ENGINE TUNE-UP [SKYACTIV-G (WITH CYLINDER DEACTIVATION (E))]
id0110u3800600
Engine Tune-up Preparation
1. Connect the M-MDS to the DLC-2.
2. Shift the selector lever (ATX) or shift lever (MTX) to the following position:
3. Run the engine speed at a constant 2,500 to 3,000 rpm and warm up the engine (engine coolant temperature: 80 °C {176 °F} or more, oil temperature: 60 °C {140 °F} or more).
4. Turn off all electrical loads with the engine idling.
5. If the cooling fan is operating, wait until is stops.
Idle Speed Inspection
1. Prepare for the engine tune-up. (See Engine Tune-up Preparation.)
2. Verify that the idle speed (M-MDS PID: ENG_RPM) is within the specification using the PID/data monitor function of the M-MDS. (See PCM INSPECTION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (E))].)
Ignition Timing Inspection
1. Prepare for the engine tune-up. (See Engine Tune-up Preparation.)
2. Verify the ignition timing (M-MDS PID: SPARK_ADV) using the PID/data monitor function of the M-MDS. (See PCM INSPECTION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (E))].)
3. Verify that ignition timing advances when the engine speed increases gradually.
Idle Mixture Inspection
1. Verify that the idle speed and ignition timing are within the specification. (See Idle Speed Inspection.) (See Ignition Timing Inspection.)
2. Insert an exhaust gas analyzer into the tailpipe.
3. Verify that the CO and HC concentrations are within regulation.
Idle-up Speed Control Inspection
1. Prepare for the engine tune-up. (See Engine Tune-up Preparation.)
2. Verify that the idle speed according to each load (M-MDS PID: ENG_RPM) is within the specification using the PID/data monitor function of the M-MDS (except idle speed decrease after applying load). (See PCM INSPECTION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (E))].)
