Ok here is my problem, I have an 07 FJ, I did the a-trac/locker hack/ via a direct 12v. wire from the fuse box, this has worked flawlessly for almost 2 years, suddenly the a-trac wouldn't work with the locker, I redid the hack, it worked once, now the a-trac doesn't work, the dealer said I need a new master cylinder sensor that you can only buy a complete master cylinder, $1,600.
I need to know from you tech guys if there is a way to bypass this so I can run both without spending $1,600.

any help would be great,

thanks,
Tom

oh ya, It's an auto.

If it worked once after you redid the hack, maybe you have a loose or corroded connector. Maybe try rechecking them, looking closely at the pins on both the wire harness and the component sides.

I crimped & taped the hell out of it, guess I will check it again, I will try anything at this point.

thanks,

So I took the FJ to a second dealer, They were able to clear the error code that made the a-trac not work, It now works, Go figure the first dealer said I needed to replace the $1,600 master cylinder WTF@#@$%^%&*%&^^& Freakin Dealers
