2-Speed Torque-On-Demand (TOD) Operation
WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
The automatic 4-wheel drive (A4WD) system is a 2-speed torque-on-demand (TOD) operation that utilizes the following components:
- Transfer case
- 4-wheel drive (4WD) control module (integral to the powertrain control module [PCM])
- Mode select switch (MSS)
- Gearmotor encoder assembly (part of the transfer case shift motor)
- Transfer case shift motor
- Shift motor sense plate (part of the gearmotor encoder assembly)
