DTC P117A:00 [PCM (SKYACTIV-D)]

• This DTC is detected as a record indicating that the torque restriction control for piston protection has been performed.

• The torque restriction control for piston protection prevents engine burn by decreasing the fuel injection amount.

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 CONDITION FOR MALFUNCTION • Verify how the customer drives the vehicle by asking the customer the following: ― Continue the high engine speed condition with the message related to a diesel particulate filter malfunction in the display. ― Continue the high engine speed condition with the diesel particulate filter indicator light illuminated. ― Vehicle is driven continuously at low engine speed and high load. • Are any of the conditions above applicable to the vehicle use conditions?	Yes	Explain to the customer that the vehicle is normal. (malfunction caused by driving at high engine speed with engine oil diluted) If there is a concern with customer’s driving, provide the customer some pertinent advice (such as gear selection, how to use manual mode). Go to repair completion verification.
No	Go to the next step.
5	INSPECT ENGINE OIL LEAKAGE • Start the engine. • Visually inspect the engine oil runner for engine oil leakage. • Is there any leakage?	Yes	Repair or replace the malfunctioning part according to the inspection results, then add genuine motor oil. Perform the “ENGINE OIL DATA RESET”, then go to repair completion verification. (See ENGINE OIL DATA RESET [SKYACTIV-D 1.8].)
No	Go to the next step.
6	INSPECT ENGINE OIL PRESSURE SENSOR FOR MALFUNCTION • Inspect the applicable part. (See ENGINE OIL PRESSURE 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 OIL TEMPERATURE SENSOR/ENGINE OIL PRESSURE 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 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 [(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 CONDITION FOR MALFUNCTION

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

― Continue the high engine speed condition with the message related to a diesel particulate filter malfunction in the display.

― Continue the high engine speed condition with the diesel particulate filter indicator light illuminated.

― Vehicle is driven continuously at low engine speed and high load.

• Are any of the conditions above applicable to the vehicle use conditions?

Yes

Explain to the customer that the vehicle is normal. (malfunction caused by driving at high engine speed with engine oil diluted)

If there is a concern with customer’s driving, provide the customer some pertinent advice (such as gear selection, how to use manual mode).
