Driver Control Center Differential (DCCD)
(WRX STI only)
This electronically controlled system
adjusts the power-distribution ratio
between the front and rear wheels.
The system is designed to provide
optimum differential control for
improved vehicle cornering, stability,
and handling control to suit driving and
road surface conditions. The DCCD
can be operated automatically or
manually. When the system is in the
automatic mode, the “AUTO” indicator
light in the combination meter comes
on. The DCCD can be taken out of
“AUTO” mode and used manually by
pressing the “AUTO MANU” switch
located on the center console. Use the
DCCD control switch located on the
center console for manual operation. Pressing the “AUTO MANU” switch
again will return the system to “AUTO”
mode. When using the system
manually, if the control switch is set
closer to or at the “Lock” position,
the powertrain may make a vibration
or noise when the vehicle is in tight
turns at slow speeds (system binding).
In addition, if the rear differential
oil exceeds a certain temperature,
the DCCD will automatically cancel
the current torque-distribution ratio
setting and adopt its minimum ratio.
