Default Moonroof Up/Down and Open/Close performing same action

Just picked up an 06 GS430 with 72k miles over the weekend, Just noticed that Pressing Up/Down or Open/Close does same thing.

Meaning If Moonroof is completely closed and by Pressing Close it actually TILTS up the moonroof.
Logically it shouldn't do anything once its closed...Unless Up is pressed.

or
If Moonroof is Tilted up and If Down is pressed...It actually tilts the moonroof down which is good however, it continues to open the Moonroof.

Let me know if anyone else has experienced this? or is there a way to reset the Moonroof ECU or can the configuration be changed?

There is an easy way to reset the sunroof. I had to do it, but forget how its done.
Do you have a manual? It will tell you in the manual.

I just reprogrammed my moonroof. Had to disconnect the battery today and lost the one-touch. This is how I did it:
1- Key on, engine not running.
2- Push and Hold the "UP" button and let the moonroof cycle through, Vent-Close-Full Open-then Close.

After that, everything works!

This was the ticket. When I bought my car a month ago. It was just like the op described and I thought this was the most ridiculous thing Lexus did to 3gs models but I was wrong Lol

The dealers must love these small reinitializations that need to be done whenever the battery dies or is disconnected. Nobody ever seems to know about it.

you shouldn't drive crazy, you might kill someone.

best not to disconnect it. Even a dead battery still have some juice to power the 'sleeping' part. (sorry to use a kid terminology but I can't come up with the correct term at the moment.)
