DESCRIPTION
If there is a short in a speaker circuit, the stereo component amplifier assembly detects it and stops output to the speakers.
As a result, sound cannot be heard from the speakers even if there is no malfunction in the stereo component amplifier assembly, DCM (telematics transceiver)* or speakers.
