DTC P2458:00 [PCM (SKYACTIV-D 2.2)]

id0102j5154100

DTC P2458:00	diesel particulate filter system: Excess diesel particulate filter accumulation (mid)
DETECTION CONDITION	•  Amount of accumulated soot exceeds 10 g/l due to diesel particulate filter clogging. Diagnostic support note •  This is a continuous monitor (CCM). •  The check engine light does not illuminate. •  FREEZE FRAME DATA/Snapshot data is available. •  DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION	•  Limits engine torque. •  Inhibits the automatic diesel particulate filter regeneration control.
POSSIBLE CAUSE	•  Pipe clogging or damage between exhaust sensor No.2 and catalytic converter •  diesel particulate filter clogging or damage •  PCM malfunction
SYSTEM WIRING DIAGRAM	Not applicable

Diagnostic Procedure

Step	Inspection	Results	Action
1	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.
2	VERIFY OTHER RELATED DTCs •  Switch the ignition OFF, and then switch it ON (engine off). •  Display the DTCs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)].) •  Has DTC P242F:00 been recorded?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [PCM (SKYACTIV-D 2.2)].)
		No	Go to the next step.
3	VERIFY OTHER RELATED DTCs •  Switch the ignition OFF, and then switch it ON (engine off). •  Display the DTCs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)].) •  Has any DTC other than P2458:00 or P2463:00 been stored?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [PCM (SKYACTIV-D 2.2)].) Note •  When a DTC other than DTC P2458:00 or P2463:00 is stored, compulsory diesel particulate filter regeneration may be restricted by the PCM control. Perform applicable DTC troubleshooting, and then perform compulsory diesel particulate filter regeneration.
		No	Go to the next step.
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	Perform fuel injection amount learning and implement compulsory diesel particulate filter regeneration. (See FUEL INJECTOR INJECTION AMOUNT CORRECTION [SKYACTIV-D 2.2].) (See DIESEL PARTICULATE FILTER DATA RESET [SKYACTIV-D 2.2].) Go to the next step. Go to the next step.
		No	Repair or replace the malfunctioning location, then go to Step 6.
5	VERIFY DTCs •  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 P2458:00 been recorded?	Yes	diesel particulate filter clogging in the catalytic converter, damage, or loss can be considered. •  Replace the catalytic converter, then go to the next step. (See EXHAUST SYSTEM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
		No	Go to Step 7.
6	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 (mode 2)/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 P2458:00 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.
7	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	Referring to each adjustment procedure, perform fuel injection amount learning and the diesel particulate filter data reset. (See FUEL INJECTOR INJECTION AMOUNT CORRECTION [SKYACTIV-D 2.2].) (See DIESEL PARTICULATE FILTER DATA RESET [SKYACTIV-D 2.2].) DTC troubleshooting completed.
