what is FDII?
Freedom-Drive II™ - FDII
An electronically controlled coupling, which is attached to the rear differential, is the heart of the Freedom Drive II system. The electronic control module processes signals from the wheel speed sensors and the accelerator pedal to determine how much torque to transfer to the rear wheels, then sends an electrical current to the ECC that is proportional to the amount of torque required. Recommended for true off-road situations including steep grades, wheel lift and rock or log climbing, the Freedom Drive II Off-Road Package includes a second-generation continuously variable transaxle with a 19:1 crawl ratio (CVT2L) that engages when the off-road mode is activated.
This package includes:
140-Amp Alternator
Engine Oil Cooler
Trailer Tow Wiring Harness
Full-Size Spare Tire
4-Wheel Drive Off-Road Mode
All Season Front and Rear Floor Mats
Brake Lock Differential
Fuel Tank Skid Plate Shield
Goodyear® Brand Tires
Hill Descent Control - Can suck at times
Hill Start Assist
P215/65R17 OWL All Terrain Tires - They suck
Tow Hooks
"Trail Rated" ™ Badge
Transmission / Engine Oil Pan Skid Plate
How the ESP Works-
FOUR WHEEL DRIVE OPERATION
This feature provides full time, on-demand, Four Wheel Drive (4WD). Where one or more wheels have wheel spin or if additional traction is needed in sand, deep snow, or loose traction surfaces, activate the 4WD LOCK switch by pulling up once and releasing. This locks the center coupling allowing more torque to be sent to the rear wheels. The amber "4WD Indicator Light” will come on in the cluster. This can be done on the fly, at any vehicle speed.
To deactivate, simply pull on the switch one more time. The "4WD Indicator Light” will then go out.
NOTE: Refer to ”ESP (Electronic Stability Program) in the “Electronic Brake Control System” section of this manual for additional information.
ESP 4WD Operating Modes - 4WD Models Only
All 4WD equipped vehicles can also choose the following ESP operating modes:
ESP ON
This is the normal operating mode for ESP. Whenever the vehicle is started the ESP system will be in this mode. This mode should be used for almost all driving situations. ESP should only be turned to “Partial Off” or “ESP Off” for specific reasons as noted below.
PARTIAL ESP
This mode is entered by momentarily depressing the “ESP Control Switch”. When in “Partial Off” mode, the TCS portion of ESP, except for the “limited slip” feature described in the TCS section, has been disabled and the “ESP/TCS Indicator Light” will be illuminated. All other stability features of ESP function normally, with the exception of engine power reduction. This mode is intended to be used if the vehicle is in deep snow, sand or gravel conditions and more wheel spin than ESP would normally allow is required to gain traction. To turn ESP on again, momentarily depress the “ESP Control Switch”. This will restore the normal “ESP On” mode of operation.
ESP OFF
This mode is intended for off-highway or off-road use when ESP stability features could inhibit vehicle maneuverability due to trail conditions. This mode is entered by depressing and holding the “ESP Control Switch” for 5 seconds when the vehicle is stopped and the engine is running. After 5 seconds, the “ESP/TCS Indicator Light” will illuminate and the “ESP Off” message will appear in the odometer. Press and release the trip odometer button located on the instrument cluster to clear this message. In this mode, ESP and TCS, except for the “limited slip” feature described in the TCS section, are turned off until the vehicle reaches a speed of 35 mph (56 km/h).
At 35 mph (56 km/h) the normal ESP stability function returns with the exception of engine power reduction. TCS remains off. When the vehicle speed drops below 30 mph (48 km/h) the ESP system shuts off. ESP is off at low vehicle speeds so that it will not interfere with off-road driving but ESP function returns to provide the stability feature at speeds above 35 mph (56 km/h).
The “ESP/TCS Indicator Light” will always be illuminated when ESP is off. To turn ESP on again, momentarily depress the “ESP Control Switch”. This will restore the normal “ESP On” mode of operation.
WARNING!
In the Partial ESP mode, the engine torque reduction and stability features are desensitized. Therefore, the enhanced vehicle stability offered by ESP is unavailable.
NOTE: To improve the vehicle’s traction when driving with snow chains, or starting off in deep snow, sand or gravel, it may be desirable to switch to the “Partial Off” mode by pressing the ESP switch. Once the situation requiring ESP to be switched to the “Partial Off” mode is overcome, turn ESP back on by momentarily depressing the “ESP Control Switch”. This may be done while the vehicle is in motion.
I hope that answers your question. It is just the version of transmission I have compared to the FDI and manual.
