DTC P2463:00 [MZR-CD 2.2]
id0102f3154200
DTC P2463:00 |
Diesel particulate filter—soot accumulation |
---|---|
DETECTION CONDITION
|
• The PCM calculates the diesel particulate filter soot accumulation based on the exhaust gas pressure sensor signal. If the PCM calculates that the soot accumulation amount is more than 13 g/L {0.8 Ib/ft3}, the PCM determines that the diesel particulate filter soot accumulation excessive.
Diagnostic support note
• The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.
• FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
• The DTC is stored in the PCM memory.
|
POSSIBLE CAUSE
|
• Exhaust gas pressure sensor piping restriction and/or damaged
• Diesel particulate filter restriction and/or damaged
• PCM malfunction
|
Diagnostic procedure
STEP |
INSPECTION |
ACTION |
|
---|---|---|---|
1
|
IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA (MODE 2)
• Perform the Freeze Frame PID Data Access Procedure.
• Is the DTC P2463:00 on FREEZE FRAME DATA (Mode 2)?
|
Yes
|
Go to the next step.
|
No
|
Go to the troubleshooting procedure for DTC on FREEZE FRAME DATA (Mode 2).
(See DTC TABLE [MZR-CD 2.2].)
|
||
2
|
VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED
• Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?
|
Yes
|
Go to the next step.
|
No
|
Record the FREEZE FRAME DATA (Mode 2)/snapshot data on the repair order, then go to the next step.
|
||
3
|
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
• Verify related Service Information availability.
• Is any related Service Information available?
|
Yes
|
Perform repair or diagnosis according to the available Service Information.
• If the vehicle is not repaired, go to the next step.
|
No
|
Go to the next step.
|
||
4
|
INSPECT EXHAUST GAS PRESSURE SENSOR PIPING
• Inspect the exhaust pressure piping for restriction and damaged.
• Is there any malfunction?
|
Yes
|
Repair or replace the malfunctioning part according to the inspection results, then go to Step 7.
|
No
|
Go to the next step.
|
||
5
|
MONITOR DIESEL PARTICULATE FILTER SOOT ACCUMULATION
• Access the PM_ACC, PM_ACC_DSD and PM_GEN PIDs using the M-MDS.
• Is one of the monitored value 17 g/L (1.06 lb/ft3) or more?
|
Yes
|
Replace the catalytic converter, then go to Step 7.
|
No
|
Perform the injection amount correction procedure then perform the manual diesel particulate filter regeneration procedure, then go to the next step.
|
||
6
|
INSPECT FOR RESTRICTION OR CLOGGED IN DIESEL PARTICULATE FILTER
• Start the engine and warm up to normal operation temperature.
• Access the EXHPRESS_DIF PID using the M-MDS at idle.
• Is the EXHPRESS_DIF PID value less than 4.0 kPa {30 mmHg, 1.2 inHg}?
|
Yes
|
Go to the next step.
|
No
|
Visually inspect the diesel particulate filter.
• If there is any malfunction:
• If there is no malfunction:
|
||
7
|
VERIFY DTC TROUBLESHOOTING COMPLETED
• Make sure to reconnect all disconnected connectors.
• Clear the DTC from the PCM memory using the M-MDS.
• Start the engine.
• Perform the DTC Reading Procedure.
• Is the same DTC present?
|
Yes
|
Replace the PCM, then go to the next step.
|
No
|
Go to the next step.
|
||
8
|
VERIFY AFTER REPAIR PROCEDURE
• Perform the “AFTER REPAIR PROCEDURE”.
• Are any DTCs present?
|
Yes
|
Go to the applicable DTC inspection.
(See DTC TABLE [MZR-CD 2.2].)
|
No
|
DTC troubleshooting completed.
