If the problem occurs with a ELM chip based interface, it is due to a wrong configuration:

• Select in the menu: OBD interface->Preferences
• In OBD interface select ELM interface and Automatic OBD search
• In Communication port select Use a serial port, scroll to the appropriate port in the list (refer to the port used by your ELM in the Device Manager) and set the speed up to 115200 - progressively reduce the speed if the connection is impossible (57600, 38400, etc…)

If you still cannot connect to the interface or to the vehicle, send us a connection log. We will try to figure out your problem. To do so:

• Click on OBD interface->Preferences in the OBDuCAN software menu
• Tick the Log on the communications box and fill the log file destination folder out
• Leave the maximum size at 4000Ko
• Do not tick the box: Truncate the existent log file
• Start up the vehicle (dashboard lights switched on) and try to connect to the vehicle.
• Shut the OBDuCAN software down.
• Send us your log file (named Trace.log by default) in an attached file at contact@synchroscan.com. Please specify your vehicle references, your interface references and the connection type (USB, bluetooth).
