    1. A00Y8Y8C01
      *a

      Component without harness connected

      (Back Sonar or Clearance Sonar Switch Assembly)

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      9 (IG) - 6 (ECU) Back sonar or clearance sonar switch assembly on Below 1 Ω
      9 (IG) - 6 (ECU) Back sonar or clearance sonar switch assembly off 10 kΩ or higher

      If the result is not as specified, replace the back sonar or clearance sonar switch assembly.

    2. Check that the switch illuminates.


      1. A00Y8Y8C02
        *a

        Component without harness connected

        (Back Sonar or Clearance Sonar Switch Assembly)

        Apply battery voltage to the back sonar or clearance sonar switch assembly and check that the switch illuminates.

        OK
        Tester Connection Specified Condition

        Battery positive (+) → Terminal 8 (ILL+)

        Battery negative (-) → Terminal 7 (ILL-)

        Illuminates

        If the result is not as specified, replace the back sonar or clearance sonar switch assembly.

    3. Check switch indicator operation.
