Four Wheel Drive (4WD) Systems
Four Wheel Drive (4WD) SystemsAll Wheel Drive (AWD)
The all wheel drive (AWD) system utilizes these components:
^ Transfer case
^ Differential (internal to the transfer case)
1-Speed Torque-On-Demand (TOD)
The one-speed torque-on-demand (TOD) system utilizes these components:
^ Transfer case
^ Electromagnetic clutch (internal to the transfer case)
^ Four-wheel drive (4WD) control module
^ Message center
2-Speed Torque-On-Demand (TOD)
The automatic 4-wheel drive (A4WD) system is a 2-speed torque-on-demand (TOD) design that utilizes these components:
^ Transfer case
^ Electromagnetic clutch (internal to the transfer case)
^ Four wheel drive (4WD) control module
^ Mode select switch (MSS)
^ Transfer case shift motor
^ Encoder assembly (part of the transfer case shift motor)
^ Shift motor sense plate (part of the encoder assembly)
