I have an '05 Gallardo.
When I used to fire her up, the computer would go through the visual check of all systems on the dash then give a big OK in green.

Now when she is cranked up, the dash shows a big green OK but doesn't seem to go through all the systems that used to be displayed.
Is this some type of electrical error or maybe I somehow turned off that feature??

 

Normally, when you put the key in, it will 'chime' 5 times, and then say OK in green.

To do the on board computer check, you have to press one of the buttons below the speedo on the right.
