Pedal Monitor Warning
- Thread starter Snax
- Start date
I have that occasionally on my 2020 S. It appears transient, and does not seem to affect anything. If it were bad, you would receive a warning outside of the service function. I am not concerned at this point. Also, see this: Alerts PM_w041_dasMIA & APS_w134_appMia

I'm worrying that if service centers get too many service visits for "errors" that car owners reveal in Service, and that really aren't a concern (like a timing problem where the device is just slow to come online, but does come online OK), that a real password will be placed to block us from the Service function. I find the information in Service useful. Look at your computer's warning and error logs and you will panic.

I just noticed multiple instances of this same error in my service menu along with another error, DI_w015_immoblizer. I found a website, "Tesla Alerts Dictionary" that decodes these but doesn't really give any further insight.

Update for anyone interested... I brought my car in for service on the PMw_041 alert.
The tech and service advisor had never heard of it before and needed to research it. Service concluded that it is a 'random software occurrence' that has no know impact on the safety or operation of my Model S. The alert is specific to the DAS-driver alert systems category which controls software functionality for cameras, radar and any other driver assist sensor system. My software is up to date and nothing is missing that impacts the vehicle. This Alert can be ignored and will eventually disappear with future software updates. If anyone finds out anything different, please let me know.

I have it too but my car is a brick 
.. my autopilot ECU has been disabled so I have literally no use of anything except for driving manually, no cruise control, no auto screen brightness, no auto anything! I’ve hired a lemon lawyer as I’ve already been through 2 autopilot computers in my 2021 M3 Performance

PM MIA error, with no accompanying user-facing alerts (as in, you see them when not in service mode) is just the result of Tesla being lazy and isn't actually an error to care about.
They've just changed some autopilot messages (across the board, AP1 to present) to match the format of what's expected by the MCU for newer visualizations.... and didn't bother to update code on some other modules, such as the pedal monitor, to understand this. So it doesn't see a message it can interpret, and assumes the DAS module is borked.
Fortunately this has no impact on anything, which is why Tesla probably hasn't bothered updating the PM code.
