1. INSPECT AIR PUMP ASSEMBLY

1. Measure the resistance of the air pump.

   Standard resistance:

     Tester Connection | Specified Condition
     1 - 2 | 0.44 to 1.0 Ω at 20°C (68°F)
     1 - Body ground 2 - Body ground | 10 MΩ or higher

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

1. Check operation of the air pump.

   1. Check that air does not flow from port A to port B.
      If the result is not as specified, replace the air pump assembly.

   2. Apply battery voltage across terminals 1 and 2.

      NOTICE:
      1. Do not operate the air pump continuously for 5 seconds or more.
      1. When operating the air pump, wait until the pump has cooled down between each operation. If the pump has not cooled down sufficiently, the motor will burn out.

   3. Check that air flows from port A to port B.
      If the result is not as specified, replace the air pump assembly.
