AUDIO / VIDEO  AUDIO AND VISUAL SYSTEM(for Gasoline Model with Radio and Display Type (except 10.25 Inch Display))  Speaker Circuit  


DESCRIPTION

The sound signals amplified by the radio and display receiver assembly are sent to the speakers from the radio and display receiver assembly via the speaker circuit.

If there is a short in a speaker circuit, the radio and display receiver assembly detects it and stops output to the speakers.

Thus sound cannot be heard from the speakers even if there is no malfunction in the radio and display receiver assembly, telematics transceiver or speakers.

If a short is detected in a speaker circuit, no sound can be heard from the speakers.
