Normal Operation
The radio antenna receives AM and FM radio waves. The antenna module is integral with the roof-mounted antenna and receives voltage from the audio unit through circuit CME44 (YE/GN).

The noise suppression equipment reduces engine ignition and electrical systems interference transmitted through the speakers.

DTC B2103 - sets during the on-demand self-test when the signal strength is less than the configured minimum value. The audio unit must be tuned to AM during the self-test for this DTC to set. Also, the DTC will not set when the audio unit self-diagnostic mode is run.

Possible Causes
- Circuitry
- Antenna
- Antenna cable
- Charging system
