Normal Operation
For MKZ, and early build Fusion and Milan, the radio antenna, integral to the rear window, receives AM and FM radio waves. The antenna module sends the radio waves to the audio unit through the antenna cable.

For late build Fusion and Milan, the antenna receives AM and FM radio waves and transmits them to the audio unit through the antenna cable.

For all vehicles, the noise suppression equipment reduces engine ignition and electrical systems interference transmitted through the speakers.

DTC B2103 - sets when an open is detected in the antenna circuit.

Possible Causes
- Circuit CME35 (VT/BK) open or short to ground (early build Fusion, Milan only)
- Circuit CME44 (YE/GN) open or short to ground (MKZ only)
- Antenna
- Antenna cable
- Antenna module (MKZ only)
