The electronic rear differential has the same functionality as the open rear differential but incorporates a locking feature.  
 
An electronically controlled multi-plate clutch provides a rear differential lock and torque biasing function to give improved 
traction performance and vehicle dynamic stability.  
 
A strategy, to electronically control the rear differential multi-plate clutch assembly, has been developed to provide:  
 

l

a pre-loading function, increasing locking torque with increased driving torque  

l

a slip controller to increase locking torque under off-road conditions and decrease locking torque for optimum 
comfort, e.g. parking.  

The unit receives a torque input from the transfer box output shaft, which is passed through the unit to two outputs for the 
rear drive halfshafts.  
 
The unit detects wheel slip via various vehicle system inputs to the electronic rear differential control module and locks the 
differential accordingly.
