AUDIO AND VISUAL SYSTEM(for Radio Receiver Type) Speaker Circuit

DTC Code DTC Name
Speaker Circuit

DESCRIPTION

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.
