Hello everyone, I tried to calibrate used Transfer box Torque module . I follow ISTA service function. When starting ISTA say communication whit module is OK.

But when tried to store classification number get "communication error that connection with  module is lost" I get this error message twice and after that ista say "classification number is stored successfully".  

Continue service function with calibration and ista complete whole procedure and say that is successful. But after starting engine again error massage's pop up. 

440100 (VTG): Control unit: Complete system fault 
48068C Transfer Box: Temporary fault, temperature 
48097D Transfer Box: Fault, clutch position know, no four-wheel drive 

So what can you advice me, original module and used one are both died or something I not done right?  Used ISTA 4.32 and Ista 3.47 with Enet cable.
