AUDIO AND VISUAL SYSTEM(except 8 Speakers) 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 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, radio receiver assembly, DCM (telematics transceiver)* or speakers.

• *: w/ Telematics Transceiver

WIRING DIAGRAM

PROCEDURE

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

   
   

   1. Disconnect the I102 radio receiver assembly connector.

   2. Disconnect the P29 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 I102-1 (WUO) - P29-8 (WUI) Always Below 1 Ω I102-2 (MI+) - P29-5 (MO+) Always Below 1 Ω I102-3 (MI-) - P29-6 (MO-) Always Below 1 Ω I102-4 (SLDI) - P29-7 (SLDO) Always Below 1 Ω I102-5 (MO+) - P29-2 (MI+) Always Below 1 Ω I102-6 (MO-) - P29-3 (MI-) Always Below 1 Ω I102-7 (SLDO) - P29-4 (SLDI) Always Below 1 Ω I102-1 (WUO) or P29-8 (WUI) - Body ground Always 10 kΩ or higher I102-2 (MI+) or P29-5 (MO+) - Body ground Always 10 kΩ or higher I102-3 (MI-) or P29-6 (MO-) - Body ground Always 10 kΩ or higher I102-4 (SLDI) or P29-7 (SLDO) - Body ground Always 10 kΩ or higher I102-5 (MO+) or P29-2 (MI+) - Body ground Always 10 kΩ or higher I102-6 (MO-) or P29-3 (MI-) - Body ground Always 10 kΩ or higher I102-7 (SLDO) or P29-4 (SLDI) - Body ground Always 10 kΩ or higher
