DTC P2463:00 [PCM (SKYACTIV-D)]


 id0102t5154200


Outline

System malfunction location

Diesel particulate filter: Excess diesel particulate filter accumulation (large)

Detection condition
•  Amount of accumulated soot exceeds 13 g/l because of diesel particulate filter clogging.
Fail-safe
•  PCM restricts engine torque.
•  Inhibits the auto diesel particulate filter regeneration control.
•  Inhibits the DENOx/DESOx control.
•  Inhibits the EGR control.
Possible cause
•  Pipe clogging or damage between exhaust gas pressure sensor No.2 and catalytic converter (diesel particulate filter)
•  Diesel particulate filter clogging or damage
•  PCM malfunction
System wiring diagram

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 EXHAUST GAS PRESSURE SENSOR No.2 RELATED PIPING
•  Inspect exhaust gas pressure sensor No.2-related piping for clogging, damage, and loss.
•  Is the exhaust gas pressure sensor No.2 piping normal?
Yes
Perform fuel injection amount learning and implement compulsory diesel particulate filter regeneration.
Go to the next step.
Note
•  If any of the following DTCs are stored, compulsory diesel particulate filter regeneration cannot be implemented due to the PCM control.
•  Perform applicable DTC troubleshooting then perform compulsory diesel particulate filter regeneration.
•  DTC P0093:00, P0102:00, P0103:00, P0107:00, P0108:00, P0112:00, P0113:00, P0117:00, P0118:00, P0201:00, P0202:00, P0203:00, P0204:00, P0313:00, P0337:00, P0406:00, P0500:00, P0545:00, P0546:00, P0605:00, P0606:00, P115A:00, P1378:00, P1379:00, P2032:00, P2033:00, P2146:00, P2147:00, P2148:00, P2149:00, P2150:00, P2151:00, P2228:00, P2229:00, P242C:00, P242D:00, P242F:00*, P2454:00, P2455:00, P2463:00*, P253F:00
*When a high quantity of soot has accumulated in the diesel particulate filter and the PCM has stored DTC P242F:00 or P2463:00, compulsory diesel particulate filter regeneration cannot be implemented.
No
Repair or replace the malfunctioning location, then go to repair completion verification.

VERIFY DTCs
•  Install/connect the part removed/disconnected during the troubleshooting procedure.
•  Clear the DTC recorded in the memory.
•  Replicate the vehicle conditions at the time the DTC was detected using the following procedure.
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.
•  Is the same Pending DTC present?
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.
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.
•  Replicate the vehicle conditions at the time the DTC was detected using the following procedure.
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.
―  Start the engine and drive the vehicle under the freeze frame data/snapshot data condition.
•  Perform the DTC inspection for the PCM.
•  Is the same Pending DTC present?
Yes
Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.
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.
No
Go to the next step.
Repair completion verification 2
VERIFY IF OTHER DTCs DISPLAYED
•  Perform the DTC inspection.
•  Are any other DTCs displayed?
Yes
Repair the malfunctioning location according to the applicable DTC troubleshooting.
No
DTC troubleshooting completed.
