Here the steps;
1. Click on F4-Connect (left-above side), or just need to push F4 button through keyboard.
2. Choose “Transmission Type”, click on “SmartConnect” check box, then click on “Data Bus Viewer” tab.
-“Collecting J1939 data (4th Gen only)”: sometimes a technician may need to know J1939 data related to the transmission. Selecting this option, will display pertinent J1939 data on the ALLISON DOC Data Monitor view. If a session is recorded, this data will also be saved to the same file.
