Tell us on which controlers you can connect by Launch and you cannot connect by OP-COM.
When you do an automatic scan by OP-COM you will see a lot of controlers there that there is no communication. One of item you don't have item in your car and others maybe you cannot see item because that one are on CH-CAN. And if you have a REV B interfa e you will never be able to connect to this controlers and if you have a moded Rev C you can connect to item but you will haven't seen item in the list as connected.
Only if you have a Rev D you can see item connected in automatic scan list.
Good luck
