CHECKING COMPRESSION PRESSURE
1. Warm up engine thoroughly. Then, stop it.
2. Using CONSULT-II, make sure no error codes are indicated for self-diagnosis items. Refer to EC-905,
"Basic Inspection" (WITH EURO-ODB) or EC-1231, "Basic Inspection" (WITHOUT EURO-ODB).

Do not disconnect CONSULT-II until the end of this operation; it will be used to check engine rpm and
for error detection at the end of this operation.
3. Disconnect the negative battery terminal.
4. Remove charge air cooler. Refer to EM-135, "
Removal and Installation"
5. To prevent fuel from being injected during inspection, remove
fuel pump fuse [ENG CONT 2 (20A)] from fuse box on the left
side of engine room.

Among marks on fuse box, [ENG CONT 2 (20A)] is for fuel
pump fuse.
6. Remove glow plugs from all the cylinders. Refer to EM-152,
"Removal and Installation" .
CAUTION:

Before removal, clean the surrounding area to prevent
entry of any foreign materials into engine.

Carefully remove glow plugs to prevent any damage or
breakage.

Handle with care to avoid applying any shock to glow plugs.
7. Install compression gauge adapter (special service tool) to
installation holes of glow plugs and connect compression gauge
for diesel engine.
8. Connect battery negative terminal.
9. With accelerator pedal fully depressed, turn ignition switch to
“START” for cranking. When the gauge pointer stabilizes, read
the compression pressure and engine rpm. Perform these steps
to check each cylinder.

Always use a fully-charged battery to obtain specified engine
speed.
Compression pressure
Unit: kPa (bar, kg/cm2 , psi)/rpm

When engine rpm is out of the specified range, check the specific gravity of battery liquid. Measure
again under corrected conditions.

If engine rpm exceeds the limit, check valve clearance and combustion chamber components (valves,
valve seats, cylinder head gaskets, piston rings, pistons, cylinder bores, cylinder block upper and lower
surfaces) and measure again.

If compression pressure is low in some cylinders, apply engine oil from glow plug installation hole. Then
check pressure again.
–If compression pressure becomes normal after applying engine oil, piston ring may be worn or dam-
aged. Check piston ring for malfunction. If any, replace piston ring.
–If compression pressure is still low after applying engine oil, valve may be malfunctioning. Check valve
for malfunction. If contact malfunction is found, replace valve or valve seat.

If compression pressure in adjacent two cylinders is low after applying engine oil, pressure may be
leaking from gasket. In this case, replace cylinder head gasket.

4. After installing cylinder head, measure dimension from the front
end surface of cylinder block to that of cylinder head.

If out of the standard, check fitting of dowel pins and cylinder
head.
5. Install glow plug.
CAUTION:

To avoid damage, glow plugs should be removed only when required.

BASIC SERVICE PROCEDURE

12. Rev up the engine two or three times and make sure that idle speed and ignition timing are within the
specifications.
13. If idle speed and ignition timing are not within the specification, Idle Air Volume Learning will not be carried
out successfully. In this case, find the cause of the incident by referring to the DIAGNOSTIC PROCE-
DURE below.
DIAGNOSTIC PROCEDURE
If idle air volume learning cannot be performed successfully, proceed as follows:
1.Check that throttle valve is fully closed.
2.Check PCV valve operation.
3.Check that downstream of throttle valve is free from air leakage.
4.When the above three items check out OK, engine component parts and their installation condi-
tion are questionable. Check and eliminate the cause of the incident.
It is useful to perform EC-119, "
TROUBLE DIAGNOSIS - SPECIFICATION VALUE" .
5.If any of the following conditions occur after the engine has started, eliminate the cause of the
incident and perform Idle Air Volume Learning all over again:

Engine stalls.

Erroneous idle.
Fuel Pressure CheckEBS010LI
FUEL PRESSURE RELEASE
With CONSULT-II
1. Turn ignition switch ON.
2. Perform “FUEL PRESSURE RELEASE” in “WORK SUPPORT”
mode with CONSULT-II.
3. Start engine.
4. After engine stalls, crank it 2 or 3 times to release all fuel pres-
sure.
5. Turn ignition switch OFF.
Without CONSULT-II
1. Remove fuel pump fuse located in fuse box.
2. Start engine.
3. After engine stalls, crank it 2 or 3 times to release all fuel pres-
sure.
4. Turn ignition switch OFF.
5. Reinstall fuel pump fuse after servicing fuel system.
FUEL PRESSURE CHECK
Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.
