Check out this video posted on youtube.http://www.youtube.com/watch?v=BLrnK2P9fXA
To access hidden screen, press tesla logo on top of display for 3-4seconds and a screen will pop up prompting you to input access code.
If you have the code, the hidden screen allows ability to limit car speed like the test drive cars plus a lot of other functions.
Yes, I'm sure a lot of people know it and they all work for Tesla.
I bet it's "42"
The Service Center told me it was "locked up" after someone "hacked" into it...
I doubt you'll find anyone who will share the code, and if you do, please do not publish that code in a public forum or give it out. The service menu is hidden for your own protection and you are not supposed to change any of those settings. You could brick your car, you could compromise the vehicle in some way and injure yourself or others, and Tesla's software likely logs access attempts to this feature. Chances are that if you try to access the service menu, Tesla will know about it.
Oh there's no doubt they will know about it. It's like jailbreaking your phone. You can do it but be prepared to suffer the consequences.
I found this to be the most interesting/useful image from that video:
Tesla need to feed their tech heads by giving them read only access to some of the information from these screens. Imagine how many Teslaheads would just die for an ipad or main dash screen display with some of the detailed inner workings of the drive train and other systems. would also go a long way to making people not try to jailbreak into these systems.
I want that screen as my web home page.
I think the powers-that-be are smart enough to use some form of two-factor authentication. I simple code will not work.
Go back to trying to stick you hand up the soda machine for free drinks and stop wasting my time...
