HARNESS INDICATIONNJGI0003S0202+Letter designations next to test meter probe indicate harness
(connector) wire color.
+Connector numbers in a single circle M33 indicate harness
connectors.
COMPONENT INDICATIONNJGI0003S0203+Connector numbers in a double circle F211 indicate compo-
nent connectors.
SGI860
SWITCH POSITIONSNJGI0003S0204Switches are shown in wiring diagrams as if the vehicle is in the
ªnormalº condition.
A vehicle is in the ªnormalº condition when:
+ignition switch is ªOFFº,
+doors, hood and trunk lid/back door are closed,
+pedals are not depressed, and
+parking brake is released.
DETECTABLE LINES AND NON-DETECTABLE LINESNJGI0003S0205In some wiring diagrams, two kinds of lines, representing wires,
with different weight are used.
+A line with regular weight (wider line) represents a ªdetectable
line for DTC (Diagnostic Trouble Code)º. A ªdetectable line for
DTCº is a circuit in which ECM can detect its malfunctions with
the on board diagnostic system.
+A line with less weight (thinner line) represents a ªnon-detect-
able line for DTCº. A ªnon-detectable line for DTCº is a circuit
in which ECM cannot detect its malfunctions with the on board
diagnostic system.

1. Warm up engine.
2. Turn ignition switch OFF.
3. Release fuel pressure.
Refer to EC-38, 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-70. 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-68, ªHow
to Erase DTCº if any DTC appears.
