JEM111G
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-39, “CONSULT-II Inspection
Procedure”.
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.
4. Disconnect the negative battery terminal.
5. To prevent fuel from being injected during inspection, remove
fuel injection pump fuse [ENG CONT2 (20A)] from fuse box on
the left side of engine compartment.
6. 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.
SEM112G
7. Install adapter (SST) to installation holes of glow plugs and
connect compression gauge for diesel engine.
: 18 - 21 N·m (1.8 - 2.2 kg-m, 13 - 15 ft-lb)
8. Connect battery negative terminal.
9. Set the ignition switch to “START” 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
3,138 (31.38, 32.0, 455)/
2002,452 (24.52, 25.0, 356)/
200490 (4.90, 5.0, 71)/200
When engine rpm is out of the specified range, check the spe-
cific 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, cylin-
der head gaskets, piston rings, pistons, cylinder bores, cylin-
der block upper and lower surfaces) and measure again.
10. Complete this operation as follows:
a. Turn the ignition switch to “OFF”.
b. Disconnect battery negative terminal.
c. Install glow plugs.

BASIC SERVICE PROCEDURE
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-105, "
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 CheckEBS00K3E
FUEL PRESSURE RELEASE
Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.
NOTE:
Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel pres-
sure cannot be completely released because N16 models do not have fuel return system.
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 two or three times to release all fuel
pressure.
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 two or three times to release all fuel
pressure.
4. Turn ignition switch “OFF”.
5. Reinstall fuel pump fuse after servicing fuel system.
FUEL PRESSURE CHECK
NOTE:
●When reconnecting fuel line, always use new clamps.
●Make sure that clamp screw does not contact adjacent parts.
●Use a torque driver to tighten clamps.
●Use Pressure Gauge to check fuel pressure.
1. Release fuel pressure to zero. Refer to EC-34, "
FUEL PRESSURE RELEASE" .
