Air Switching Valve Operation Test
Refer to the Air Suction System Damage Inspection in the Periodic Maintenance chapter.
Air Switching Valve Unit Test
Special Tool - Hand Tester: 57001-1394
Air Switching Valve Resistance
Standard: 20
24 Ω at 20°C (68°F)

If the resistance reading is out of the specified value, replace it with a new one.


If the air switching valve dose not operate as described, replace it with a new one.

NOTE
To check air flow through the air switching valve, just blow through the air switching valve hose (intake side) [C].
