Yes, the Bravada one piece axle shaft. My son had the same problem but couldn't find the Bravada shaft but he did find a place that makes. I forget the name of the company, but he did have to wait until they had enough orders to make a run of them.

 

A code 2 will only allow 2WD and 4LO which sounds like what you have experienced (see attached). I wonder if you needed to clear the codes after replacing the TCCM, in order to get rid of the codes and reset it. As I understand, replacing the TCCM will set a code 1. The 3-button is a gray area for me - mine is a 4-button.

 

Thanks for the input Lesmyers, I will check your attachment. I will attempt to reset codes and report back results. I will also double check at stepper motor for 5 volt reference at the 4 channels. Thank you kindly!

 

I kinda wondered if the TCCM disabled voltage on the one channel in order to limit encoder operation to 2wd and 4Lo. I have no hard facts but think it could be possible.

 

Les I did as you said, pulled 10 amp curtasy fuse, 20 amp fuse under the hood for 4wheel drive for 10 minutes. Cycled key on and off 5 times slowly. Started it. In park and drive no shift took place to 4hi. In neutral it shifted in to 4lo. But 4 hi and 4 lo buttons illuminated. I cold feel for sure it was in 4lo. Get this lol. Then shifted in neutral to 2hi. The vacuum actuator under battery released. But I can't turn front drive shaft like I allways can when in 4hi.

 

I meant 2hi.

 

Les that makes sense that the t.c.c.m may stop 5v reference to one channel at stepper motor. I just remembered, when I installed the stepper motor, I'm sure I had the transfer case shaft in 4hi. But the 3 bolts that hold the motor would not line up. I didn't want to turn the motor. From what I read it could cause damage. So had to move shaft slightly to get bolts started and tight. Along with what you said about no power to one channel as possibly a type of fail safe. Plus me needing to turn the shaft due to possible wear on shifter is possibly preventing any shift to 4 hi!

 

Starting to wonder if the amount i had to move the motor shaft confused the motor due to detent wear inside transfer case and that play or wear is causing what you said. I'm guessing I had to turn shaft 10 -15 degrees. Looking at motor hole and threads it was about half moon. To me it kinda go's together in my mind. Your thoughts?

 

On my 4 button one, encoder motor was also quite difficult to get on the shaft so bolts would line up enough to start threads. Somehow I think this is normal.

If you cant turn driveshaft with axle released, then the TC has to still be in 4WD. Can you click through all the positions with the encoder removed?
