The only thing I can assume is the problem is is that the COM ports have become mixed up. I believe the scanner needs to use COM3 and it could be that this may be being used by another device. We had this problem a while back and no matter how many times we re-added the device it would take a COM port higher than 4 or 5 and not any lower. If you can reset all the COM ports and re-add the scanner device then that should work.

well i borrowed my friends obdII scanner and im trying to check my codes but everytime is says link error? im stumped i tried it multiple times with. ... but it sounds like you may have an electrical problem somewhere. Discovery ...
<p>Bar code symbols are composed of a number of adjacent bars
and spaces of different widths of pre-defined codes. A barcode scanner is used
to read or scan the bar code symbol to represent the information to decode.
Once the symbol is scanned by a handheld reading device or another, can then be
used by computer software to track inventory and perform other functions.
Microsoft Excel is a computer application that use bar code information can
make the business perform. <br />
<p>1. Insert bar code scanner to your computer using the
"interface cable keyboard wedge". The keyboard wedge interface cable
looks like the printer port of your computer, and differs only in that a
connection between the scanner bar code and serial number of your computer or
USB port. The cable is provided as a peripheral pattern with hand-held bar code
scanners. <br />
<p>2. Open Microsoft Excel on your computer after the bar code
scanner connected to your computer. <br />
<p>3. Links on the Excel cell to the bar code to enter and bar
code scanning to load it into Microsoft Excel. <br />
<p>4. View the data in Excel file is translated into a vision
of the bar code information. <br />
This code pertains to communication from one computer to the next,they all are on a communication circuit (class II) & you have a short to ground somewhere.If a scan tool is able to communicate with the computer(and it is since you got a failure code) this code is intermitten.Get a good volt meter or scan tool & start at the ALDL (where the scanner plugs in).Inspect & check wiring as you keep an eye on the scanner or meter.
DTC Parameters DTC U1300 will set if the EBTCM, PCM, or SDM detected the Class II circuit in the low state for too long. (Class II circuit shorted to ground) when: • Condition exists for longer than 4 seconds for EBTCM, 2 seconds for PCM and SDM. • Ignition is On.
DTC U1300 diagnostic runs continuously with ignition On.
DTC U1300 is a type C DTC. Diagnostic Aids If the scan tool can communicate with the EBTCM, PCM or SDM, then the Class II link is not currently shorted to ground.
Inspect the wiring harness for signs of chafing or broken insulation.
Important: The controller name won't be displayed until the scan tool initially received the correct controller ID over the link upon ignition On.
Important: The BCM CANNOT set U1300.
To locate an intermittent problem, use the scan tool to monitor any of the controllers on the Class II link located under DIAGNOSTIC CIRCUIT CHECK - - - CLASS II MESSAGE MONITOR with ignition On, engine Off. INACTIVE will be displayed on all controllers if the link is shorted to ground.
No scanner communication can be caused by many different issues. #1 be sure you have power and ground at the diagnostic connector. Many times this power supply in on the "cigar" fuse or "accesory" fuse. Drop a dime in the cigar lighter...blow the fuse and no communication occurs.
First try to scan from the scanners and camera wizard in control panel to check the communication between the computer and the all-in-one. If we are able to scan fine from the control panel, then search for the scanning file hpqscnvw.exe and try to scan from there, if you are able or not able to scan from the scanning file, download the scan diagnostic utility from the HP website and run it and try to scan, if the issue persists reinstall the all-in-one software.
