ENGINE TUNE-UP [SKYACTIV-X 2.0]
id0110hf800600
Engine Tune-up Preparation
1. Connect the M-MDS to the DLC-2.
2. Verify the following.
3. Maintain the engine speed at 2,500 to 3,000 rpm and warm up the engine. (Engine coolant temperature is 80 °C {176 °F} or more, oil temperature is 60 °C {140 °F}or more)
4. Turn off all electrical loads with the engine idling.
5. If the cooling fan is running, wait until it stops running.
Idle Speed Verification
1. Perform the preparations for the engine tune-up. (See Engine Tune-up Preparation)
2. Verify that the idle speed (PID: ENG_RPM) is within the standard using the M-MDS data monitor function. (See PID/DATA MONITOR INSPECTION.)(See PID/DATA MONITOR TABLE [PCM (SKYACTIV-X)].)
Ignition Timing Verification
1. Perform the preparations for the engine tune-up. (See Engine Tune-up Preparation)
2. Verify the ignition timing (PID: SPARK_ADV) using the M-MDS data monitor function. (See PID/DATA MONITOR INSPECTION.)(See PID/DATA MONITOR TABLE [PCM (SKYACTIV-X)].)
3. Increase the engine speed gradually and verify that the ignition timing advances.
Idle CO and HC Concentration Verification
1. Verify that the idle speed and ignition timing are within the standard. (See Idle Speed Verification)(See Ignition Timing Verification)
2. Set up the CO, HC tester.
3. Verify that the CO and HC concentrations are within the standard.
Idle Increase Control Verification
1. Perform the preparations for the engine tune-up. (See Engine Tune-up Preparation)
2. Verify that the idle speed according to each load (PID: ENG_RPM) is within the standard using the M-MDS data monitor function. (See PID/DATA MONITOR INSPECTION.)(See PID/DATA MONITOR TABLE [PCM (SKYACTIV-X)].)
