No service light here
I have not seen the service message since putting in the junkyard fdcm.
The service message comes when the fdcm posts a fault code. I would try just clearing the fault code one more time and see if that gets rid of the service message. It should not come back after that because you now have a properly functioning fdcm that will not be posting anymore fault codes.
