Modified ADB Function (2-Wheel drive Vehicles Equipped With MK60)
The ADB is an automatic differential lock that improves traction. The slipping wheel is braked by pressure built up in the hydraulic unit. The drive torque can be transferred to the wheel with the greater traction, which can transmit drive power to the road. This function takes the place of a limited slip differential.
The MK60 DSC III system incorporates two methods of ADB based on the DSC switch input to the control unit. With the system "on" the ADB works with engine intervention at a threshold of below 40kph (24 mph).
Tapping the DSC switch (<2.5 s) increases the slip threshold of the ADB up to approximately 70 kph (42 mph) for the purpose of increasing traction.
This feature is also helpful for example when rocking a vehicle out of mud or snow.
