Radio/Stereo

Voltage is available at all times to the Radio from RADIO-B Fuse 19 through the ORN (1440) wire. This voltage provides power to the radio memory storage for time and station presets. It also provides power to the Theftlock circuit, if provided. Operating power is available to the Radio when the Ignition Switch is in RUN or ACCY from RADIO-I Fuse 17 through the YEL (43) wire. The Radio is grounded by the BLK (150) wire at Ground G201. Refer to Audio Systems for a description of Radio controls and functions.

The optional Power Antenna is controlled by the PNK (314) wire. Voltage on this wire raises the Power Antenna automatically. when the Radio is turned off, the voltage is removed, and the antenna lowers. Refer to Power Antenna for additional information. Antenna

The optional Speed Compensating Volume signal from the Vehicle Control Module (Gasoline Engines) or from the Vehicle Speed Sensor Buffer (Diesel Engines) is provided by the DK GRN (817) wire. This signal is switched to ground at a frequency of 4000 pulses per mile. Using adjustments on the Radio, the volume of the radio may be increased in proportion to vehicle speed to compensate for road and wind noise. When the vehicle stops, the Radio volume returns to the previously adjusted volume.
