robporsche Posted April 17, 2021 Report Share Posted April 17, 2021 (edited) Morning all to take the pcm unit out, is it park it in Drive then just disconnect battery, if it's in drive I can't take the key out even though the screen says remove key from ignition. I guess no harm disconnecting the battery like this Edited April 17, 2021 by robporsche Quote Link to comment Share on other sites More sharing options...

Madlil Posted April 17, 2021 Report Share Posted April 17, 2021 I didn’t disconnect the battery when removing PCM for the Joyeauto upgrade but can’t see any harm in disconnecting and leaving key in. Make sure you don’t close the frunk! Worth tying a small cloth around the latch on the frunk to prevent accidental closing. 1 Quote Link to comment Share on other sites More sharing options...
Driyage Posted April 22, 2021 Report Share Posted April 22, 2021 I didn’t bother disconnecting battery when I removed mine. moved to D, then get unit out (not disconnect) move to P, key out and disconnect Quote Link to comment Share on other sites More sharing options...
