Diagnostic Procedure

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-G (US))].)
No
Go to the next step.
4
INSPECT VEHICLE CONDITION FOR EFFECT ON MALFUNCTION
• Verify how the customer drives the vehicle by asking the customer the following:
― Engine speed is high and remains high for continuous long periods like when climbing a long steep grade.
• Is the engine generating excessive heat when driven?
Yes
Go to the next step.
No
Go to Step 6.
5
DETERMINE IF MALFUNCTION CAUSE IS OVERHEATING OR OTHER
Warning
• While performing this step, always operate the vehicle in a safe and lawful manner.
• 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.
• Access the ECT PID using the M-MDS. (See PID/DATA MONITOR INSPECTION.)
• Is the ECT PID value less than 122 °C {252 °F} while the vehicle is driven on a flat road?
Yes
Explain to the customer that the vehicle is normal.
Go to repair completion verification 2.
No
The cause of this concern could be from the cooling system overheating.
• Perform the symptom troubleshooting “COOLING SYSTEM CONCERNS-OVERHEATING”. (See COOLING SYSTEM CONCERNS-OVERHEATING [SKYACTIV-G (US)].)
6
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 1.
(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.
― Start the engine and warm it up completely.
― 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 [(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.
