My 997.1TT has been in storage for about six months on a trickle charger. Unplugged the charger, and it cranked right up. However, the PCM did not come on at all.

Fuses all checked and good.
Tested all other systems.
Able to navigate through center message center, even sport chrono working
Held down power button for various time intervals
Played with "dark" button

Any other thoughts? I know I turned it off when I stored it, and unplugged radar detector to prevent battery drain.

Thanks!

 

Nevermind ... I thought I read row C slot 9 in the fuse panel. I just went out and checked them all because I do that kind of thing, and it is row D slot 9.

Problem solved ...
