Melcodiag Monster 1100 EVo no connection

[TRS666]

Hello. I have been trying to connect Melcodiag and M3C9 to my Monster 1100 EVO to reset service wrench. Used 2 different laptops with Windows 10, Lonelec 4 pin cable and ELM 327 which should have correct chip, pic18f24k80. I know the right COM port number also and have tested with diffrent COM:s and different speeds. Tested probably some 20 times and always get this message "can´t init elm, check your settings com number and com speed".
Could it be problem that i have a PC V in the bike that disturbs the connection, or problem with something else like the cable. The red light on the ELM is lit when connected and the next green flashes slowly.

are you sure it's an elm interface and not a kkl one ?
do you know the comport used by the elm ?
