[Error 3000] communication error between the instrument (New Genius MyGenius) and ECU

NewGenius/MyGenius displays "Error 0X3000" while communicating with the ECU of a vehicle.

 Cause

1) The cable used for the connection is not the correct one.

2) The connection on the vehicle socket is not correct or the cable used is damaged. Also, make sure that the diagnostic port is the correct one.

3) Error while switching ON and OFF the dashboard during the communication procedures. 

4) Wrong selection of the vehicle or of the serial protocol.

5) The ECU present on the vehicle is not the supposed one or what we expect to find.

Solution

 1) Verify that the cable used for communication is the correct one. Open the manual corresponding to the serial protocol and check it.

2) Make sure that the cable is well connected to the correct diagnostic port, on some vehicles, there could be different diagnostic ports. Open the manual corresponding to the serial protocol and check it. 
To verify the integrity and proper functioning of the cable try to use it on another similar vehicle and verify if there is the same fault.

  
3) When requested by the tool to switch ON and OFF the dashboard, you must always wait 10 seconds before proceeding with the next operation.

4) Ensure that you selected the correct vehicle or the correct protocol for your vehicle.

5) If the ECU does not correspond to what you expect you must search for the correct serial protocol to use.
