DTC P24A4:00 [PCM (SKYACTIV-X)]


 id0102u9058700

Note
•  To determine the malfunctioning part, proceed with the diagnostics from “Function Inspection Using M-MDS”.

Details On DTCs

Description

Gasoline particulate filter: Excess gasoline particulate filter accumulation (exceeding permissible amount)

Detection condition
Determination conditions
•  Soot accumulation amount (estimated value) in gasoline particulate filter is 15.2 g {0.536 oz} or more.
Preconditions
•  Not applicable
Drive cycle
•  1
Self test type
•  CMDTC self test
Sensor used
•  GPF pressure sensor
Fail-safe function
•  Inhibits the fuel cut control.
Vehicle status when DTCs are output
•  A message related to the gasoline particulate filter is indicated on the display.
Possible cause
•  Excess soot accumulation in gasoline particulate filter
•  Catalytic converter (gasoline particulate filter) clogging or damage
•  PCM malfunction


Function Explanation (DTC Detection Outline)

•  If more than the permissible amount of soot accumulates in the gasoline particulate filter, the PCM inhibits automatic gasoline particulate filter regeneration control.
•  If the soot accumulation amount (estimated value) in the gasoline particulate filter is 15.2 g {0.536 oz} or more, the PCM determines a gasoline particulate filter malfunction and stores a DTC.
Note
•  If DTC P24A4:00 is stored, replace the catalytic converter (gasoline particulate filter).

Repeatability Verification Procedure

1.  Not applicable
Note
•  The PCM determines to store DTC P24A4:00 based on the estimated value. Therefore, the malfunction symptom cannot be repeated for a period of time after repair completion verification has been performed correctly.

Results

Action

1
PURPOSE: 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.
2
PURPOSE: 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 Troubleshooting Diagnostic Procedure to perform the procedure from Step 1.


Troubleshooting Diagnostic Procedure

Intention of troubleshooting procedure
•  Step 1
―  Repair the catalytic converter (gasoline particulate filter).
•  Repair completion verification
―  Verify that the primary malfunction is resolved and there are no other malfunctions.

Action

1
PURPOSE: REPAIR THE CATALYTIC CONVERTER (GASOLINE PARTICULATE FILTER)
•  Clogging or damage of the catalytic converter (gasoline particulate filter) can be considered. Replace the catalytic converter (gasoline particulate filter).
•  Perform the gasoline particulate filter data reset and perform the repair completion verification 1.
—
Go to the next step.
Repair completion verification 1
PURPOSE: 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.
―  Implement the repeatability verification procedure.
•  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
PURPOSE: 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.
