1-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 1-speed torque-on-demand (TOD) transfer case modes are controlled through the vehicle message center.

The modes are:

AWD auto - torque is supplied to the front and rear driveshafts only as needed during low traction situations. AWD auto can be switched to lock by pressing the message center SETUP button; the message "AWD AUTO" will be displayed, press RESET within 4 seconds, then the message "AWD LOCKED" will be displayed.
AWD locked - torque is supplied to the front and rear driveshafts constantly and the AWD LOCK indicator will stay illuminated in the instrument cluster. This mode is not recommended for use on dry pavement or hard surfaces. AWD locked can be cancelled by pressing RESET in the message center; the message center display "AWD LOCKED" will turn off and will return to "AWD AUTO" for 4 seconds when the transfer case clutch disengages.

If the transfer case begins to overheat, the system will default to the Autolock mode. The AWD LOCKED indicator light will illuminate in the instrument cluster and the message center will display "AWD DISABLED". Then the message center will display "AWD LOCKED" for 4 seconds and a warning chime will sound. This condition may clear without any action being taken by the driver. The AWD LOCKED indicator light in the instrument cluster will turn off when the system cools down.

When the system is sufficiently cooled down, the message center will display "AWD AUTO RESTORED" for 4 seconds and a warning chime will sound.

When a problem is detected in the AWD system, the AWD LOCKED indicator in the instrument cluster will flash 8 times every 2 minutes. The message center will then display AWD DISABLED for 4 seconds and a warning chime will sound. The warning displays and the chime will continue until the message center RESET button is pressed (which will clear the message).

If the system is not functional, the AWD LOCKED indicator light in the instrument cluster will flash 10 times every 2 minutes, the message center will display "CHECK AWD" and a warning chime will sound.
