    Anyone know how to reset the PCM unit?

    Was reading about it on another board, about turning the key to the on position and holding the keylock button for 10 seconds. should the door be closed? and is the keylock the unlock button or the lock button? any clues? it also resets the learning curve of the gear shifts. is thier a sound that confirms the reset has occured? any help would be appreciated. thanks in advance.

    Re: Anyone know how to reset the PCM unit?

    Porsche Communication Management (PCM) reset? There is some button combination you can push to find out what software version the PCM is using. I missed the post about a reset for the PCM.

    There have been many posts related to resetting the cars control electronics through some button or key combination or sequence. These procedures are supposedly related to DME or transmission control unit functions though and not the audio or navigation functions. This sounds more like what you may have read.

    Some of these procedures are fairly elaborate. I have not heard of the 10 second door lock button combination but there are so many varieties it's hard to keep up. Most of these procedures contain elements of the actual throttle valve control unit (E-Gas) adapation, which should be performed any time the battery is disconnected or the DME or throttle valve are disconnected or replaced. The PAG publication, Service Information Technik, has these instructions for the procedure:
    Quote:
    To perform adaptation, switch on the ignition for 1 minute (do not start the engine and do not operate the accelerator pedal), then switch off the ignition for at least 10 minutes. The throttle valve stop (close) is readapted.



    This procedure, and it's many variations, are popular on internet forums because it is one of the few things the owner can do themselves to try and effect a cure for poor throttle response. I have tried this procedure and many of the variations you may read elsewhere but I have not found any of them to be effective.

    just press all together 2,4 and 8 (on the num pad) it's like on PC Alt-Ctrl-Del

    Thank you

    Re: Anyone know how to reset the PCM unit?

    to get the software version on the pcm you have to press main and trip .
    to reset all electronic to factory settings you have to remove battery cable for more than 10 minutes
