Why do I need a transfer case on my k1500?
The transfer case is used to provide a means of power flow to the front axle. The transfer case also provides a means of disconnecting the front axle, providing better fuel economy and quieter operation when the vehicle is driven on roads where four wheel drive is not required.
What does a GM transfer case motor do?
One is a 1999 model, the other a 2000. Both use the same controls and happen to have stored the same DTC. The basic system consists of a transfer case motor and encoder, front differential actuator, transfer case module, speed sensors, switches and park input and output to the PCM.
Why does my k1500 4 wheel drive not work?
Chevrolet K1500 4×4: 4wd does not work, no 4wd indicator light…. This is useful when difficult off road conditions are encountered. OPERATION When the Ignition Switch is in RUN and the four-wheel drive control lever is engaged, the transfer case switch closes and battery voltage is supplied across the front axle actuator.
What causes the failure of 4WD transfer case position?
Do not overlook the need to maintain a tire pressure too. Where there is even a bit of deflation in the tire, it would resist shifting from 4wd to 2wd, and vice-versa. This is one of the easiest problems to detect that leads to 4wd transfer case position sensor selector switch problems. 2. The Dirt And Water
The transfer case is used to provide a means of power flow to the front axle. The transfer case also provides a means of disconnecting the front axle, providing better fuel economy and quieter operation when the vehicle is driven on roads where four wheel drive is not required.
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.
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.
What’s the difference between GMC and Chevy transfer cases?
Chevy used a NP241C and the GMC a NP243C transfer case. That is New Process, also known as New Venture. The main difference is that the NP243 is electronic shift, but not Autotrac or all-wheel drive, it is simply a push button activated transfer case with 2HI, 4HI and 4LOW.
