Take the factory training and get the passwords and software.
I see so many industry wanna bee's crying Boo Hoo I can't fix it because they made it to hard. That's because you are a dinosaur and lack the education that you get when you work for a dealer.
New's flash, the day's of resistor trucks and carburators are over.
This may sound harsh but eventually the pace that technology and the safety industry is growing in the material handling market they'll be no room for the uneducated ( I couldn't follow direction so I don't work for a dealer any more) mechanic. and I look forward to it because you make the reputable techs out there look bad.
Remember when every neighborhood had a service station and that's where your father or grandfather took the car to be fixed? look around, they're disappearing because today's cars require factory training to keep them running efficiently and safely.
that's not to say I hold it against anyone wanting to strike it out on their own but don't whine when the info isn't readily available to you.

and pls don't try and tell me that you can work on cars with your aftermaket snap on or mac scanners because any factory tech will tell you that you can get stung by software incompatibility flashing the wrong code sending you in the WRONG direction.


Cheers.
