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

DESCRIPTION

The multi-media module receiver assembly sends the sound signal to the stereo component amplifier assembly through 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, multi-media module receiver assembly, DCM (telematics transceiver)* or speakers.

PROCEDURE

1. CHECK HARNESS AND CONNECTOR (MULTI-MEDIA MODULE RECEIVER ASSEMBLY - STEREO COMPONENT AMPLIFIER ASSEMBLY)

   
   

   1. Disconnect the F102 multi-media module receiver assembly connector.

   2. Disconnect the F103 stereo component amplifier assembly connector.

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

      Standard Resistance

      Tester Connection Condition Specified Condition F102-2 (MI+) - F103-5 (MO+) Always Below 1 Ω F102-3 (MI-) - F103-6 (MO-) Always Below 1 Ω F102-4 (SLDI) - F103-7 (SLDO) Always Below 1 Ω F102-5 (MO+) - F103-2 (MI+) Always Below 1 Ω F102-6 (MO-) - F103-3 (MI-) Always Below 1 Ω F102-7 (SLDO) - F103-4 (SLDI) Always Below 1 Ω F102-1 (WUO) - F103-8 (WUI) Always Below 1 Ω F102-2 (MI+) or F103-5 (MO+) - Body ground Always 10 kΩ or higher F102-3 (MI-) or F103-6 (MO-) - Body ground Always 10 kΩ or higher F102-4 (SLDI) or F103-7 (SLDO) - Body ground Always 10 kΩ or higher F102-5 (MO+) or F103-2 (MI+) - Body ground Always 10 kΩ or higher F102-6 (MO-) or F103-3 (MI-) - Body ground Always 10 kΩ or higher F102-7 (SLDO) or F103-4 (SLDI) - Body ground Always 10 kΩ or higher F102-1 (WUO) or F103-8 (WUI) - Body ground Always 10 kΩ or higher
