VTM-4 Control Unit Initialization: Notes

Whenever the VTM-4 control unit is replaced, it must be initialized to make the 4WD system function. There are two methods used to initialize the VTM-4 control unit. One method is to use the Honda PGM Tester with the appropriate software plugged into the Data link Connector (DLC). The other method is to initialize the VTM-4 control unit manually.
