СИСТЕМА ECD, Diagnostic DTC:P2463

DTC Code DTC Name
P2463 Diesel Particulate Filter Restriction - Soot Accumulation

DESCRIPTION

A012KJ0E03

The DPF catalyst has the ability to reduce particulate matter (PM). The DPF catalyst is a monolithic type catalyst. Alternating passages in the catalyst have either their inlet or outlet blocked. This forces the exhaust gasses to flow through the walls of the passages (see illustration above). Due to the flow of the exhaust gases through micro-cavities in the passage walls, it is called a "wall-flow" type converter.

During driving with PM accumulation exceeding the threshold, when the exhaust temperature exceeds 250°C (482°F) (Ex.: 3rd gear at 65 to 100 km/h [40 to 62 mph]), PM regeneration will be performed and PM accumulation will be reduced.

While PM regeneration, post injection (injector fuel injection during the exhaust stroke) is performed, and exhaust temperature before the DPF catalytic converter increases to approximately 500 to 700°C (932 to 1292°F).

P2463 With warm engine, drive the vehicle with a constant vehicle speed between 65 to 100 km/h (40 to 62 mph) (3rd gear) for 5 minutes.
Tip:

Due to fail-safe operation when other DTCs are stored, PM regeneration may be prohibited.

These DTCs may be stored due to the fact that PM regeneration is prohibited due to the fail-safe operation of other DTCs.

MONITOR DESCRIPTION

In order to detect an abnormality in the DPF catalytic converter, the ECM monitors the differential pressure in front of and behind the DPF catalyst.

When the differential pressure is large, the ECM determines that the DPF has become contaminated and illuminates the MIL.

A012GEUE02
Tip:

  • If a large amount of carbon deposits exists in the electric EGR control valve assembly, the following parts may also have deposits inside: Intake manifold, diesel throttle body assembly, DPF catalyst, other parts related to the exhaust system.

  • If the DPF catalyst has become clogged with PM (Particulate Matter) and the value of "PM Accumulation Ratio" is more than 149% at an engine speed of 4000 rpm, DTC P2463 (Diesel Particulate Filter Restriction - Soot Accumulation) may be present. If the value of "PM Accumulation Ratio" is about 149% or less at an engine speed of 4000 rpm, the catalyst is probably clogged with PM even if DTC P2463 is not present. Check the PM Accumulation Ratio by entering the following menus on the GTS: Powertrain / Engine and ECT / Data List / PM Accumulation Ratio.

CAUTION / NOTICE / HINT

Note:

  • When replacing the ECM, injector assembly and/or DPF catalyst, perform ECM Initialization and Registration.

  • When cleaning the electric EGR control valve assembly or diesel throttle body assembly, use a piece of cloth soaked with cleaning solvent. Spraying solvent directly onto these parts or soaking the parts in solvent may damage the parts.

Tip:

  • When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the GTS. Then after installing a new ECM, perform all of the initialization and registration procedures for the "Learning Values Write" function by following the instructions shown on the GTS display.

  • Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.

  • Before performing the repair, confirm the recent operation conditions with the customer. If the vehicle is driven primarily at low speeds or under light load, the DPF catalytic temperature does not increase, and PM will accumulate.

    Under these conditions, even if the DPF catalytic converter and the engine are operating normally, the DTC might be stored.

    In this case, perform PM regeneration using the GTS, check that the DTC does nor recur, and then return the vehicle to the customer.

    5. Perform the Active Test and then drive the vehicle at a constant engine speed of 2000 rpm or more (3rd gear) at a vehicle speed between 65 to 100 km/h (40 to 62 mph).

      ОСТОРОЖНО

      When performing the confirmation driving pattern, obey all speed limits and traffic laws.

      Tip:

      While the Active Test being performed, the accelerator pedal opening angle should be kept as constant as possible.

    6. Confirm that both Exhaust Temperature B1S1 and Exhaust Temperature B1S2 reach 250°C (482°F) or higher and the DPNR/DPF Status Reju(PM) turns from "Ready" to "Operate".

