1. Warm up engine.
2. Turn ignition switch OFF.
3. Release fuel pressure.
Refer to EC-40, ªReleasing Fuel Pressureº.
4. Remove ignition coils.
5. Remove spark plugs.
+Clean area around plug with compressed air before removing
the spark plug.

6. Attach a compression tester to No. 1 cylinder.
7. Depress accelerator pedal fully to keep throttle valve wide
open.
8. Crank engine and record highest gauge indication.
9. Repeat the measurement on each cylinder as shown above.
+Always use a fully-charged battery to obtain specified
engine speed.

10. If cylinder compression in one or more cylinders is low, pour a
small amount of engine oil into the cylinder through the spark
plug hole and retest compression.
+If adding oil improves cylinder compression, piston rings
may be worn or damaged. If so, replace piston rings after
checking piston.
+If pressure stays low, a valve may be sticking or seating
improperly. Inspect and repair valve and valve seat. Refer
to SDS, EM-71. If valve or valve seat is damaged
excessively, replace them.
+If compression in any two adjacent cylinders is low and if add-
ing oil does not improve compression, there is leakage past the
gasket surface. If so, replace cylinder head gasket.
11. Reinstall spark plugs, ignition coils and fuel pump fuse.
12. Perform ªSelf-diagnosis Procedureº referring to EC-70, ªHow
to Erase DTCº if any DTC appears.

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-10, ªTrouble Diagnosis Ð
INDEXº.
+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.

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 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.

+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 ªOFFº.
b. Disconnect battery negative terminal.
