1st. in VisualME7Logger: try to connect to car with Ignition OFF
wait a few..
Are you getting values? but 0000000's?
Good!
Now: Turn the Key to the ON (Ign. ON) position. wait a.. ..
Does it Freeze up with error Code 4? Better..!
now try to start logging the car when you removed the instrument cluster, if immobilizer is a deal...first start the car, remove cluster connector (where K-line is located) and now press start logging in visualme7logger.
Does it Log now? Yes..? Great.. somehow the cluster is interrupting the K-line when trying to log. run a straight K-line from ecu pin to obd-device or fab some switch.
worked for me
