(b) COMMON RAIL SYSTEM COMPONENTS:
ComponentDescription
Common railStores high −pressurized fuel produced by the supply pump
Supply pumpOperated by the crankshaft, and supplies high −pressure fuel to the common rail
InjectorInjects fuel to the combustion chamber based on signals from the ECM
Fuel pressure sensorMonitors internal fuel pressure of the common rail and sends signals to the ECM
Pressure discharge valveBased on signals from the ECM, opens the valve when sudden deceleration is occurred, or when the ignition switch is
OFF to prevent the fuel pressure from becoming too high
Suction control valveBased on signals from the ECM, adjusts fuel volume supplied to the common rail and regulates the internal fuel pres-
sure

MECHANICAL SYSTEM TESTS
1. PERFORM MECHANICAL SYSTEM TESTS
(a) Measure the stall speed.
The object of this test is to check the overall performance of the transaxle and engine by measuring
the stall speeds in the D and R positions.
NOTICE:
SPerform the test at the normal operating ATF (Automatic Transmission Fluid) temperature 50
to 80˚C(122 to176˚F).
SDo not continuously run this test for longer than10 seconds.
STo ensure safety, do this test in a wide, clear level area which provides good traction.
SThe stall test should always be carried out in pairs. One technician should observe the condi-
tions of wheels or wheel stoppers outside the vehicle while the other is doing the test.
(1) Chock the 4 wheels.
(2) Connect an hand−held tester to the DLC3.
(3) Fully apply the parking brake.
(4) Keep your left foot pressed firmly on the brake pedal.
(5) Start the engine.
(6) Shift into the D position. Press all the way down on the accelerator pedal with your right foot.
(7) Quickly read the stall speed at this time.
Stall speed: 2,250á150 rpm
(8) Do the same test in the R position.
Stall speed: 2,250á150 rpm
Evaluation:
ProblemPossible cause
(a) Stall engine speed is low in D and R positions
SEngine power output may be insufficient
SStator one−way clutch not operating properly
HINT: If the value is less than the specified value by 600 rpm or
more, the torque converter could be faulty.
(b) Stall engine speed is high in D position
SLine pressure is too low
SForward clutch slipping
SU/D (Underdrive) brake slipping
SU/D (Underdrive) one−way clutch not operating properly
SNo.1one−way clutch not operating properly
(c) Stall engine speed is high in R position
SLine pressure is too low
SReverse clutch slipping
S1st and reverse brake slipping
SU/D (Underdrive) brake slipping
(d) Stall engine speed is high in D and R positionsSLine pressure is too low
SImproper fluid level
