TRANSFER CASE RANGE SELECT SWITCH INPUT (NEUTRAL & 4HI/4LO SELECT SWITCH)
The FDCM will support circuitry which interfaces to the system's Transfer Case Range Select Switch, including a Transfer Case Range Select Switch
voltage supply and a Transfer Case Range Select Switch input. The purpose of this circuitry is to determine the mode currently being requested by the
operator via the resistance ladder network in the shifter assembly, where the Transfer Case Range Select Switch is packaged.
The NEUTRAL Select Switch Input will provide the operator with the ability to place the Transfer Case in Neutral. The 4HI/ 4LO Select Switch Input
will provide the operator with the ability to place the transfer case in 4HI or 4LO. The NEUTRAL Select Switch is a momentary contact switch and the
4HI/4LO Select Switch is a 2-position toggle or a momentary contact switch and both these switches are provided through a resistor network for
diagnostic purposes. The input will have an internal 1.0K ± 1% pull-down resistor to ground.
As the selected position in the 4HI/4LO Switch varies and/or the NEUTRAL Switch is depressed or not, the resistance between the module's Transfer
Case Range Select Switches voltage supply and Transfer Case Range Select Switches input will vary. Hardware, software, and calibrations within the
FDCM will be provided that interpret the external resistance between the module's Transfer Case Range Select Switches voltage supply and Transfer
Case Range Select Switches inputs as given in the table:
NOTE: There is no requirement for the FDCM to distinguish between a neutral request from the 4LO or the 4HI position. Resistances in these ranges
will be represented as a Neutral Switch Activation.
TRANSFER CASE MODE SENSOR SIGNAL
The Transfer Case Mode Sensor Signal Input will provide the FDCM feedback about the position of the transfer case. The mode sensor will be 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.
