NAVIGATION SYSTEM Speaker Circuit

DESCRIPTION

If there is a short in a speaker circuit, the stereo component amplifier assembly detects it and stops output to the speakers.

Thus sound cannot be heard from the speakers even if there is no malfunction in the stereo component amplifier assembly or speakers.

  28. CHECK HARNESS AND CONNECTOR (STEREO COMPONENT AMPLIFIER ASSEMBLY - REAR NO. 3 SPEAKER ASSEMBLY)


    1. Disconnect the T32 stereo component amplifier assembly connector.

    2. Disconnect the T21 rear No. 3 speaker assembly connector.

    3. Measure the resistance between the stereo component amplifier assembly and the rear No. 3 speaker assembly to check for an open in the wire harness.

      Standard Resistance
      Tester Connection Condition Specified Condition
      T32-6 (WF1+) - T21-1 Always Below 1 Ω
      T32-21 (WF1-) - T21-2 Always Below 1 Ω

    4. Measure the resistance between the stereo component amplifier assembly or the rear No. 3 speaker assembly and body ground to check for a short in the wire harness.

      Standard Resistance
      Tester Connection Condition Specified Condition
      T32-6 (WF1+) or T21-1 - Body ground Always 10 kΩ or higher
      T32-21 (WF1-) or T21-2 - Body ground Always 10 kΩ or higher
