Convertible Top Calibration?

[ralundy]

How do you know if the convertible top needs to be calibrated? My 996 (1999) top closes perfectly but the top indicator light no longer goes out and the window up operation is not performed. I can hear a relay clicking when you would expect the windows to be going up. Durametric shows no fault codes. Thanks in advance if you have any information about this!

The only way I know id to plug in a PST2 (or PIWIS) and then see if it offers to calibrate the top.

Make sure the plastic cover that surrounds the metal hook on the closing mechanism is still glued to the hook. If the top over stresses, the plastic cover is designed to detach, and it won't activate the micro-switch. That would make the windows not function correctly, and the light would stay on.

If that is the case, you should be able to push up on the plastic cover (after it has retracted... don't lose a finger) and activate the micro switch. That should allow the windows to activate. You will then need to get the top calibrated, and a new plastic cover for the hook.

This problem is very common in colder environments, if you put the top up while it is too cold. The canvas and plastic window shrink slightly in the cold weather, and can make the top too tight to fully deploy safely.

It is probably the microswitch...Try unplugging and plugging it in again (see the smarttop installation instructions). I had a stealer "calibrate" the top...don't think it did anything to be honest.
