Replacing DME Control Modules Unnecessarily
Vehicle Type:

Concern:
Replacing functional DME control modules unnecessarily due to fault codes in the DME fault memory, whose cause is not the DME control module.

malfunction, however faults codes related to other components (e.g., secondary-air pumps).
