Normal Operation
The radio antenna, integral to the right quarter glass, receives AM and FM radio waves. The antenna module, which receives voltage from the audio unit through circuit CME13 (YE/OG), sends the radio waves to the audio unit through the antenna cable.

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

Possible Causes
- Circuit CME13 (YE/OG) open or short to ground
