Function Inspection Using M-MDS

STEP	INSPECTION	RESULTS	ACTION
1	PURPOSE: VERIFY RELATED SERVICE INFORMATION AVAILABILITY •  Verify related Service Information availability. •  Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. •  If the vehicle is not repaired, go to the next step.
		No	Go to the next step.
2	PURPOSE: RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION •  Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?	Yes	Go to the troubleshooting procedure to perform the procedure from Step 1.
		No	Record the FREEZE FRAME DATA (Mode 2)/snapshot data on the repair order. Note •  Recording can be facilitated using the screen capture function of the PC. Go to the troubleshooting procedure to perform the procedure from Step 1.

Troubleshooting Diagnostic Procedure

―  Perform an inspection of the A/F sensor and PCM-related connectors.

―  Perform an inspection of the short to power supply in wiring harness between A/F sensor and PCM.

―  Perform a unit inspection of the A/F sensor.

―  Verify that the primary malfunction is resolved and there are no other malfunctions.

STEP	INSPECTION	RESULTS	ACTION
1	PURPOSE: INSPECT A/F SENSOR CONNECTOR CONDITION •  Switch the ignition off. •  Disconnect the A/F sensor connector. •  Inspect for poor connection (such as damaged/pulled-out pins, corrosion). •  Is there any malfunction?	Yes	Replace the A/F sensor, then go to Step 5. (See AIR FUEL RATIO (A/F) SENSOR REMOVAL/INSTALLATION [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].)
		No	Go to the next step.
2	PURPOSE: INSPECT PCM CONNECTOR CONDITION •  Disconnect the PCM connector. •  Inspect for poor connection (such as damaged/pulled-out pins, corrosion). •  Is there any malfunction?	Yes	Replace the PCM, then go to Step 5. (See PCM REMOVAL/INSTALLATION [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].)
		No	Go to the next step.
3	PURPOSE: INSPECT A/F SENSOR CIRCUIT FOR SHORT TO POWER SUPPLY •  Verify that the A/F sensor and PCM connectors are disconnected. •  Switch the ignition ON (engine off). Note •  Another DTC may be stored by the PCM detecting an open circuit. •  Measure the voltage at the following terminals (wiring harness-side): ―  A/F sensor terminal F ―  A/F sensor terminal D ―  A/F sensor terminal B •  Is the voltage 0 V?	Yes	Go to the next step.
		No	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: •  A/F sensor terminal F—PCM terminal 1W •  A/F sensor terminal D—PCM terminal 1AB •  A/F sensor terminal B—PCM terminal 1AG If there is a common connector: •  Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply. •  Repair or replace the malfunctioning part. If there is no common connector: •  Repair or replace the wiring harness which has a short to power supply. Go to Step 5.
4	PURPOSE: DETERMINE INTEGRITY OF A/F SENSOR •  Start the engine and warm it up completely. •  Access the O2S11 PID using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].) •  Drive the vehicle under the following conditions. Warning •  When the M-MDS is used to observe monitor system status while driving, be sure to have another technician with you, or record the data in the M-MDS using the PID/DATA MONITOR AND RECORD capturing function and inspect later. •  While performing this step, always operate the vehicle in a safe and lawful manner. ―  After increasing the engine speed to 3,000 rpm, decelerate using engine braking. •  Is the displayed PID value as follows? ―  O2S11: 0.25 mA or more	Yes	Go to the next step.
		No	Replace the A/F sensor, then go to the next step. (See AIR FUEL RATIO (A/F) SENSOR REMOVAL/INSTALLATION [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].)
5	PURPOSE: VERIFICATION OF VEHICLE REPAIR COMPLETION •  Always reconnect all disconnected connectors. •  Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].) •  Perform the KOER self test. (See KOEO/KOER SELF TEST [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].) •  Is the PENDING CODE for this DTC present?	Yes	Repeat the inspection from Step 1. •  If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].) Go to the next step.
		No	Go to the next step.
6	PURPOSE: VERIFY IF THERE IS ANY OTHER MALFUNCTION •  Is any other DTC or pending code stored?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].)
		No	DTC troubleshooting completed.
