VACUUM SWITCHING VALVE(for ACIS) INSPECTION

PROCEDURE

1. INSPECT VACUUM SWITCHING VALVE ASSEMBLY NO.1 (for ACIS)

   1. 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)	27 to 33 Ω
      1 - Valve body	Always	10 kΩ or higher
      2 - Valve body

      If the result is not as specified, replace the vacuum switching valve assembly (for ACIS).

   2. Check the vacuum switching valve assembly (for ACIS) operation.

      1. 

         *a	Filter
         *b	Port E
         *c	Air

         When vacuum is applied to port E, check that air is sucked into the filter.

         Standard

         Air is sucked into filter.

         If the result is not as specified, replace the vacuum switching valve assembly (for ACIS).

      2. 

         *a	Air
         *b	Port E
         *c	Port F

         Apply battery voltage across the terminals. When vacuum is applied to port F, check that air is sucked into port E.

         Standard

         Air is sucked into port E.

         If the result is not as specified, replace the vacuum switching valve assembly (for ACIS).
