6	VERIFY DTCs • Refer to the [MEMORY CLEARING PROCEDURE] and clear the DTC. (See CLEARING DTC.) • 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 DTC INSPECTION.) • Has DTC P2458:00 been recorded?	Yes	Diesel particulate filter clogging in the catalytic converter (diesel particulate filter), damage, or loss can be considered. • Replace the catalytic converter (diesel particulate filter), then go to the next step. (See EXHAUST SYSTEM REMOVAL/INSTALLATION [SKYACTIV-D 1.8].)
No	Go to repair completion verification 2.
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 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. • 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.
