1.Before inspection, set the
vehicle to the pre-inspection condition. |
2.Disconnect the connector
of the ignition coil, and then remove all of the ignition
coils and spark plugs (Refer to GROUP 11B - Alternator
and Ignition System ![]() |
![]() |
5.Set compression gauge to
one of the spark plug holes. 6.Cranking the engine with the accelerator pedal fully depressed, measure the compression pressure. Standard value (at engine speed of 250 r/min):
Limit: Maximum 98 kPa 8.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 spark plug hole, and repeat the operations in steps from 5 to 7. (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. 9.Connect all of the injector connectors. 10.Install all of the spark plugs and ignition coils (Refer to GROUP 11B - Alternator and Ignition System ![]() 11.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 Sub Assembly ![]() 12.Use the M.U.T.-III to erase the diagnosis codes.
