I'm newbie to Autel but very well versed in automotive electronics.
I have a NP246 4 button Automatic Transfer Case and have checked that the Transfer case fuse is good. All other ECM and TCM data and control working fine with MaxiDas 708, ( Last revision being 2013)
I get the "Not Communicating with ..." display. I have checked all the suggestions but to no avail.work.
Tried many settings but this is what should work when I go to Data Display - ATC
Selected GM v7.00
1998
LD truck
Power Train J 7.4
Chassis K 4 speed automatic without airpump
When I go to Data Display - ATC
I get the "Not Communicating with ..." display. I have checked all the suggestions but to avail.
[Also if I skip the ATC data and go to special features it acts like it is communicating and brings up the control display screen but actually nothing is working.]
I have a Blue Driver tool and it can communicate and read TCCM. I have replaced the shifter motor and encoder and want to calibrate the new part.
