battery is around 3 years old.

The 12v could be getting weak, it should be checked.
The wheel configuration reset is on YouTube.

Did the wheel configuration NO HELP.
Removed the S4 sensor from front bumper and cleaned it with electronic contact cleaner but didn’t help either. Probably need to get a new sensor.

If you put the car in drive and have someone check the sensors for vibration then you can confirm that only #4 is out.

If your car has a nosecone then it's easy to remove it to check the sensor plug is not loose.

Weird! The problem disappeared this afternoon. Hopefully it won’t come back LOL

Weird things happen when the 12v starts to quit. It should be checked when the car has been asleep and not being charged by the system. The voltage should come up when you open a door or sit in the drivers seat.

Tesla replaced my 12V battery but message still shows up. Seems to me that when the weather’s above 60 degrees it works fine but if it’s dropped below 60 degrees that when it popped up and as soon as above 60 it’s disappeared

I had this issue and just needed to replace the sensor harness, years of being exposed to the elements made the cable brittle and caused loose connections. I did try soldering the parts I thought were the issue, but I ended up having to take it in and get that harness swapped. Was around $250 for parts and labor
