993 alarm / central locking gremlins

[911cedric]

Hello All,

my 993 4s has developed an annoying bug

The central locking doesn't work anymore; the locking button on the central console doesn't lock the car, closing the doors manually doesn't trigger the central locking on each door anymore, the remote doesn't lock and unlock the car anymore and the door lights do not work anymore when the doors are open

The alarm red LED is continuously on if a door is open; it will only switch off when both doors are closed

Fortunately, the remote still disable the immobilizer when i push the button.

Oh, and on top of that, the immobilizer likes to suddenly shut down the car while i'm driving, which is as you may imagine dangerous and embarrassing

Do you guys have any idea before i plug the PST2 and spend hours figuring out what's the problem?

Thanks
Cheers
