9. Are you receiving an error stating that the OBD-II interface module could
not be detected?
Yes:
Make sure that you have selected the correct serial port under ProScan’s
Communication Settings dialog.
Make sure that the interface is receiving power as indicated by its LEDs.
Make sure that the cables and interface are securely fastened between the
vehicle and your PC.
If you are using a USB-to-Serial adapter, make sure that you have
installed the drivers according to the manufacturer’s instructions. Also
make sure that the serial port being emulated by the adapter is the one
selected under ProScan’s Communication Settings.
If you are using an ELM327-based interface, make sure that the correct
baud rate setting is selected under ProScan’s Communication Settings.
This is typically 9600 baud, but it could be 38400.
No:
Continue to the next step.
10. Are you receiving an error stating that the OBD-II interface module could
not be initialized?
Yes:
Make sure that your OBD-II interface module is selected under the
Hardware section of ProScan’s Communication Settings dialog.
No:
Continue to the next step.
11. Are you receiving an error stating that the OBD-II interface module was
detected and initialized, but communication with the vehicle could not be
established?
Yes:
Make sure that your OBD-II interface module is selected under the
Hardware section of ProScan’s Communication Settings dialog.
If you are using an ELM327-based interface, and the protocol is set to
“Automatic” under ProScan’s Communication Settings, then you may
need to specify the protocol to use. The automatic protocol detection
usually works, but it is not guaranteed.
If you are using an ELM327-based interface, you can also try bypassing
initialization. To do this, select “Bypass Initialization” under the
ELM327 configuration section of ProScan’s Communication Settings.
No:
Continue to the next step.
