AUDIO AND VISUAL SYSTEM (for Radio and Display Type) - 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 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 speakers even if there is no malfunction in the stereo component amplifier assembly or speakers.
WIRING DIAGRAM
INSPECTION PROCEDURE
| 1.CHECK HARNESS AND CONNECTOR (RADIO AND DISPLAY RECEIVER ASSEMBLY - STEREO COMPONENT AMPLIFIER ASSEMBLY) |
Disconnect the F18 stereo component amplifier assembly connector.
Disconnect the F120 radio and display receiver assembly connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition F120-1 (FR+) - F18-5 (R+) Always Below 1 Ω F120-2 (FL+) - F18-3 (L+) Always Below 1 Ω F120-5 (FR-) - F18-4 (R-) Always Below 1 Ω F120-6 (FL-) - F18-2 (L-) Always Below 1 Ω F18-6 (SLD) - Body ground Always 10 kΩ or higher F120-1 (FR+) - Body ground Always 10 kΩ or higher F120-2 (FL+) - Body ground Always 10 kΩ or higher F120-5 (FR-) - Body ground Always 10 kΩ or higher F120-6 (FL-) - Body ground Always 10 kΩ or higher
