ECM Terminals and Reference Value
Specification data are reference values 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.

On Board Diagnosis Logic
This diagnosis continuously monitors the engine coolant temperature.
If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise.
When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction is
indicated.
Malfunction is detected when ... Check Items (Possible Cause)
+Cooling fan does not operate properly (Overheat).
+Cooling fan system does not operate properly (Overheat).
+Engine coolant was not added to the system using the proper
filling method.+Harness or connectors
(The cooling fan circuit is open or shorted.)
+Cooling fan
+Radiator hose
+Radiator
+Radiator cap
+Water pump
+Thermostat
+Fan belt
+Engine coolant temperature sensor
For more information, refer to ªMAIN 12 CAUSES OF
OVERHEATINGº, EC-1116.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant following the procedure in the MA
section (ªChanging Engine Coolantº, ªENGINE MAINTENANCEº). Also, replace the engine oil.
1) Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure
to use coolant with the proper mixture ratio. Refer to MA section (ªAnti-freeze Coolant Mixture
Ratioº, ªRECOMMENDED LUBRICANTS AND FLUIDSº).
2) After refilling coolant, run engine to ensure that no water-flow noise is emitted.

Parts Requiring Angular Tightening
+Use an angle wrench for the final tightening of the cylinder
head bolts.
+Do not use a torque value for final tightening.
+The torque value for these parts are for a preliminary step.
+Ensure thread and seat surfaces are clean and coated with
engine oil.
Liquid Gasket Application Procedure
1.Use a scraper to remove old liquid gasket from mating
surfaces and grooves. Also, completely clean any oil
from these areas.
2.Apply a continuous bead of liquid gasket to mating sur-
faces. (Use Genuine Liquid Gasket or equivalent.)
+Be sure liquid gasket diameter is as specified.
3.Apply liquid gasket around the inner side of bolt holes
(unless otherwise specified).
4.Assembly should be done within 5 minutes after coating.
5.Wait at least 30 minutes before refilling engine oil and
engine coolant.

TROUBLESHOOTINGZD
EM-1009

1. Warm up engine.
2. Turn ignition switch OFF.
3.
Using CONSULT-II, make sure no error codes are indicated for
self-diagnosis items. Refer to EC section, ªFuel Pressure
Releaseº.
+Do not disconnect CONSULT-II until the end of this opera-
tion; it will be used to check engine rpm and for error detec-
tion at the end of this operation.
4. Disconnect the negative battery terminal.
5. Remove the following parts.
+Intercooler cover
+Intercooler
+Throttle body
+Rocker cover
6. To prevent fuel from being injected during inspection, remove
fuel injection pump fuse [ENG CONT (20A)] from fuse box on
the right side of engine compartment.
7. Remove glow plugs from all the cylinders.
+Before removal, clean the surrounding area to prevent
entry of any foreign materials into the engine.
+Carefully remove glow plugs to prevent any damage or
breakage.
+
Handle with care to avoid applying any shock to glow plugs.
8. Install adapter (SST) to installation holes of glow plugs and
connect compression gauge for diesel engine.
:15-19Nzm (1.5 - 2.0 kg-m, 11 - 14 ft-lb)
9. Connect battery negative terminal.
10. Set the ignition switch to ªSTARTº and crank. When gauge
pointer stabilizes, read compression pressure and engine
rpm. Repeat the above steps for each cylinder.
+Always use a fully-charged battery to obtain specified
engine speed.
Unit: kPa (bar, kg/cm2, psi)/rpm
Standard MinimumDifference limit between
cylinders

2002,452 (24.52, 25.0, 356)/
200294 (2.94, 3.0, 43)/200
+When engine rpm is out of the specified range, check the
specific gravity of battery liquid. Measure again under cor-
rected conditions.
+If engine rpm exceeds the limit, check valve clearance and
combustion chamber components (valves, valve seats, cyl-
inder head gaskets, piston rings, pistons, cylinder bores, cyl-
inder block upper and lower surfaces) and measure again.
11. Complete this operation as follows:
a. Turn the ignition switch to ªOFFº.
b. Disconnect battery negative terminal.
c. Replace glow plug oil seals and install glow plugs.
d. Install fuel injection pump fuse [ENG CONT (20A)].
e. Connect battery negative terminal.
f. Using CONSULT-II make sure no error code is indicated for
items of self-diagnosis. Refer to EC section, ªTrouble Diag-
nosis Ð Indexº.

Trouble diagnosis of turbocharger
Preliminary check:
Check that the VNT control valve system has no malfunction.
Refer to EC section, ªECM Terminals and Reference Valueº in
ªTROUBLE DIAGNOSIS Ð GENERAL DESCRIPTIONº.
+Check that the engine oil level is between MIN and MAX of
the dipstick. (When the engine oil amount is more than MAX,
the oil flows into the inlet duct through the blow-by gas
passage, and the turbocharger is misjudged failure.)
+Ask the customer if he/she always runs the vehicle in idle
engine speed to cool the oil down after driving.
+Replace the turbocharger assembly when any malfunction is
found after unit inspections specified in the table below.
+If no malfunction is found after the unit inspections, judge that
the turbocharger body has no failure. Check the other parts
again.

Place the protruding area of the gasket between the turbo-
charger and the exhaust outlet upwards, and install the lipped
side to the turbocharger side. Refer to the figure, EM-1014.
