So I got this 4x4 inactive message, followed by 4x4 light, abs light, and brake light in red. It seems to reset itself after a while, and is usually gone when I first start to drive it. It returns after about 20 miles of driving. Sometimes more often.

I hear a funny, click click click, followed by what sounds like a winding noise when I turn the car off. Like something just disconnected and spun.

I am feeling that it could be the actuator. Can anyone point me in the direction of its location?

Also going to try to get my hands on a GT1 for further diagnosis, hopefully it is something as simple as all of my fixes have been.

Anything else I should check? Battery seems fine.

POST 13 is the solution. 04/01/2016, actuator flip still going strong.
