PREPARATIONZD
Special Service Tools (Cont'd)
EM-1005

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.

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.
