When communicating with a CAN bus you may find requested data such as OBD-II generates errors. This is usually due to poor shielding or incorrect termination on the CAN bus. To confirm that you have CAN bus communications problems you can use the CANgate STATS command. Use the Text window in DeLogger to enter the STATS command. A DT80 needs to be ‘connected’ to DeLogger and the Text window also needs to be ‘connected’ to the DT80. • Halt the DT80 by entering H • Click the appropriate SSDIRECT [1->] or [2->] button to connect directly to the CANgate. • Type STATS the CANgate should now display the results of the STATS command, an example is shown below. • When you have completed the task you need to exit SSDIRECT mode and enter G to start the DT80 again.
