Toyota Sienna Service Manual / Audio / visual / Audio and visual system / Diagnostic trouble code chart / Sound Signal Circuit between Radio Receiver and Television Display Assembly

DESCRIPTION

The television display assembly sends a sound signal to the radio receiver through this circuit.

The sound signal that has been sent is amplified by the stereo component amplifier or radio receiver (built-in amplifier), and then is sent to the speakers.

If there is an open or short in the circuit, sound cannot be heard from the speakers even if there is no malfunction in the stereo component amplifier, radio receiver, or speakers.
