Always perform the Radio/Audio System Diagnostic System Check before proceeding with these diagnostic procedures. Refer to Diagnostic System Check - Radio/Audio System. Diagnostic System Check

ALL SPEAKERS INOPERATIVE

IMPORTANT: The following information lists the most probable cause of the concern to the least probable cause followed by the appropriate test for that condition.

If the list leads to the replacement of a component, always inspect for a poor connection before proceeding with the replacement.

Without RPO UZ8
- Speaker output shorted - Test all speaker outputs for a short.
- Defective radio - Replace the radio.

With RPO UZ8 (Monsoon)
1. Battery positive voltage circuit to the amplifier open. Test the battery positive voltage circuit to the amplifier for an open.
2. Low level audio signal circuit shorted. Test all low level audio signal circuits for a short to ground or short to voltage.
3. 14-volt reference circuit open or shorted to ground. Test the 14-volt reference circuit for an open or short to ground.
4. No low level audio output from the radio. Test for any AC voltage between the left front low level audio signal circuits at the amplifier harness connector, disconnected with the radio volume adjusted to 50 percent. If no AC voltage is present, replace the radio.
5. No audio output from the amplifier. Replace the amplifier.

IMPORTANT: The following procedure assumes that all speakers are operative for all modes of operation except digital radio.

With RPO U2K
1. Left or right audio signal (+) circuit shorted. Test both audio signal (+) circuits for a short.
2. No audio output from the digital radio receiver. Replace the digital radio receiver.
3. No digital radio output from the radio. Replace the radio.
