СИСТЕМА ECD (для моделей без контроллера свечей накаливания) МЕРЫ ПРЕДОСТОРОЖНОСТИ


  1. INITIALIZATION AND REGISTRATION

    Note


    • When the ECM and/or the other component(s) mentioned below are replaced, perform the following utility items on the GTS, referring to the corresponding Initialization and Registration procedure.

    • If the ECM is replaced, register the ECU communication ID for Engine Immobiliser System (w/o entry and stat system) (Refer to the Service Bulletin for Registration).

    • When the cable is disconnected from the negative (-) battery terminal, initialize the following system(s) after the cable is reconnected.

    • DPF Deterioration Record is the ash accumulation volume in the DPF catalytic converter calculated by the ECM. If the ash accumulation volume in the DPF catalytic converter increases, the difference in pressure in front of and behind the DPF catalytic converter will increase. The difference in pressure in front of and behind the DPF catalytic converter is offset depending on the volume of accumulated ash.

    Tech Tips


    • Before replacing the ECM, perform the "Learning Values Save" function using the GTS. Then after installing the new ECM, perform all initialization and registration procedures for the "Learning Values Write" function by following the instructions shown on the GTS display.

    • After replacing any of the injector assemblies, perform both the "Injector Compensation" and the "Pilot Quantity Learning Values Reset" functions using the GTS.

    • After replacing the engine assembly, perform both the "Injector Compensation" and the "Pilot Quantity Learning Values Reset" functions using the GTS.

  2. INJECTOR COMPENSATION CODE

    A01T8DKC01
    *a Example
    *b Injector Compensation Code

    Tech Tips

    Each injector assembly has different fuel injection characteristics. In order to optimize the fuel injections, the ECM uses injector compensation codes to balance the different characteristics of each injector assembly. Injector compensation codes are 12-digit, alphanumeric values printed on the head of each injector.

    Note

    If an incorrect injector compensation code is input into the ECM, the engine assembly may rattle or engine idling may become rough. In addition, engine failure may occur and the life of the engine may be shortened.

  3. ENGINE OIL CHANGE REMINDER LIGHT (MESSAGE) AND MIL

    Tech Tips

    The troubleshooting procedure varies depending on the combination of the output DTCs and indicator light (message) status (engine oil change reminder light*1 or engine oil change reminder message*2 and MIL). Therefore perform troubleshooting referring to the table below.

    *1: w/ multi-information display (segment LCD type).

    *2: w/ multi-information display (dot LCD type).


    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. Read the output DTCs and check if P252F and P2463 are output simultaneously.

      No. Engine Oil Change Reminder Light (Message) Status MIL Status Note Proceed to

  4. DPF WARNING LIGHT


    1. If the DPF warning light does not turn off a few seconds after the ignition switch is turned on, or if the DPF warning light turns on at any other time, perform the following procedure.

      Note

      If DTC P252F is stored, troubleshoot the DTC first.

      Click here


      1. Drive the vehicle for 20 to 30 minutes at 65 km/h (40 mph) or more until the DPF warning light turns off.

        CAUTION:

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

      2. If the DPF warning light does not turn off for 40 minutes or more, perform following procedure.

        (a) Connect the GTS to the DLC3. [A]

        (b) Start the engine and turn the GTS on. [B]

        (c) Clear the DTCs. [C]

        (d) Enter the following menus: Powertrain / Engine and ECT / Active Test / Activate the DPF Rejuvenate (PM) / Data List / Exhaust Temperature B1S1, Exhaust Temperature B1S2, DPNR/DPF Status Reju(PM). [D]

        Tech Tips

        After clearing DTCs, immediately perform the Active Test, and then drive the vehicle.

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

        Note

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

        Tech Tips

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

        (f) 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". [F]

        Tech Tips


        • 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 between 65 to 100 km/h (40 to 62 mph).

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

        (g)Confirm the DPF warning light has turned off.

        Tech Tips


        • If the DPF warning light does not turn off, repeat the procedure [steps A to F].

        • If the DPF warning light does not turn off even after repeating the procedure, replace the No. 2 exhaust manifold converter sub-assembly (DPF catalytic converter).

  5. FOR USING GTS

    CAUTION:


    • Read the instruction manuals before using the GTS.

    • Prevent the GTS cable from being caught on the pedals, shift lever and steering wheel when driving with the GTS connected to the vehicle.

    • When driving the vehicle for testing purposes and using the GTS, two persons are required. One for driving the vehicle, and the other for operating the GTS.
