Transfer Case Mode Sensor Signal
The Transfer Case Mode Sensor Signal Input will provide the DTCM feedback about the position of the transfer case. The mode sensor is a linear analog position sensor with a 1.4K +/- 20% potentiometer and a 1 K +/- 20% wiper resistor that converts the motor shaft position into a multiplexed voltage. The mode sensor (on the active transfer case) is an active device where the sensor's current changes as the motor shaft position changes
