Always inspect the trouble taking the following items into consideration.
^ Open or short circuit of the wire harness
^ Connector or terminal connection fault
^ The cassette tape or compact disc itself may be causing the trouble, so when troubleshooting the tape player or CD player, always use a different cassette tape or compact disc first of all to check operation of the tape player or CD player.
