IDLE UP SYSTEM CHECK
1) Warm up engine to normal operating temperature.
2) Turn A/C switch OFF, if equipped.
3) Turn steering wheel fully and check idle speed.
Engine idle speed drops a little momentarily when steering
wheel is turned fully but returns to its specified level immediately.
If power steering pressure switch connector is connected, check
the same with that connector disconnected. Momentary drop of
engine idle speed should be less when it is connected than when
disconnected.

visually check gear box, P/S pump and P/S fluid reservoir themselves and each joint of their connecting pipes for
leakage.
CAUTION:
Never keep steering wheel turned fully for longer than 10 seconds.
