REAL TIME AWD CONTROL UNIT INITIALIZATION  
PROCEDURE  
NOTE:  


Whenever the real time AWD control unit is replaced, it must be initialized.  
Park the vehicle on a flat and level surface.  
1. HDS DLC - Connection  
1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the  
dashboard.  
2. Turn the ignition switch to ON (II).  
3. Make sure the HDS communicates with the vehicle. If it does not communicate, go to the DLC  
circuit troubleshooting.
