Dear members,
I have a ford focus ST LINE eco blue 2018, I have changed my alternator to a 350A for car audio, with an external regulator
So far we had to disconnect LIN I need to know how to disable it from ECU for delete error in forscan error code U012D I tried entering in PCM module, disable primary alternator, also disabled BMS and all things related with battery but no way to delete this error
Not sure if changing AS-BUILT
I dont know what more to do to disable LIN and stop geting this error with battery warning check
Any ideas? I have forscan myself and I can do whatever you ask
