(g) With the engine idling, close the valve of the SST and ob-
serve the reading on the SST.
Minimum fluid pressure:
10,000 kPa (102 kgf/cm
2, 1,451 psi)
NOTICE:
Do not keep the valve closed for more than 10 se-
conds.
Do not let the fluid temperature become too high.
(h) With the engine idling, open the valve fully.
(i) Measure the fluid pressure at engine speeds of 1,000 rpm
and 3,000 rpm.
Difference fluid pressure:
490 kPa (5 kgf/cm
2, 71 psi) or less
NOTICE:
Do not turn the steering wheel.
(j) With the engine idling and valve fully opened, turn the
steering wheel to full lock.
Minimum fluid pressure:
10,000 kPa (102 kgf/cm
2, 1,451 psi)
NOTICE:
Do not maintain lock position for more than 10 se-
conds.
Do not let the fluid temperature become too high.
(k) Disconnect the SST.
