Unless I dreamed it, I think I read somewhere that there are a number of tweaks that Lexus dealers could do to the LS400 via the diagnostic/OBD2 port. I think these were little tweaks of settings for various toys/etc, rather than the engine/etc settings.

For example, and from memory, there might have been something to do with the way the mirrors folded/etc, duration of courtesy lights, etc

Can anyone confirm?

And does anyone know if any of the Toyota/Lexus diagnostic/scanning widgets can read/alter these settings?
