  1. INSPECT AIR PUMP ASSEMBLY


    1. A01EQJ8E04

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 - 2 20°C (68°F) 0.4 to 1.0 Ω
      1 - Body ground Always 10 kΩ or higher
      2 - Body ground

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

    2. A01ENNLE01

      Check the operation of the air pump.


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

      2. A01EP11E04

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

        OK
        Measurement Condition Specified Condition

        Battery positive (+) → Terminal 2

        Battery negative (-) → Terminal 1

        		 Air flows from port A to port B

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

        Note


        • Do not operate the air pump continuously for 2 minutes or more.

        • When operating the air pump, wait 5 minutes until the pump has cooled down between each operation. If the pump has not cooled down sufficiently, the motor will burn out.
