Step	Inspection	Results	Action
1	VERIFY DTC CAUSING FREEZE FRAME DATA • Is DTC P242F:00 causing the freeze frame data?	Yes	Go to the next step.
No	Inspect the DTC causing the freeze frame data. (See DTC TABLE [PCM (SKYACTIV-D 2.2)])
2	RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION Note • Recording can be facilitated using the screen capture function of the PC. • Record the freeze frame data/snap shot data.	—	Go to the next step.
3	INSPECT EXHAUST GAS PRESSURE SENSOR NO.2 CONNECTOR CONDITION • Switch the ignition OFF. • Disconnect the exhaust gas pressure sensor No.2 connector. • Inspect the connector engagement and connection condition, and inspect the terminals for damage, deformation, corrosion, or disconnection. • Is the connector normal?	Yes	Go to the next step.
No	Repair or replace the connector, then go to Step 5.
4	INSPECT EXHAUST GAS PRESSURE SENSOR NO.2-RELATED PIPING • Visually inspect the exhaust gas pressure No.2-related piping for clogging, damage, or less. (See EXHAUST GAS PRESSURE SENSOR INSPECTION [SKYACTIV-D 2.2]) • Is the exhaust gas pressure sensor No.2-related piping normal?	Yes	Replace the catalytic converter, then go to the next step. (See EXHAUST SYSTEM REMOVAL/INSTALLATION [SKYACTIV-D 2.2])
No	Repair or replace the malfunctioning location, then go to the next step.
5	VERIFY THAT REPAIRS HAVE BEEN COMPLETED • Reconnect all disconnected connectors and hoses. • Refer to the [MEMORY CLEARING PROCEDURE] and clear the DTC. (See CLEARING DTC [PCM (SKYACTIV-D 2.2)]) • Start the engine and drive the vehicle under the freeze frame data/snapshot data condition. 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 the DTCs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)]) • Has DTC P242F:00 been recorded?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [SKYACTIV-D 2.2])
No	Go to the next step.
6	VERIFY OTHER DTCs • Has any other DTC or pending code been stored?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [PCM (SKYACTIV-D 2.2)])
No	DTC troubleshooting completed.

VERIFY DTC CAUSING FREEZE FRAME DATA

• Is DTC P242F:00 causing the freeze frame data?

Yes

Go to the next step.

Inspect the DTC causing the freeze frame data.

(See DTC TABLE [PCM (SKYACTIV-D 2.2)])

RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION

Note

• Recording can be facilitated using the screen capture function of the PC.

• Record the freeze frame data/snap shot data.

—

Go to the next step.

INSPECT EXHAUST GAS PRESSURE SENSOR NO.2 CONNECTOR CONDITION

• Switch the ignition OFF.

• Disconnect the exhaust gas pressure sensor No.2 connector.

• Inspect the connector engagement and connection condition, and inspect the terminals for damage, deformation, corrosion, or disconnection.

• Is the connector normal?

Yes

Go to the next step.

Repair or replace the connector, then go to Step 5.

INSPECT EXHAUST GAS PRESSURE SENSOR NO.2-RELATED PIPING

• Visually inspect the exhaust gas pressure No.2-related piping for clogging, damage, or less.

(See EXHAUST GAS PRESSURE SENSOR INSPECTION [SKYACTIV-D 2.2])

• Is the exhaust gas pressure sensor No.2-related piping normal?

Yes

Replace the catalytic converter, then go to the next step.

(See EXHAUST SYSTEM REMOVAL/INSTALLATION [SKYACTIV-D 2.2])

Repair or replace the malfunctioning location, then go to the next step.

VERIFY THAT REPAIRS HAVE BEEN COMPLETED

• Reconnect all disconnected connectors and hoses.

• Refer to the [MEMORY CLEARING PROCEDURE] and clear the DTC.

(See CLEARING DTC [PCM (SKYACTIV-D 2.2)])

• Start the engine and drive the vehicle under the freeze frame data/snapshot data condition.

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 the DTCs using the M-MDS.

(See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)])
