engine. Discard the fluid,
Refit the return hose on the reservor.
Fill the reservoir to the uDoer level line.
Start the engine and run it at fast idle, then turn the

Start the engine and let it idle.
Turn the stee.ing wheel from lock-to-lock several
times to warm the fluid to operating temperature.
Measure steady-state fluid pressure while idling
with the shut-off valve fully open. lf the pump is in
good condition, the gauge should read less than
1500 kpa (15 kgf/cm,,213 psi).
lf it reads high, check the feed line or valve body
unit (see General Troubleshooting l7-10).
Close the shut-off valve. then close the pressure
control valve gradually until the pressure gauge
needle is stabl6, Read the pressure.
lmmediately open the shut-off valve fully.
CAUTION: Do not keep the shut-ott valvs closod
moro thgn 5 soconds or th9 pump could b6 dam"

lf the pump is in good condition, the gauge should
read at least 6.400 - 7,400 kpa (65 - 75 kgIlcm,,924- 1,067 psi). A low reading means pump output is
too low for full assist. Repair or replace the pump.
