1.Before inspection, check
that the engine oil, starter and battery are normal. In
addition,
set the vehicle to the pre-inspection condition. |
2.Remove the EGR
pipe. |
3.Remove all of the glow
plugs. |
6.Set compression gauge to
one of the glow plug holes. 7.Crank the engine and measure the compression pressure. Standard value (at engine speed of 280 r/min): 2,800 kPa Limit (at engine speed of 280 r/min): min. 2,500 kPa 8.Measure the compression pressure for all the cylinders, and check that the pressure differences of the cylinders are below the limit. Limit: max 300 kPa 9.If there is a cylinder with compression or a compression difference that is outside the limit, pour a small amount of engine oil through the glow plug hole, and repeat the operations in steps 7 and 8. (1) If the compression increases after oil is added, the cause of the malfunction is a worn or damaged piston ring and/or cylinder inner surface. (2) If the compression does not rise after oil is added, the cause is a burnt or defective valve seat, or pressure is leaking from the gasket. 10.Connect the crank angle sensor connector. 11.Install the glow plugs. Tightening torque: 17 ± 2 N·m 12.Install the EGR pipe. |
13.Use the M.U.T.-III to
erase the diagnosis codes.
