Automatic Transfer Case The single speed automatic transfer case system shifts automatically from rear wheel drive to four wheel drive when the transfer case shift control module (TCSCM) senses the difference in rotation speed of the front propeller shaft and the rear propeller shaft. Two vehicle speed sensors, one located at the rear output shaft area of the transfer case, and the other, located at the front output shaft area of the transfer case, send front and rear propeller shaft rotation speed information to the TCSCM. When the front and rear output shaft rotations remain the same, the TCSCM sends pulse width modulation signals to the encoder/motor to keep the transfer case in rear wheel drive. When the front and rear output shafts rotations are different, the shift control module sends pulse width modulation signals to the encoder/motor to engage the transfer case into four wheel drive. The system will automatically transfer a percentage of torque to either the front or rear axles as required to stop all wheel slip.
When the front and rear output shafts rotations return to the same speed rotation, the shift control module sends pulse width modulation signals to the encoder/motor to position the transfer case back into rear wheel drive. When the transfer case is engaged into four wheel drive, a lamp indicator on the instrument cluster will light. The automatic transfer case system is completely automated, no transfer case control button switching system is required. Do you know what DTC'S - diagnostic trouble code's are?

It would also have the vehicle control modules checked for DTC'S - diagnostic trouble codes! Doing electrical testing of the circuits of the thing's not working etc. Is the way to find the problem. It takes years to learn how to do electrical test correctly.
Someone who has no clue shouldn't even try. Answered on Jun 12, 2017. Where do you have the switch off or auto? Turn them off! 2 Use the scan tool in order to read the body control module (BCM) current trouble codes. Is DTC B2575, B2577, or B2600 set as a current code?
