  1. Disconnect the connectors shown in the illustration from the radio receiver and speakers.

  1. Measure the resistance between each of the front No. 2 speakers and the radio receiver to check for an open circuit in the wire harness.

    Standard resistance:
    Below 1 Ω

  1. Measure the resistance between each of the front No. 2 speakers and each of the front No. 1 speakers to check for an open circuit in the wire harness.

    Standard resistance:
    Below 1 Ω

  1. Measure the resistance between each of the rear speakers and the radio receiver to check for an open circuit in the wire harness.

    Standard resistance:
    Below 1 Ω

  1. Measure the resistance between each speaker and body ground to check for a short circuit in the wire harness.

    Standard resistance:
    10 kΩ or higher


NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
OK


2.INSPECT FRONT NO. 1 SPEAKER

  1. Resistance check.

    1. Measure the resistance between the terminals of the speaker.

      Standard resistance:
      Approximately 4 Ω


NG
REPLACE FRONT NO. 1 SPEAKER
OK


3.INSPECT FRONT NO. 2 SPEAKER

  1. Check that the malfunction disappears when another speaker in good condition is installed.

    Standard:
    Malfunction disappears.
    HINT:
    1. Connect all the connectors to the front No. 2 speaker.
    2. When there is a possibility that either the right or left front speaker is defective, inspect by interchanging the right one with the left one.
    3. Perform the above inspection on both LH and RH sides.


OK
REPLACE FRONT NO. 2 SPEAKER
NG


4.INSPECT REAR SPEAKER

  1. Resistance check.

    1. Measure the resistance between the terminals of the speaker.

      Standard resistance:
      Approximately 4 Ω


NG
REPLACE REAR SPEAKER
OK
