ECD SYSTEM(w/ Glow Plug Controller) PRECAUTION


  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.

    Tech Tips

    When the ECM and other component(s) are replaced at the same time, perform the following utility items by following the instructions shown on the GTS display, starting with the ECM.

    • 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

    B004491C01
    *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

    Depending on the combination of output DTCs and the status of the engine oil change reminder light*1 or engine oil change reminder message*2*3 displayed and illumination condition of the MIL, the necessary procedures to be performed will vary.

  4. DPF WARNING LIGHT (MESSAGE)


    1. If the DPF warning light*1 or DPF warning message*2 does not turn off a few seconds after the ignition switch is turned to ON, or if the DPF warning light turns on*1 or a DPF warning message is displayed*2 at any other time, perform the following procedure.

      Note

      If DTC P252F is stored, troubleshoot for it first.

      1. Drive the vehicle for 20 to 30 minutes at 65 km/h (40 mph) or more until the DPF warning light*1 or DPF warning message*2 turns off.

        CAUTION:

        When performing a drive test, obey all speed limits and traffic laws.

      2. If the DPF warning light*1 or DPF warning message*2 does not turn off after 35 minutes or more, perform the 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 the DTCs, immediately perform the Active Test and drive the vehicle.

        (e) According to the display on the GTS, perform the Active Test and drive the vehicle at a constant speed between 65 and 100 km/h (40 and 62 mph) while maintaining a constant engine speed of 2000 rpm or more (3rd gear). [E]

        Note

        When performing a drive test, obey all speed limits and traffic laws.

        Tech Tips

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

        (f) Check that the values both Exhaust Temperature B1S1 and Exhaust Temperature B1S2 are 220°C (428°F) or higher and the value of DPNR/DPF Status Reju(PM) has changed from "Ready" to "Operate". [F]

        Tech Tips


        • If the exhaust gas temperature does not reach the specified value, continue driving the vehicle at a constant speed between 65 and 100 km/h (40 and 62 mph) while maintaining an engine speed of 2000 rpm or more (3rd gear).

        • Perform the Active Test until the value of DPNR/DPF Status Reju(PM) changes to "Compl".

        (g) Confirm that the DPF warning light*1 or DPF warning message*2 has turned off.

        Tech Tips


        • If the DPF warning light*1 or DPF warning message*2 does not turn off, repeat the procedure [steps A to F].

        • If the DPF warning light*1 or DPF warning message*2 does not turn off even after repeating the procedure, replace the No. 2 exhaust manifold (catalytic converter).
