INSPECTION
INSPECT IDLE AIR CONTROL VALVE OPERATION
(a) Apply battery voltage to terminals B1 and B2, and while repeatedly grounding S1 −S2−S3−S4−S1 in sequence,
and check that the valve moves toward the closed posi-
tion.

09641 −01060)
NOTICE:
Check that the valve of the SST is in the open position.
(c) Bleed the power steering system (See page SR−3).
(d) Start the engine and run it at idle.
(e) Turn the steering wheel from lock to lock several times to
boost fluid temperature.
Fluid temperature: 80° C (176°F)
(f) With the engine idling, close the valve of the SST and ob-
serve the reading on the SST.
Minimum fluid pressure:
9,316kPa (95 kgf/cm
