Issue Details

I am using the OBD Engine Monitor example that comes with the Automotive Diagnostic Command Set (ADCS) Toolkit. I receive Error -8260 when I run my example. How can I get rid of this error?


Error -8260 signifies a timeout with the driver. It is possible to clear the error in LabVIEW to ignore it, but it would be worth checking the following to make sure you aren't losing data:
  • Double check the CAN messages that are causing the timeout to ensure they are properly formatted.
  • Verify that another device can read the data you are trying to send.
  • Check baud rates, termination, and cabling (e.g.: make sure DB9 to OBD cable has correct wiring pin-outs)
