Hello, first time post. I have a 2003 Bravada that is going into AWD intermittantly. I have been trying to understand what triggers it for a few days now but no luck. I changed the ATC case oil in hopes that would clear things up.
I found a few posts about checking or changing the encoder but was really looking for a description of how it works. For example, can you manually disable it? I saw a reference to removing Fuse #8 (ATC) but that didn't do it but maybe you need to do this when it is not in AWD?
I also ran across a TB #02-04-21-008A desribing a few scenarios. Is it possible to remove the ATC encoder and motor and enable/disable AWD by mechanically turning the splines in the ATC where the motor/encoder connects?
Any help is appreciated.
