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.

• Connect the 12 V battery [A] to the air switching valve terminals as shown in the figure.

• Blow the air to the intake air duct [A], and make sure does not flow the blown air from the outlet air ducts [B].
