DESCRIPTION
A water draining cock is on the lower side and a priming pump for bleeding air is on the upper side.
AIR BLEEDING
Pump the priming pump (1) to bleed air.
lWhen air is bled completely, the pumping of the priming pump
suddenly becomes heavy. Stop the operation at that time.
lIf it is difficult to bleed air by the pumping of the priming pump
(the pumping of the priming pump does not become heavy), dis-
connect the fuel supply hose between the fuel filter and the fuel
gallery. Then, perform the operation described above, and make
sure that fuel comes out. (Use a pan, etc. so as not to spill fuel.
Do not let fuel get on engine and other parts.) After that, connect
the hose, then bleed air again.
lStart engine and let it idle for at least 1 minute after performing
air bleeding.
WATER DRAINING
1. Remove the fuel filter, filter bracket, protector assembly from the dash panel as follows.
a. Remove the air cleaner case (upper), air duct assembly, and vacuum hose for brake booster (between the
vacuum pump and vacuum pipe).
CAUTION:
After the duct is removed, cover the opening with gum tape, etc. to prevent foreign object from
getting into the engine during the operation.
b. Remove the mounting nuts on the dash panel, then remove the fuel filter, filter bracket, and protector
assembly from the dash panel.
lIt is not necessary to disconnect the fuel hose.
2. Using a tool such as a pliers, loosen the water draining cock at
the bottom of the fuel filter.
Loosening drain cock four to five turns causes water to
start draining.
Do not remove drain cock by loosening it excessively.
If water dose not drain properly, move the priming up and down.
CAUTION:
When the water is drained, the fuel is also drained. Use a
pan, etc. to avoid fuel adherence to the rubber parts such as
the engine mount insulator.
Do not over-tighten the water draining cock. This will dam-
age the cock thread, resulting in water or fuel leak.
3. Bleed air of the fuel filter. Refer toEC-23, "
AIR BLEEDING".
4. Start the engine.

TROUBLE DIAGNOSIS
Basic Inspection
EBS01KCV
Precaution:
Perform Basic Inspection without electrical or mechanical loads applied;
lHeadlamp switch is OFF.
lOn vehicles equipped with daytime light systems, set lighting switch to the 1st position to light
only small lamps.
lAir conditioner switch is OFF.
lHeater fan switch is OFF.
lRear defogger switch is OFF.
lHeat up switch is OFF.
lSteering wheel is in the straight-ahead position, etc.
1.INSPECTION START
1. Check service records for any recent repairs that may indicate a related incident.
2. Check the current need for scheduled maintenance, especially for fuel filter and air cleaner filter. Refer to
MA-8, "
PERIODIC MAINTENANCE".
3. Open engine hood and check the following:
–Harness connectors for improper connections
–Vacuum hoses for splits, kinks, or improper connections
–Wiring for improper connections, pinches, or cuts
4. Start engine and warm it up to the normal operating tempera-
ture.
>> GO TO 2.
2.PREPARATION FOR CHECKING IDLE SPEED
With CONSULT-II
Connect CONSULT-II to the data link connector.
Without CONSULT-II
Install diesel tacho tester to the vehicle.

INTAKE AIR CONTROL VALVE CONTROL SOLENOID VALVE
INTAKE AIR CONTROL VALVE CONTROL SOLENOID VALVE
PFP:16188
DescriptionEBS01KM5
Vibration when stopping the engine can be controlled by cutting
intake air right before the fuel is cut. The intake air control valve con-
trol solenoid valve (1) controls the ON-OFF load of the intake air
control valve actuator. As a result, the intake air control valve control
solenoid valve will be turned ON when the ignition switch is turned
OFF with the engine running and when the engine stalls. After the
engine has stopped, the intake air control valve control solenoid
valve will return to fully open.

ECM Terminals and Reference ValueEBS01KM6
Specification data are reference valves, and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may damage the
ECM's transistor. Use a ground other than ECM terminals, such as the ground.
