Download New Data From Consult-II Into the Vehicle
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.
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.
A. Set the charger at a low charge rate (trickle charge).
IMPORTANT
14. Connect CONSULT-II to the vehicle using the DLC-II cable with black Converter Box (see Figure 10 above).
VERY 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 Figure 10 are connected properly.
CAUTION
^ Nissan 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 Figure 11).
^ Confirm that all electrical loads* (except for the ignition) are "OFF".
* Headlights, defroster, A/C, Audio (radio), and cellular telephone, etc.
16. Roll down the driver's window part way, exit the vehicle, close the door, and hang the CONSULT II unit on the outside of the window (see Figure 12).
^ This step is necessary to ensure the CONSULT-II and DLC-II cable will not be disturbed during reprogramming.
CAUTION:
DO NOT connect the CONSULT-II AC power supply for Steps 17, 18 and 19.
Section 2: Confirm the vehicle's battery voltage and CONSULT-II "Charger Input"
17. Press [SUB MODE] (see Figure 11) then:
A. Press [DOWN] 4 times.
B. Select [BATTERY CHARGE].
18. Check the CONSULT-II's "Charger Input" reading (see Figure 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 Figure 13 shown above).
^ A reading above 12 volts confirms;
a. The DLC-II is properly connected to the vehicle,
b. The vehicle battery voltage is sufficient for ECM reprogramming, and
c. CONSULT-II has a sufficient power supply to perform ECM reprogramming.
^ If the vehicles battery voltage ("Charger Input") is below 12 volts, one or more of the following may be the cause:
a. The battery charger you hooked up in section 1 is not charging the battery (poor connection or it is not working).
b. The DLC-II does not have a good connection to the vehicle (not straight).
c. The DLC-II cable may have a malfunction (damaged wire or pins).
d. The CONSULT-II Converter (J44200-50 / black box) is not working correctly (see Figure 10).
CAUTION
Section 3: ECM Reprogramming
20. Press [INITIATE ECU REPROGRAM] (see Figure 14), then
A. Press [ECM]
B. Review the precaution.
C. Press [NEXT]
21. Press [CHECK ECM P/N] to "confirm" (take note of) the current ECM part number (see Figure 15).
NOTE:
This is the vehicle's ECM part number BEFORE Reprogramming.
22. Press [COPY] to print the current ECM part number for future reference.
23. Press [BACK] to return to the main menu.
24. Select the ECM program to install (see Figure 16).
25. The "REPROGRAM START" window should appear (see Figure 17).
NOTE:
If you get an error message, refer to the ECU Reprogramming Software Operations Manual.
CAUTION DURING REPROGRAMMING:
^ Do not unplug CONSULT-II from the vehicle during reprogramming. Permanent ECM damage can occur.
^ Do not open any door or the trunk during reprogramming.
^ On some vehicles, the cooling fans may come on during reprogramming. This is a normal condition. Do not disconnect the cooling fans. Forgetting to reconnect them may cause severe engine damage. A vehicle battery charger is needed* to maintain the battery voltage level during reprogramming.
* You should have hooked up a battery charger in Section 1.
26. Press [START].
^ After a few seconds, the window shown in Figure 18 will appear.
^ CONSULT-II will now turn "OFF" its screen backlight.
^ When the screen backlight goes "OFF", ECM reprogramming has started.
NOTE:
This process will take from 10 to 20 minutes.
CAUTION:
You must leave the vehicle and the CONSULT-II unit "undisturbed" (don't touch) until reprogramming is complete.
NOTE:
If CONSULT-II screen 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 and automatically print out a report (see Figure 19).
^ Remember it may take up to 20 minutes.
^ Attach the print-out to the repair order for future reference.
CAUTION
If CONSULT-II prints "REPROGRAMMING UNEXPECTEDLY TERMINATED":
^ The ECM has been permanently damaged and will require replacement.
^ In this case, perform steps A through G under "REPROGRAMMING UNEXPECTEDLY TERMINATED".
Do not start the engine with the damaged ECM installed.
The above chart is provided as a reference to confirm the correct final ECM P/N after reprogramming.
NOTE:
^ Part numbers for ECM programs are subject to change.
^ If a more recent part number is available for any of the ECM data (specified in the Chart above) the latest version should be used to complete this campaign repair.
^ ASIST contains the latest version of all ECM data.
28. Press [END] to return to the main menu.
29. Turn the ignition switch "OFF" and CONSULT-II "OFF".
30. Make sure the throttle is released; then operate the ignition as shown above.
The above ignition cycle will:
^ Reset ECM self learned Data.
^ Complete the Accelerator Pedal Released Position Learning.
^ Complete the Throttle Valve Closed Position Learning.
Section 4: Perform ECM Reprogram Confirmation.
31. Remove the reprogramming CARD from CONSULT-II and insert the Diagnostic Card (red/white card).
32. Start the engine.
33. Make sure all DTCs are cleared (erased).
^ If necessary, erase any DTC's that may have stored during the reprogramming procedure.
34. Idle Air Volume Learning Procedure:
^ For Sentra: Perform the Idle Air Volume Leaning Procedure.
^ For Frontier: Idle Air Volume Leaning Procedure is not needed.
35. Check Target idle speed shown above.
