Default 2001 blazer-4wd-code u1026
Hello all. I have a 2001 chevy blazer with 4 button 4wd. I just had my transmission rebuilt. After getting my truck back the 4 wheel drive lights on the dash all come on. Then, the Service 4wd light comes on. Then they all turn off. This happens every few seconds. If this happens while driving, my truck seems to loose all power...not electrical, but I have the gas pedal all the way down & I can't get over 30 mph. I scanned for codes and am getting U1026 - Lost Communications With Transfer Case Control Module (TCCM). I disconnected the electrical of the 4wd right where it connects at the transfer case & the truck runs fine. Any suggestions?

Try pulling your TCCM fuse for 30 minutes to reset it.
Just realized this thread is over a year old. Back from the dead.
