BW 44-46 Transfer Case - Description

DESCRIPTION

The BW 44-46 is an electronically controlled active part-time transfer case.

The low range provides a 2.64:1 reduction ratio.

OPERATING RANGES

BW 44-46 operating ranges are:

- 2WD HI.
- 4WD Lock.
- Neutral.
- 4WD Low.

SHIFT MECHANISM

Operating ranges are selected with a dash mounted shift selector switch. The shift selector switch provides an input to the Drive Train Control Module (DTCM) to indicate the driver's desire to change operating ranges. The DTCM uses this input, along with the input from the transfer case mounted mode sensor and information from the vehicle's CAN C bus, to determine if a shift is permitted. If the DTCM decides the shift is permitted, the DTCM controls the shift motor, mounted to the exterior of the transfer case, to perform the shift.
