Good morning,

Why are you connecting it to your OBD connector? Did you check pin 16 for voltage? Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

check the Data link connector for any defects or loose wires. This is the plug that the scanner plugs into under the dash. You are getting the error code because you do not have a proper connection. I highly doubt that both yours and your neighbors link cable for the scanner is bad. Did you used ths same cable with both scanners? If so try a different cable and see if you still get the error code Good luck
