PSA

PCM 6.0 in the 992 uses the same “two finger” salute on the top right hand corner of the main screen, having just come from a 2020 Taycan I was frequently having to unfreeze my PCM so I was (un?) pleasantly happy to see the same easy reset.

 

In case it comes up... how is the reset done?

 

What exactly is “engineering mode”?

 

Use two fingers and touch the screen in the top right hand corner for 2-3 seconds, this mode is used by technicians to allow usb stick changes or updates, but it also allows us to reboot a stalled or otherwise not acting normal PCM.

 

muchas gracias.

 

Is there a way to get in there and reset service lights?

 

I don't think you can reset service lights there. I browsed through it and it shows lots of crypto data, but I didn't see anything to reset service lights.

 

Do you loose any settings when you do this?

 

I did not, but I didn't change anything. I went in, looked around and use the Exit to get out.

 

My PCM 6 was locked on the screen that said PORSCHE . I followed the dealer’s recommendation and shut the car off locked it with the windows up for 30 minutes. Worked perfectly. I first tried with one window slightly open and it did not work but closing the windows and locking worked. Go figure!

 

+1. Thanks for sharing. It is a method of restarting the PCM similar to rebooting your laptop. Locking the car with windows up tells the ECU that you intend to leave the car unattended for an extended period. The ECU kills electricity to unnecessary components such as PCM (except the alarm) to reduce battery discharge. So, when you later unlock and start the car, the PCM restarts. This is much easier than pulling a battery lead to restart the PCM.
