Mute Signal Circuit Between Radio Receiver and Stereo Component Amplifier

AUDIO / VISUAL: AUDIO AND VISUAL SYSTEM (w/o Multi-display): Mute Signal Circuit between Radio Receiver and Stereo Component Amplifier
- Mute Signal Circuit between Radio Receiver and Stereo Component Amplifier

DESCRIPTION

The circuit sends a signal to the stereo component amplifier to mute noise. Because of that, the noise produced by changing the sound source ceases.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK HARNESS AND CONNECTOR (RADIO RECEIVER - STEREO COMPONENT AMPLIFIER)

(a) Disconnect the L51 receiver connector.





(b) Disconnect the R34 amplifier connector.

(c) Measure the resistance according to the value(s) in the table below.

Standard resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

2. CHECK STEREO COMPONENT AMPLIFIER ASSEMBLY (OPERATION)

(a) Replace the stereo component amplifier with a normal one and check if it operates normally Removal.

OK:

The audio system operates normally.

NG -- REPLACE RADIO RECEIVER ASSEMBLY Removal

OK -- END (STEREO COMPONENT AMPLIFIER ASSEMBLY IS DEFECTIVE)