      Tip:

      • If the exhaust gas temperature does not reach the specified value, drive the vehicle again with a constant engine speed of 2000 rpm or more (3rd gear) and a vehicle speed within 65 to 100 km/h (40 to 62 mph).

      • Perform the Active Test until one of the following conditions is met:

        1. DPNR/DPF Status Reju(PM) displays "Compl".

        2. DPNR/DPF Status Reju(PM) turns from "Operate" to "Ready" even if the cumulative time of "Operate" exceeds 35 minutes.

        3. DPNR/DPF Status Reju(PM) stays "Ready" even if both Exhaust Temperature B1S1 and Exhaust Temperature B1S2 have reached 250°C (482°F) or higher for more than 10 minutes with an engine speed of 2000 rpm or more. (PM regeneration could not operate.)

      Tester Display
      DPNR/DPF Status Reju(PM)

    9. Confirm the DPNR/DPF Status Reju(PM).

      Tip:

      • While performing PM regeneration, the DPNR/DPF Status Reju(PM) displays "Operate".

      • If the PM regeneration is stopped (DPNR/DPF Status Reju(PM) displays "Ready") because the exhaust gas temperature is reduced due to the driving conditions, the PM regeneration is restarted automatically (DPNR/DPF Status Reju(PM) displays "Operate") when the exhaust gas temperature is increased by driving with a high engine speed driving.

      • If the cumulative time of DPNR/DPF Status Reju(PM) at "Operate" exceeds 35 minutes, the active test will be canceled. In this case, the DPNR/DPF Status Reju(PM) turns to "Ready" and the Active Test / Activate the DPF Rejuvenate (PM) will be prohibited for one hour while engine is running. Thus, perform the Active Test again after running the engine for one hour.

      Tester Display
      DPNR/DPF Status Reju(PM)

    9. Confirm the DPNR/DPF Status Reju(PM).

      Tip:

      • While the performing PM regeneration, the DPNR/DPF Status Reju(PM) displays "Operate".

      • If the PM regeneration is stopped (DPNR/DPF Status Reju(PM) displays "Ready") because the exhaust gas temperature is reduced due to the driving conditions, the PM regeneration is restarted automatically (DPNR/DPF Status Reju(PM) displays "Operate") when the exhaust gas temperature is increased by driving with a high engine speed driving.

      • If the cumulative time of DPNR/DPF Status Reju(PM) at "Operate" exceeds 35 minutes, the Active Test will be canceled. In this case, the DPNR/DPF Status Reju(PM) turns to "Ready" and the Active Test / Activate the DPF Rejuvenate (PM) will be prohibited for one hour while engine is running. Thus, perform the Active Test again after running the engine for one hour.

      • PM regeneration is being performed.

      • If "Activate the DPF Rejuvenate (PM)" is not finished completely, the status turns to "Ready".

        For example, if the vehicle idles for more than 3 minutes while the PM regeneration is being performed, the exhaust gas temperature falls to outside of enabling condition and PM regeneration is stopped.

      • If "Activate the DPF Rejuvenate (PM)" is finished completely, the status turns to "Compl".
      Compl PM regeneration is completed (Amount of PM is 0 g)

    10. Read the values of the Data List / Exhaust Temperature B1S2 in the Snapshot Review function.

      Standard
      DPNR/DPF Status Reju(PM) is "Compl" and Exhaust Temperature B1S2 is 500°C (932°F) or higher during PM regeneration.

  21. CHECK ENGINE ASSEMBLY

    1. Check the engine assembly to determine the cause of low compression and other factors that would cause the exhaust gas temperature to rise insufficiently.

      Tip:

      The speed of each cylinder can be measured (compression test) by using the GTS.

      For the compression test, perform Active Test using GTS (Check the Cylinder Compression) and crank the engine for approximately 10 seconds. At this time, the speed of each cylinder is measured. If the speed of one cylinder is higher than the other cylinders, the compression pressure of that cylinder is determined to be lower than the other cylinders.

