(Engine Control Unit), a "LINKING ERROR!" message
shows up on the display.
Verify that the ignition is ON;
Check if the scan tool's OBD II connector is securely
connected to the vehicle's DLC;
Verify that the vehicle is OBD2 compliant;
Turn the ignition off and wait for about 10 seconds. Turn the
ignition back to on and repeat the procedure from step 5.
If the "LINKING ERROR" message does not go away, then
there might be problems for the scan tool to communicate
with the vehicle. Contact your local distributor or the
manufacturer's customer service department for assistance.
