Diagnostic Procedure

Step

Inspection

Results

Action
1
IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA
• Is the DTC P011A:00 on freeze frame data?
Yes
Go to the next step.
No
Go to the troubleshooting procedure for DTC on freeze frame data.
(See DTC TABLE [PCM (SKYACTIV-G (US))].)
2
RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION
• Record the freeze frame data/snapshot data.

Note
• Recording can be facilitated using the screen capture function of the PC.
—
Go to the next step.
3
VERIFY RELATED REPAIR INFORMATION OR SERVICE INFORMATION AVAILABILITY
• Verify related Service Bulletins, on-line repair information, or Service Information availability.
• Is any related Information available?
Yes
Perform repair or diagnosis according to the available information.
• If the vehicle is not repaired, go to the next step.
No
Go to the next step.
4
INSPECT ECT SENSOR No.1 CONNECTOR FOR MALFUNCTION
• Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION.)
• Are the connector and terminal normal?
Yes
Go to the next step.
No
Repair or replace the malfunctioning location and perform the repair completion verification.
5
INSPECT ECT SENSOR No.2 CONNECTOR FOR MALFUNCTION
• Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION.)
• Are the connector and terminal normal?
Yes
Go to the next step.
No
Repair or replace the malfunctioning location and perform the repair completion verification.
6
INSPECT PCM CONNECTOR FOR MALFUNCTION
• Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION.)
• Are the connector and terminal normal?
Yes
Go to the next step.
No
Repair or replace the malfunctioning location and perform the repair completion verification.
7
INSPECT ECT SENSOR No.1 FOR MALFUNCTION
• Inspect the applicable part. (See ENGINE COOLANT TEMPERATURE (ECT) SENSOR INSPECTION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See ENGINE COOLANT TEMPERATURE (ECT) SENSOR INSPECTION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
• Is the part normal?
Yes
Go to the next step.
No
Repair or replace the malfunctioning location and perform the repair completion verification.
(See ENGINE COOLANT TEMPERATURE (ECT) SENSOR REMOVAL/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].)
(See ENGINE COOLANT TEMPERATURE (ECT) SENSOR REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)

Repair completion verification 1
VERIFY THAT VEHICLE IS REPAIRED
• Install/connect the part removed/disconnected during the troubleshooting procedure.
• Clear the DTC recorded in the memory. (See CLEARING DTC.)
• Replicate the vehicle conditions at the time the DTC was detected using the following procedure.
― Switch the ignition off.
― Start the engine and warm it up completely.
• Perform the DTC inspection for the PCM. (See DTC INSPECTION.)
• Is the same Pending DTC present?
Yes
Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.
(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(US)].)
If the CAN communication is normal, perform the diagnosis from Step 1.
• If the malfunction recurs, replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See PCM REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
No
Go to the next step.
Repair completion verification 2
VERIFY IF OTHER DTCs DISPLAYED
• Perform the DTC inspection. (See DTC INSPECTION.)
• Are any other DTCs displayed?
Yes
Repair the malfunctioning location according to the applicable DTC troubleshooting.
No
DTC troubleshooting completed.
