NAVIGATION SYSTEM(for Navigation Receiver Type) Sound Signal Circuit between Navigation Receiver Assembly and Stereo Component Amplifier

DESCRIPTION

The navigation 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 the speakers even if there is no malfunction in the stereo component amplifier assembly or speakers.

PROCEDURE


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


    1. Disconnect the F1 navigation receiver assembly connector.

    2. Disconnect the F7 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
      F7-5 (R+) - F1-1 (FR+) Always Below 1 Ω
      F7-4 (R-) - F1-5 (FR-) Always Below 1 Ω
      F7-3 (L+) - F1-2 (FL+) Always Below 1 Ω
      F7-2 (L-) - F1-6 (FL-) Always Below 1 Ω
      F7-6 (SLD) - Body ground Always 10 kΩ or higher
      F7-5 (R+) or F1-1 (FR+) - Body ground Always 10 kΩ or higher
      F7-4 (R-) or F1-5 (FR-) - Body ground Always 10 kΩ or higher
      F7-3 (L+) or F1-2 (FL+) - Body ground Always 10 kΩ or higher
      F7-2 (L-) or F1-6 (FL-) - Body ground Always 10 kΩ or higher
