    DOWNLOAD NEW DATA FROM CONSULT-II INTO THE VEHICLE (REPROGRAM ECM) 

    CAUTION: Perform this operation in four (4) sections. DO NOT SKIP any of these sections. They must be performed in order, 1 through 4.
    • Section 1: Connect a battery charger and CONSULT-II to the vehicle.
    • Section 2: Confirm the vehicle battery voltage and CONSULT-II "Charger Input".
    • Section 3: Perform ECM Reprogramming.
    • Section 4: Perform ECM Reprogram Confirmation.

    12. Section 1: Connect a battery charger and CONSULT-II to the vehicle. 

  12. Confirm the ignition switch is "OFF".
  13. Connect a battery charger to the vehicle battery.
    1. Set the charger at a low charge rate (trickle charge).
      IMPORTANT: Do not perform ECU reprogramming without connecting a battery charger to the vehicle's battery. Permanent ECU damage can occur.

      Connecting a vehicle battery charger will maintain:

      • Proper CONSULT-II power supply during reprogramming-very important if the CONSULT-II battery is low.
      • Vehicle battery voltage level-especially on late model vehicles where the cooling fans come on during reprogramming.

  14. Connect CONSULT-II to the vehicle using the DLC-II cable with black Converter Box (see Fig 10).
    IMPORTANT:
    • Make sure the DLC-II is straight and fully plugged in to the vehicle.
    • Make sure all other DLC-II cable connections shown in Fig 10 are connected properly.
    Fig 10: DLC-II Connections

    CAUTION:
    • Infiniti requires the use of essential tools shown in Figure 10 when performing ECM reprogramming.
    • J44200-10 "Pigtail" should not be removed from the CONSULT-II DDL Port. This "Pigtail" allows use of the stronger "quick disconnect" cable set.
    • If cables are very often changed at the DDL Port (base) of the CONSULT-II unit, cable connector pin damage may result.
    • If there is connector pin damage, ECM reprogramming may fail. Permanent ECU damage can occur.
  15. Turn "ON" the ignition switch (do not start the engine).
    • CONSULT-II will turn "ON" automatically (see Fig 11).
    • Confirm that all electrical loads* (except for the ignition) are "OFF".

      * Headlights, defroster, A/C, Audio (radio), and cellular telephone, etc.

    CAUTION: DO NOT  connect the CONSULT-II AC power supply for Steps 17, 18 and 19.

    17. Section 2: Confirm the vehicle's battery voltage and CONSULT-II "Charger Input" 

  17. Press SUB MODE  (see Fig 11) then:
    1. Press DOWN  4 times
    2. Select BATTERY CHARGE 
    18. Fig 13: Pressing SUB MODE
    G00438919Courtesy of NISSAN MOTOR CO., U.S.A.
  18. Check the CONSULT-II's "Charger Input" reading (see Fig 13).
    NOTE:
    • "Battery Voltage" is the voltage level of CONSULT-II's battery.
    • "Charger Input" is the voltage level of the vehicle's battery. (It must be above 12 volts.).
  19. The "Charger Input" reading MUST  be above 12 volts (see Fig 13).
    • A reading above 12 volts confirms;
      1. The DLC-II is properly connected to the vehicle,
      2. The vehicle battery voltage is sufficient for ECM reprogramming, and
      3. CONSULT-II has a sufficient power supply to perform ECM reprogramming.
    • If the vehicle's battery voltage ("Charger Input") is below 12 volts, one or more of the following may be the cause:
      1. The battery charger you hooked up in section 1 is not charging the battery (poor connection or it is not working).
      2. The DLC-II does not have a good connection to the vehicle (not straight).
      3. The DLC-II cable may have a malfunction (damaged wire or pins).
      4. The CONSULT-II Converter (J44200-50 / black box) is not working correctly (see Fig 10).
      CAUTION:
      • Do not attempt ECU reprogramming if the vehicle's battery voltage is below 12 volts.
      • Permanent ECU damage can occur if the vehicle battery does not maintain the minimum voltage during ECU reprogramming.
      • If "Charger Input" is above 12 volts, power from the vehicle battery will keep CONSULT-II's power supply at the correct level during reprogramming. (see Fig 13).

      NOTE: This process will take from 10 to 20 minutes
      CAUTION: You must leave the vehicle, CONSULT-II, and the DLC-II cable "undisturbed" (don't touch) until reprogramming is complete.
      NOTE: If CONSULT-II gives you an error message "Unmatch of Vehicle Data":
      • You tried to reprogram with an incorrect data file, or
      • You are trying to reprogram with a file that is already in the ECM.
  27. When the Reprogramming is complete, CONSULT-II will "beep", turn the screen backlight back "ON"on and automatically print out a report (see Fig 19).
    • Remember it may take up to 20 minutes.
    • Attach the print-out to the repair order for future reference.
