For 1990-2009 cars only
Radio
The radio receives battery voltage at all times on circuit 640 through the RADIO BATT fuse. This keeps the clock and preset memory alive when the ignition is in the OFF position. The radio is grounded through circuit 351. When the ignition is in the ACCY or RUN position, the following conditions are true:
| • | Voltage is applied to circuit 43 through the RADIO fuse in order to enable the radio operation |
| • | The vacuum florescent (VF) display illuminates to display the time or radio frequency setting with the ignition switch ON. |
Compact Disc (CD) and Cassette Player
The CD or cassette player, if equipped, is part of the radio unit. The same power required by the radio is necessary for the tape or CD operation.
Remote CD Changer
The remote CD changer receives battery positive voltage at all times through the CD CHG fused circuit 2640. The remote CD changer is grounded through circuit 351.
Low Frequency Audio Amplifier
The amplifier receives battery voltage at all times through circuit 640. The amplifier is grounded through circuit 351.
