What to do if scanner communication cannot be established?
Scanner communication cannot be established. Ensure your product is powered on, check the connection, and ensure your network is functioning properly. If these conditions are correct, restart the product and try scanning again. If you are running firewall software, it may be blocking scan communication.
Why is my Sparky scan tool not communicating?
When this condition is encountered you generally end up at a screen that states that the module will not communicate. Not a big deal if you know your tool and realize you need to check those circuits. Unfortunately many times a technician is thrown off by this and starts looking for problems with the data communication lines.
Where to find fault code for no communication?
It could also be the HVAC module or Instrument dash panel modules shown on the bottom left of the diagram (splice 221).The scanner will point you to the right module most of the time. 2.) If the fault code is the SDM module failure combine with NO START, you need to do some initial basic tests.
Why does my scan tool not power up?

Why is there no Comm on my scan tool?
Could the magnetic interference of all the wires being bundled together cause the lack of communication to the scan tool?? I know that there are 2 pins on the DLC that can be tested for resistance to see how far the lack of comm goes. can anyone tell me what pins and how much resistance there should be?
What does no start no crank no click mean?
If you have a late model GM vehicle and turn the key only to hear nothing, you’ll most likely think you have a dead battery—and you may. But a no start, no crank, no click condition can be far more involved than that. In the old days, power flowed through the ignition switch and down to the starter solenoid. Not anymore.
