Fuel Injector Operation Inspection

If simulation function of M-MDS is used:

ENGINE CONTROL SYSTEM OPERATION INSPECTION (SKYACTIV-G) FUEL INJECTOR OPERATION INSPECTION

Step	INSPECTION		ACTION
1	Start the engine and warm it up completely. Access the PCM PID [INJ] using the M-MDS. (See PID/DATA MONITOR INSPECTION .) Turn each fuel injector from on to off using the PIDs for each cylinder. Does the engine speed drop?	Yes	Fuel injectors work properly.
1		No	Engine speed does not drop an any cylinder: Go to the next step. Engine speed drops on some cylinders: Go to Step 4.
2	Perform the Main Relay Operation Inspection. (See MAIN RELAY OPERATION INSPECTION .) Does the main relay work properly?	Yes	Go to the next step.
2		No	Repair or replace the malfunctioning part according to the inspection results.
3	Inspect the fuel injector of the suspected cylinder. (Refer to FUEL INJECTOR INSPECTION [SKYACTIV-G 2.0] in service information.) Is there any malfunction?	Yes	Replace the fuel injector. (Refer to FUEL INJECTOR REMOVAL/INSTALLATION [SKYACTIV-G 2.0] in service information.)
3		No	Inspect the fuel injector power and/or ground systems related wiring harness and connectors for the suspected cylinder. If all items normal: Replace the PCM. (Refer to PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.0] in service information.) If not: Repair or replace the malfunctioning part according to the inspection results.
4	Perform the KOER self test using the M-MDS. (See DTC INSPECTION .) Are the DTCs P0201:00, P0202:00, P0203:00 and/or P0204:00 present?	Yes	Go to the appropriate DTC inspection. (See P0201:00 [PCM (SKYACTIV-G)] .) (See P0202:00 [PCM (SKYACTIV-G)] .) (See P0203:00 [PCM (SKYACTIV-G)] .) (See P0204:00 [PCM (SKYACTIV-G)] .)
4		No	Go to the next step.
5	Inspect the fuel injector of the suspected cylinder. (Refer to FUEL INJECTOR INSPECTION [SKYACTIV-G 2.0] in service information.) Is there any malfunction?	Yes	Replace the fuel injector. (Refer to FUEL INJECTOR REMOVAL/INSTALLATION [SKYACTIV-G 2.0] in service information.)
5		No	Inspect the following for the suspected cylinder: PCM terminals (pulled-out pins, corrosion) Fuel injector terminals (pulled-out pins, corrosion) If all items normal: Replace the PCM. (Refer to PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.0] in service information.) If not: Repair or replace the malfunctioning part according to the inspection results.
