Possible causes
- Signal wire between the module and the centre speaker shorted to supply voltage

- 1Check that the audio system fuses are intact and see where they are located in the owner's manual
- 2Check the connectors at the module and at the centre speaker for contact resistance, play and oxidation
- 3Look for chafing and damage where the wire could have touched a live circuit
- 4Read the signal with diagnostic equipment and repair the short to supply voltage
Symptoms you may notice1
