Lexus ES: Sound Signal Circuit between Radio Receiver and Stereo Component Amplifier

Lexus ES (XZ10) Service Manual / Audio & Visual & Telematics / Audio / Video / Audio And Visual System (for Gasoline Model) / Sound Signal Circuit between Radio Receiver and Stereo Component Amplifier

DESCRIPTION

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

The sound signal that has been sent is amplified by the stereo component amplifier assembly, 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 assembly or speakers.
