5. SUCTION CONTROL VALVE OPERATION SYSTEM
HINT:
The ECM controls the suction control valve operation to regulate the fuel volume that is pumped by the sup-
ply pump to the common rail. Consequently, the fuel pressure in the common rail is controlled to the target
injection pressure.
(a) Suction control valve opening small:
(1) When the opening of the suction control valve is small, the fuel suction area is kept small, there-
fore the transferble fuel volume is decreased.
(2) The suction volume becomes small due to the small suction area, despite the plunger stroke is
full. Therefore, the difference of the volume between the geometry volume and the suction vol-
ume is in vacuum condition.
(3) Pumping will start at the time when the fuel pressure has become higher than the common rail
pressure.
(b) Suction control valve opening large:
(1) When the opening of the suction control valve is large, the fuel suction area is kept large, there-
fore the transferble fuel volume is increased.
(2) If the plunger strokes fully, the suction volume will increase because the suction area is large.
(3) Pumping will start at the time when the fuel pressure has become higher than the common rail
pressure.

INSPECTION PROCEDURE
HINT:

If different DTCs related to different systems that have terminal E2 as the ground terminal are output
simultaneously, terminal E2 may be open.

Read freeze frame data using \f \b\f\f
. Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, it is useful for d\
etermining whether the vehicle
was running or stopped, the engine was warmed up or not, etc. at the time o\
f the malfunction.

(a)Connect the hand±held tester to the DLC3.
(b)Turn the ignition switch ON and push the hand±held tester main switch \
ON.
(c)Select the item ºDIAGNOSIS / OBD/MOBD / DATA LIST / ALL / COOLANT TEMPº and read its value displayed on the hand±held tester.
