КЛАПАН ПЕРЕКЛЮЧЕНИЯ ПОДАЧИ ВОЗДУХА (для моделей с вспомогательной системой подачи воздуха в нейтрализатор) ПРОВЕРКА

PROCEDURE

1. INSPECT AIR SWITCHING VALVE ASSEMBLY

   
   

   1. 

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

      Standard Resistance
      Tester Connection Condition Specified Condition 1 - 5 20°C (68°F) 4.5 to 5.5 Ω 1 - Body ground Always 1 MΩ or higher 5 - Body ground

      Note

      When measuring the resistance, do not touch terminals 2, 3 and 4.

      If the result is not as specified, replace the air switching valve assembly.

   2.

      Air

      Check the operation of the air switching valve.

      
      

      1. Check that air does not flow from port A to port B.

         Note

         Make sure the applied pressure is 30 kPa (0.3 kgf/cm², 4.4 psi) or less

         If the result is not as specified, replace the air switching valve assembly.

      2.

         Air

         Apply battery voltage to the connector, and check the air switching valve operation.

         OK
         Measurement Condition Specified Condition Battery positive (+) → Terminal 1 Battery negative (-) → Terminal 5 Air flows from port A to port B

         Note

         When applying voltage, do not touch terminals 2, 3 and 4.

         If the result is not as specified, replace the air switching valve assembly.
