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].

Turn Signal Relay InspectionTire Wear, Damage
As the tire tread wears down, the tire
becomes more susceptible to puncture
and failure. An accepted estimate is
that 90% of all tire failures occur during
the last 10% of tread life (90% worn).
So it is false economy and unsafe to
use the tires until they are bald
In accordance with the ...
Turn Signal Relay Inspection
Remove the battery (see Battery Removal).
Take the turn signal relay [A] off the rear fender.
Disconnect the connector [B].
Connect one 12 V battery and turn signal lights as indicated
in the figure, and count how many times the lights
blink for one minute.
Turn Signal Relay ...
Intake Air Pressure Sensor #1 Installation
NOTE
The intake air pressure sensor #1 is the same part as
the intake air pressure sensor #2.
Installation is basically the reverse of removal.
Position the intake air pressure sensor #1 [A] between the
projections [B] on the rubber damper.
Install the rubber damper [A] on the bracket ...
