Where is the transfer case actuator on a GMC Sierra?
The GM Genuine Original Equipment Transfer Case Actuators are electric motors that perform transfer case shifting in electronically controlled four-wheel drive systems. They are located on the outside of the four-wheel drive transfer case housing.
Where is the encoder motor on a GM transfer case?
Access to datastream information for GM’s NVG 246 system makes most problems simple to locate and diagnose, as our case studies demonstrate. These systems also allow bidirectional control for many outputs. The encoder motor (arrow) is mounted on the front of the transfer case and is used to lock it into 4WD.
How to install a transfer case 4×4 actuator?
AFTER install, hold the selector knob on the dash full turned to the right (nuetral) and turn key on. Hold 30 seconds +/- and let it go. The light will eventually indicate 4low. Work the knob slowly to each selection. Allow the light to follow. At one point I had to turn drive shaft slightly by hand to allow it to release from 4low.
What is mode control on GM transfer case?
The dash buttons to the right of the air vent identify this system as an NVG 246 automatic two-speed, which means it has DTCs and scan tool capabilities. mode control is a set of normally open switches that vary the voltage supplied by the transfer case module when closed.

Can a transfer case be changed in a 4WD truck?
The entire motor can be replaced, or just the less expensive encoder inside can be changed. The transfer case encoder motor moves the transfer case selector automatically. In Auto 4WD, it continually moves the input shaft of the transfer case to vary the amount of torque that goes to the front driveshaft.
