*a Exhaust Gas - -

The exhaust fuel addition injector assembly is mounted on the outlet of the turbocharger sub-assembly, and low pressure fuel is supplied to the exhaust fuel addition injector assembly by the feed pump in the supply pump assembly. The exhaust fuel addition injector assembly adds fuel in response to a control signal from the ECM, in order to perform PM forced regeneration.

During PM forced regeneration, the exhaust fuel addition injector assembly adds fuel to raise the DPF* catalyst temperature.

Tip:

  • Due to fail-safe operation when other DTCs (that involve the engine power limit) are stored, PM forced regeneration may be prohibited.

    This DTC or P20CF, P244B, P244C and P2463 may be stored due to the fact that PM forced regeneration is prohibited due to the fail-safe operation of other DTCs.

  • The air fuel ratio and the exhaust gas temperature can be checked by entering the following menus on the GTS: Powertrain / Engine and ECT / Data List / All Data / AF Lambda B1S1, Exhaust Temperature B1S1, Exhaust Temperature B1S2 and Exhaust Temperature B1S3.

  • Malfunctions in the engine itself may affect the DPF system control and cause storage of this DTC. For example, malfunctions in the injector assemblies that cause a large amount of smoke emission: These affect the exhaust fuel addition injector assembly operation. Blockages or leaks in the air intake system, or an EGR system malfunction such as EGR passage blockages: These malfunctions affect the DPF catalyst temperature control. Therefore, the engine condition itself should also be checked, in addition to the exhaust fuel addition injector assembly.

Tip:

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.

PROCEDURE

  1. READ DTC OUTPUT (RECORD STORED DTC AND FREEZE FRAME DATA (PROCEDURE 1))

    1. Connect the GTS to the DLC3.

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

    3. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

    4. Record the stored DTC and freeze frame data.

  2. REPLACE EXHAUST GAS TEMPERATURE SENSOR

    1. Check the values of "Exhaust Temperature B1S1", "Exhaust Temperature B1S2" and "Exhaust Temperature B1S3" that were saved in Procedure 1.

      Table 2. Result
      Result Items to be Replaced
      DTC P2428 is output and the value of "Exhaust Temperature B1S1" is 850°C (1562°F) or higher Exhaust gas temperature sensor (B1S1)
      DTC P200E is output and the value of "Exhaust Temperature B1S2" is 850°C (1562°F) or higher No. 2 exhaust gas temperature sensor (B1S2)
      DTC P200C is output and the value of "Exhaust Temperature B1S3" is 850°C (1562°F) or higher No. 3 exhaust gas temperature sensor (B1S3)

    2. If DTC P200C, P200E and/or P2428 is output, the exhaust gas temperature sensors need to be replaced. However, make sure to perform all diagnostic procedures for P200C, P200E and/or P2428 before replacing the exhaust gas temperature sensors.

      Tip:

      If the exhaust gas temperature sensors are subjected to an abnormally high temperature, the internal resistance of the sensor increases. This causes incorrect temperature measurement.

    2. Stop the vehicle and allow the engine to idle.

    3. Fully depress the accelerator pedal for 5 seconds, and then release it [A].

    4. Repeat the procedure [A] 10 times [B].

    5. Check for black smoke emission during the procedure [A] and [B].

      OK

  4. REPLACE EXHAUST MANIFOLD CONVERTER SUB-ASSEMBLY

    1. Even though it has been determined that the DPF catalytic converter (Exhaust manifold converter sub-assembly) needs to be replaced, make sure to perform all diagnostic procedures for DTC P200C, P200E and/or P2428 before replacing it.

      Tip:

      This DTC is stored because an excessive amount of PM has accumulated and resulted in abnormal combustion. It is necessary to diagnose the cause of abnormal PM accumulation and repair the problem. Therefore, do not perform replacement at this time.

  9. CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED

    1. Clear the DTC and Exhaust Fuel Addition FB value by disconnecting the cable from the negative (-) battery terminal or removing the EFI-MAIN fuse for 1 minute or more.

      Tip:

      • The accumulated PM volume stored in the ECM cannot be initialized using the GTS.

      • To perform PM forced regeneration, it is necessary to perform initialization of the accumulated PM volume stored in the ECM.

    2. Connect the GTS to the DLC3.

    3. Start the engine and drive the vehicle until the engine coolant temperature reaches 60°C (140°F) or higher.

    4. Move the shift lever to neutral and set the parking brake.

    5. Turn the GTS on.

    6. Enter the following menus: Powertrain / Engine and ECT / Active Test / Activate the DPF Rejuvenate (PM) / All Data / PM Accumulation Ratio.

      Powertrain > Engine and ECT > Active Test
      Active Test Display
      Activate the DPF Rejuvenate (PM)
      Data List Display
      PM Accumulation Ratio

    7. Perform the Active Test while the vehicle is driven at a constant vehicle speed within 50 to 100 km/h (31 to 62 mph) (transaxle in 3rd gear) for more than 15 minutes.

      ОСТОРОЖНО

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

      Tip:

      • While the "Activate the DPF Rejuvenate (PM)" Active Test is being performed, the accelerator opening angle should be kept as constant as possible.

      • When you start driving, "DPNR/DPF Status Reju(PM)" on the Data List displays "Compl". However, continue to drive the vehicle until "PM Accumulation Ratio" drops to 0%.

      • Once "PM Accumulation Ratio" drops to 0%, regeneration is complete.

    8. Continue to drive the vehicle until "PM Accumulation Ratio" drops to 0%.

      ОСТОРОЖНО

      Be aware of excessive heat on and around the exhaust pipes during PM forced regeneration.

      Note:

      If PM forced regeneration stops, repair the malfunction that caused it to stop, and perform it again to complete the operation.

      Tip:

      • PM forced regeneration completes in 15 to 40 minutes.

      • PM forced regeneration time changes depending on PM Accumulation Ratio and driving conditions.

      • A fail-safe stops PM forced regeneration if Catalyst Differential Press increases too much during regeneration.

      • Exhaust Temperature B1S3 becomes 500°C (932°F) or higher within 20 minutes of PM forced regeneration start.

      • PM forced regeneration will be stopped if the accelerator pedal is depressed during regeneration. In this case, PM forced regeneration needs to be performed again.

      • Even if PM forced regeneration stops while it is occurring, the GTS displays Compl (complete) for DPNR/DPF Status Reju(PM).
