Notice
• Before cranking the engine, make sure that the test wiring, tools and persons are keeping away from moving
components of engine (e.g., belt and cooling fan).
• Park the vehicle on the level ground and apply the parking brake.
• Do not allow anybody to be in front of the vehicle.
Specifications
COMPRESSION PRESSURE TEST
The compression pressure test is to check the conditions of internal components (piston, piston ring, intake and
exhaust vale, cylinder head gasket). This test provides current engine operating status.

1. Warm the engine up to normal operating temperature
(80°C).
2. Disconnect the fuel rail pressure sensor connector to
cut off the fuel injection.
3. Place the diagram sheet to compression pressure tester.
Notice
•
Disconnect the fuel rail pressure sensor connector to cut off the fuel injection.
•
Discharge the combustion residues in the cylinders before testing the compression pressure.
•
Apply the parking brake before cranking the engine.
Measuring Procedure
4. Remove the glow plugs and install the compression
pressure tester into the plug hole.
5. Crank the engine for approx. 10 seconds by using the
start motor.
6. Record the test result and measure the compression
pressure of other cylinders with same manner.
7. If the measured value is not within the specifications,
perform the cylinder pressure leakage test.

If the measured value of the compression pressure test is not
within the specifications, perform the cylinder pressure leak-
age test.
Permissible Pressure Leakage
Notice
• Perform the pressure in order: 1 - 2 - 3 - 4 - 5
• Do not test the cylinder pressure leakage with wet type test procedure. (do not inject the engine oil into the
combustion chamber)
