Step	Inspection	Results	Action
1	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.
2	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.
3	INSPECT FOR OTHER RELATED DTCs • Perform the DTC inspection for the PCM. (See DTC INSPECTION.) • Are any other DTCs displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [PCM (SKYACTIV-D)].)
No	Go to the next step.
4	INSPECT EFFECT OF VEHICLE USE CONDITION FOR CAUSE OF MALFUNCTION • Verify how the customer drives the vehicle by asking the customer the following: ― High engine speed maintained continuously for long period of time • Is the way the engine is being used producing excess heat?	Yes	Go to the next step.
No	Go to Step 6.
5	VERIFY IF MALFUNCTION IS CAUSED BY OVERHEATING Warning • To prevent an accident, work with another person when the vehicle is being driven (one person drives vehicle, other person operates M-MDS). • Observe legal speed limits when driving the vehicle and perform the procedure in a location where safety can be assured. • Display PID ECT using the M-MDS. (See DTC INSPECTION.) • Is the data monitor item ECT value 110 °C {230 °F} or more while the vehicle is driven on a flat road?	Yes	Explain to the customer that the vehicle is normal. Go to repair completion verification.
No	A malfunction due to overheating of the coolant system can be considered. • Perform malfunction diagnosis according to [COOLING SYSTEM CONCERNS-OVERHEATING ]. (See COOLING SYSTEM CONCERNS-OVERHEATING [SKYACTIV-D].)
6	INSPECT ECT SENSOR FOR MALFUNCTION • Inspect the applicable part. (See ENGINE COOLANT TEMPERATURE (ECT) SENSOR INSPECTION [SKYACTIV-D 1.8].) • 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-D 1.8].)
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. ― Start the engine and warm it up. ― Drive the vehicle. • 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 [(E)].) 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-D 1.8].)
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.

Go to the next step.

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.

Go to the next step.

INSPECT FOR OTHER RELATED DTCs

• Perform the DTC inspection for the PCM.

(See DTC INSPECTION.)

• Are any other DTCs displayed?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

(See DTC TABLE [PCM (SKYACTIV-D)].)

Go to the next step.

INSPECT EFFECT OF VEHICLE USE CONDITION FOR CAUSE OF MALFUNCTION

• Verify how the customer drives the vehicle by asking the customer the following:

― High engine speed maintained continuously for long period of time

• Is the way the engine is being used producing excess heat?

Yes

Go to the next step.

Go to Step 6.

VERIFY IF MALFUNCTION IS CAUSED BY OVERHEATING

Warning

• To prevent an accident, work with another person when the vehicle is being driven (one person drives vehicle, other person operates M-MDS).

• Observe legal speed limits when driving the vehicle and perform the procedure in a location where safety can be assured.

• Display PID ECT using the M-MDS.

(See DTC INSPECTION.)

• Is the data monitor item ECT value 110 °C {230 °F} or more while the vehicle is driven on a flat road?

Yes

Explain to the customer that the vehicle is normal.

Go to repair completion verification.

A malfunction due to overheating of the coolant system can be considered.

• Perform malfunction diagnosis according to [COOLING SYSTEM CONCERNS-OVERHEATING ].

(See COOLING SYSTEM CONCERNS-OVERHEATING [SKYACTIV-D].)

INSPECT ECT SENSOR FOR MALFUNCTION

• Inspect the applicable part.

(See ENGINE COOLANT TEMPERATURE (ECT) SENSOR INSPECTION [SKYACTIV-D 1.8].)

• Is the part normal?

Yes

Go to the next step.

Repair or replace the malfunctioning location and perform the repair completion verification.

(See ENGINE COOLANT TEMPERATURE (ECT) SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 1.8].)

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.

― Start the engine and warm it up.

― Drive the vehicle.

• 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 [(E)].)

If the CAN communication is normal, perform the diagnosis from Step 1.
