She's Trying To Kill Me

[MiniSimp]

Driving down the freeway at about 75mph and on a very slight left turn and the traction control light comes on and then activates! The rear tires start alternate pulse breaking and I damn near crash because of it! This has happened at least 5 times and always at the same section of highway (Sunol Grade south). I have to think there is obviously something wrong with my traction control sensor.

How can I fix this?
How can I diagnose what the problem is?
How can I disable it?

It could be a yaw rate sensor problem.  Back when I worked at Lexus we had a campain to replace those little (but very expensive) sensors.  If they weren't calibrated properly, the car would do as you described.  I would bring it to the dealer.  This doesn't sound like anything you could fix at home.  I think you can disable the system by disconnecting a wheel speed sensor to shut it down, but don't quote me on that (no liability here!).  This will undoubtedly set codes for traction control.
