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
3) Error while switching ON and OFF on 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 the 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 diacnostic 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 switch ON and OFF properly 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 the correct serial protocol to use or contact the Race Technical support.
