Checking the high-pressure fuel
pump
1.
Check the operation of the high-pressure
fuel pump using the YDIS “Stationary
test” and check the operating sound.
2.
Disconnect the high-pressure fuel pump
coupler “a”.
3.
Connect the tester probes to the termi-
nals of the high-pressure fuel pump cou-
pler, and then measure the input voltage
within 3 seconds after turning the engine
start switch to ON.
4.
Turn the engine start switch to OFF.
5.
Measure the high-pressure fuel pump
motor resistance.
6.
Connect the high-pressure fuel pump
coupler.
Checking the vapor shut-off valve
1.
Disconnect the vapor shut-off valve cou-
pler “a”.
2.
Turn the engine start switch to ON, and
then measure the input voltage between
the vapor shut-off valve coupler terminal
and ground.
3.
Remove the vapor shut-off valve, and
then connect the special service tool “1”
to the vapor shut-off valve.
4.
Apply the specified negative pressure to
the vapor shut-off valve.