      1. Warm up the engine.

      2. Turn the ignition switch off.

      3. Connect the GTS to the DLC3.

      4. Turn the ignition switch to ON and turn the GTS on.

      5. Enter the following menus: Powertrain / Engine and ECT / Active Test / Check the Cylinder Compression / Data List / Engine Speed of Cyl #1, Engine Speed of Cyl #2, Engine Speed of Cyl #3, Engine Speed of Cyl #4 and Av Engine Speed of All Cyl.

      6. Push the snapshot button to turn the snapshot function on.

        Tip:

        Using the snapshot function, data can be recorded during the Active Test.

      7. While the engine is not running, press the ON button to Change the Cylinder Compression to ON.

        Tip:

        After performing the above procedure, Check the Cylinder Compression will start. Fuel injection for all cylinders is prohibited and each cylinder engine speed measurement enters standby mode.

      8. Crank the engine for about 10 seconds.

      9. Monitor the engine speed (Engine Speed of Cyl #1 to #4, Av Engine Speed of All Cyl) displayed on the GTS.

        Tip:

        After approximately 10 seconds of engine cranking, the engine speed measurement of each cylinder will change to the actual engine speed.

        Note:

        • Do not crank the engine continuously for 20 seconds or more.

        • If Check the Cylinder Compression needs to be performed after it is turned ON and performed once, press Exit to return to the Active Test menu screen. Then perform Check the Cylinder Compression again.

        • Use a fully-charged battery.

      10. Stop cranking the engine, and then change "Check the Cylinder Compression" to OFF after the engine stops.

        Note:

        If the Active Test is changed to OFF while the engine is being cranked, the engine will start.

      11. Push the snapshot button to turn the snapshot function off.

      12. Select "Stored Data" on the GTS screen, select the recorded data and display the data as a graph.

        Tip:

        If the data is not displayed as a graph, the change of the values cannot be observed.

      13. Check the change in engine speed values.

    5. Perform the Active Test and then drive the vehicle at a constant engine speed of 2000 rpm or more (3rd gear) at a vehicle speed between 65 to 100 km/h (40 to 62 mph).

      ОСТОРОЖНО

      When performing the confirmation driving pattern, obey all speed limits and traffic laws.

      Tip:

      While the Active Test is being performed, the accelerator pedal opening angle should be kept as constant as possible.

    6. Confirm that both Exhaust Temperature B1S1 and Exhaust Temperature B1S2 reach 250°C (482°F) or higher and the DPNR/DPF Status Reju(PM) turns from "Ready" to "Operate".

      Tip:

      • If the exhaust gas temperature does not reach the specified value, drive the vehicle again with a constant engine speed of 2000 rpm or more (3rd gear) and a vehicle speed within 65 to 100 km/h (40 to 62 mph).

      • Perform the Active Test until the DPNR/DPF Status Reju(PM) displays "Compl".

      Tip:

      • Hold the electric EGR control valve assembly to a light and confirm that the valve contacts with the valve seat securely.

      • If light leaks out from the valve, the electric EGR control valve assembly is not fully closed.

      • If the electric EGR control valve assembly cannot close fully, hesitation or poor acceleration almost certainly have occurred while driving the vehicle.

      • Light passes through part A shown in the illustration even if the valve is completely closed, this is not a malfunction.

    6. Remove the diesel throttle body assembly, intake air connector and EGR pipe connector.

    7. Remove the deposits from the parts and clean them.

      Note:

      • When cleaning the electric EGR control valve assembly and the diesel throttle body assembly, use a piece of cloth. Spraying solvent directly onto these parts or soaking the parts in solvent may damage the parts.

      • Extreme care must be taken to prevent the removed deposits from falling into the engine unit during cleaning.

      Tip:

      • Remove the intake manifold from the cylinder head when it has to be cleaned.

      • Do not leave any deposits in the electric EGR control valve assembly when cleaning the valve.
