1.Before inspection, check
that the engine oil, starter and battery are normal. In
addition,
set the vehicle to the pre-inspection condition. |
2.Turn the ignition switch
to "LOCK" (OFF) position. |
3.Remove the inlet manifold
(Refer to GROUP 15 - Inlet Manifold ![]() |
4.Remove all of the glow
plugs (Refer to GROUP 16 - Glow System, Glow Plug ![]() |
![]() |
7.Set compression gauge to
one of the glow plug holes. 8.Crank the engine and measure the compression pressure. Standard value (at engine speed of 250 r/min):
<High power engine> 2,400 kPa
<High power engine> Minimum 1,650 kPa Limit: Maximum 300 kPa 10.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 9. (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. 11.Connect the crank angle sensor connector. 12.Install the glow plugs (Refer to GROUP 16 - Glow System, Glow Plug ![]() 13.Install the inlet manifold (Refer to GROUP 15 - Inlet Manifold ![]() 14.Turn the ignition switch to the "LOCK" (OFF) position and then connect the M.U.T.-III to the diagnosis connector (Refer to GROUP 00 - Precautions Before Service, M.U.T.-III ![]() 15.Use the M.U.T.-III to erase the diagnosis codes.
