Warning<\/div>\n<\/dd>\n
\n
\n
\u2022 Hot engines and oil can cause severe burns. Be careful not to burn yourself during removal\/installation of each component.<\/div>\n
\u2022 Fuel vapor is hazardous. It can very easily ignite, causing serious injury and damage. Always keep sparks and flames away from fuel.<\/div>\n
\u2022 Highly pressurized fuel may spray out if the fuel line is cut. Due to the following dangers occurring with a fuel spray, always complete the \u201cFuel Line Safety Procedure\u201d to prevent the fuel from spraying.<\/div>\n
\n
\n
\u2015 Fuel may cause irritation if it comes in contact with skin and eyes.<\/div>\n
\u2015 If fuel ignites and causes a fire, it may lead to serious injury or death, and damage to property and facilities.<\/div>\n<\/dd>\n<\/dl>\n<\/div>\n<\/dd>\n<\/dl>\n

1.Verify that the battery is fully charged. (See BATTERY INSPECTION [(US)]<\/a>.)<\/p>\n

\n

2.Connect the M-MDS to the DLC-2.<\/p>\n

\n

3.Warm up the engine to the normal operating temperature.<\/p>\n

\n

4.Display the following PIDs using the M-MDS data monitor function. (See PCM INSPECTION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))]<\/a>.)<\/p>\n

\n

\n
\n
\u2022 RPM (engine speed)<\/div>\n<\/dd>\n<\/dl>\n

5.Perform the \u201cFuel Line Safety Procedure\u201d to remove the fuel pump relay. (See BEFORE SERVICE PRECAUTION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))]<\/a>.)<\/p>\n

\n

6.Remove the following parts.<\/p>\n

\n

\n
(1)Plug hole plate. (See PLUG HOLE PLATE REMOVAL\/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))]<\/a>.)<\/dd>\n
<\/dd>\n<\/dl>\n
\n
(2)Ignition coil\/ion sensors. (See IGNITION COIL\/ION SENSOR REMOVAL\/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))]<\/a>.)<\/dd>\n
<\/dd>\n<\/dl>\n
\n
(3)Spark plugs. (See SPARK PLUG REMOVAL\/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))]<\/a>.)<\/dd>\n
<\/dd>\n<\/dl>\n
\n
(4)Fuel injector relay<\/dd>\n
<\/dd>\n<\/dl>\n

7.Measure the compression pressure using the following procedure.<\/p>\n

\n

\n
(1)Install the compression gauge to the spark plug hole.<\/dd>\n
<\/dd>\n<\/dl>\n
\n
(2)Fully depress the accelerator pedal.<\/dd>\n
\n
\n
\n
Note<\/div>\n<\/dd>\n
\n
\n
\u2022 The cranking method is as follows.<\/div>\n
\n
\n
MTX<\/div>\n<\/dd>\n
\n
\u2015 When the ignition switch is pressed with the clutch pedal depressed, cranking starts.<\/div>\n
\u2015 When your foot is removed from the clutch pedal during cranking, cranking stops.<\/div>\n
\u2015 When the ignition switch is pressed during cranking, cranking stops.<\/div>\n<\/dd>\n<\/dl>\n
\n
\n
ATX<\/div>\n<\/dd>\n
\n
\u2015 When the ignition switch is pressed with the brake pedal depressed, cranking starts.<\/div>\n
\u2015 When the ignition switch is pressed during cranking, cranking stops.<\/div>\n<\/dd>\n<\/dl>\n<\/div>\n<\/dd>\n<\/dl>\n<\/dd>\n<\/dl>\n
\n
(3)Crank the engine and measure the following values simultaneously.<\/dd>\n
\n
\n
\n
\u2022 Compression pressure<\/div>\n
\u2022 Engine speed<\/div>\n<\/dd>\n<\/dl>\n

\n
\n
Note<\/div>\n<\/dd>\n
\n
\u2022 Because the SKYACTIV-G 2.0 and SKYACTIV-G 2.5 retards the intake valve closing timing, compression pressure is low.<\/div>\n<\/dd>\n<\/dl>\n<\/dd>\n<\/dl>\n
\n
(4)Perform Steps (1) to (3) for all cylinders.<\/dd>\n
<\/dd>\n<\/dl>\n
\n
(5)If the measured value is the threshold or less, or if there is a cylinder which exceeds the specified maximum difference between cylinders, add a small amount of engine oil through the spark plug hole and perform Steps (1) to (3).<\/dd>\n
\n
\n
\n
\u2022 If the pressure increases by adding the engine oil, the piston ring or the cylinder surface is worn, or they are damaged. Perform overhaul servicing.<\/div>\n<\/dd>\n<\/dl>\n
\n
\n
\u2022 If the pressure does not increase, valve seizure, valve attachment malfunction, or pressure leakage from the cylinder head gasket might be occurring. Perform overhaul servicing.<\/div>\n<\/dd>\n<\/dl>\n<\/dd>\n<\/dl>\n
\n
(6)If the measured value is high, it is possible that there is an error in the electric variable valve timing system.<\/dd>\n
<\/dd>\n<\/dl>\n

8.Remove the compression gauge.<\/p>\n

\n

9.Install the following parts.<\/p>\n

\n

\n
(1)Fuel injector relay<\/dd>\n
<\/dd>\n<\/dl>\n
\n
(2)Spark plugs. (See SPARK PLUG REMOVAL\/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))]<\/a>.)<\/dd>\n

\n
(4)Plug hole plate. (See PLUG HOLE PLATE REMOVAL\/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))]<\/a>.)<\/dd>\n
<\/dd>\n<\/dl>\n

10.Install the fuel pump relay. (See BEFORE SERVICE PRECAUTION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))]<\/a>.)<\/p>\n
