AUDIO AND VISUAL SYSTEM > Sound Signal Circuit between Radio Receiver and Stereo Component Amplifier

for Preparation Click here


DESCRIPTION

The radio receiver assembly sends a sound signal to the stereo component amplifier through this circuit. The sound signal that is sent is amplified by the stereo component amplifier, and then is sent to the speaker. If there is an open or short in the circuit, sound cannot be heard from the speaker even if there is no malfunction in the stereo component amplifier or speaker.

INSPECTION PROCEDURE

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


    E109064E02

  1. Disconnect the L54 radio receiver assembly and V29 stereo component amplifier connectors.

  1. Measure the resistance of the wire harness side connectors.

    Standard resistance:
    Tester Connection
    		Specified Condition
    V29-3 (L+) - L54-9 (L+)
    		Below 1 Ω
    V29-2 (L-) - L54-19 (L-)
    		Below 1 Ω
    V29-5 (R+) - L54-8 (R+)
    		Below 1 Ω
    V29-4 (R-) - L54-18 (R-)
    		Below 1 Ω
    V29-3 (L+) - Body ground
    		10 kΩ or higher
    V29-2 (L-) - Body ground
    		10 kΩ or higher
    V29-5 (R+) - Body ground
    		10 kΩ or higher
    V29-4 (R-) - Body ground
    		10 kΩ or higher
    L54-9 (L+) - Body ground
    		10 kΩ or higher
    L54-19 (L-) - Body ground
    		10 kΩ or higher
    L54-8 (R+) - Body ground
    		10 kΩ or higher
    L54-18 (R-) - Body ground
    		10 kΩ or higher
