*1: Value can be verified by displaying the PIDs using the M-MDS.
Malfunction determination period
•  0.1 s period
Drive cycle
•  1
Self test type
•  CMDTC self test, KOER self test
Sensor used
•  PCM
FAIL-SAFE FUNCTION
•  Not applicable.
VEHICLE STATUS WHEN DTCs ARE OUTPUT
•  Illuminates the check engine light
POSSIBLE CAUSE
•  PCM malfunction


System Wiring Diagram

•  Not applicable.

Function Explanation (DTC Detection Outline)

•  If there is communication error between the A/F signal control driver and the CPU, the PCM stores a DTC.

Repeatability Verification Procedure

1.  Warm up the engine to allow the engine coolant temperature to reach 80 °C {176 °F} or more.
2.  Start the engine and leave it idling for 1 min.
Note
•  Match the engine coolant temperature in the recorded FREEZE FRAME DATA (Mode 2)/snapshot data, the vehicle speed, and engine speed values to the best extent possible while driving the vehicle.
3.  Try to reproduce the malfunction by driving the vehicle for 5 min based on the values in the FREEZE FRAME DATA (Mode 2)/snapshot data.

PID Item/Simulation Item Used In Diagnosis

•  Not applicable.

Troubleshooting Diagnostic Procedure

Intention of troubleshooting procedure
•  Step 1
―  Verify if malfunctioning part is PCM.
•  Step 2
―  Verify that there are no other malfunctions.

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: PERFORM DTC INSPECTION AND VERIFY IF MALFUNCTIONING PART IS PCM
•  Clear the DTC from the PCM memory using the M-MDS.
•  Perform the KOER self test.
•  Is the same DTC present?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5].)
No
Go to the next step.
3
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 [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)
No
DTC troubleshooting completed.
