CLEARANCE SONAR MAIN SWITCH INSPECTION

PROCEDURE

  1. INSPECT TELLTALE LIGHT ASSEMBLY (CLEARANCE SONAR MAIN SWITCH)

    1. E269059C05

      *a

      Component without harness connected

      (Telltale Light Assembly (Clearance Sonar Main Switch))

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

      Standard Resistance

      Tester Connection

      Switch Condition

      Specified Condition

      1 (ECU) - 9 (LAPB)

      Clearance sonar main switch off

      10 kΩ or higher

      Clearance sonar main switch on

      Below 1 Ω

      If the result is not as specified, replace the telltale light assembly (clearance sonar main switch).

    2. E269059C06

      *a

      Component without harness connected

      (Telltale Light Assembly (Clearance Sonar Main Switch))

      Check that the switch illuminates.

      1. Apply battery voltage to the telltale lightassembly (clearance sonar main switch) and check that the switch illuminates.

        OK
