Toyota Camry (XV70): Sound Signal Circuit between Radio Receiver and Stereo Component Amplifier

Toyota Camry Repair Manual XV70 (2018-2024) / Audio, Visual, Telematics / Audio / Video / Audio And Visual System / Sound Signal Circuit between Radio Receiver and Stereo Component Amplifier

DESCRIPTION

The radio and display receiver assembly sends a sound signal to the stereo component amplifier assembly via this circuit.

The sound signal that is sent is amplified by the stereo component amplifier assembly, and then is sent to the speakers.

If there is an open or short in this circuit, sound cannot be heard from the speakers even if the stereo component amplifier assembly or speakers are not malfunctioning.
