Normal Operation
The radio antenna, integral to the rear window, receives AM and FM radio waves. The antenna module, which receives voltage from the audio unit through circuit CME35 (VT/BK), 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.

NOTE: When installing any new noise suppression equipment components, make sure that a good contact is made at all connections. Remove any paint or dirt from between a component and its ground. Tighten all connectors and fasteners securely.

Possible Causes
- Circuit CME35 (VT/BK) open or short to ground
- Antenna
- Antenna cable
- Antenna module
- Noise suppression equipment
- Audio unit
