Appendix B: Complete ECM Reprogramming Instructions
APPENDIX B: COMPLETE ECM REPROGRAMMING INSTRUCTIONSBefore beginning reprogramming, use CONSULT-II to make sure there are no DTCs stored in the ECM.
Repairs for stored DTCs must be done before performing the ECM reprogramming. Use ASIST for DTC diagnostic and repair information.
Repairs for stored DTCs are not related to this campaign.
[Reprogramming should be performed by an OBD-II Certified technician.]
Check the Current ECM Part Number (P/N)
1. With the Diagnostic Card (Red/white card) in CONSULT-II and CONSULT-II turned "ON", print the ECM Part Number as follows:
[START(Nissan)] >> [ENGINE] >> [ECM PART NUMBER] >> [COPY]
2. Attach this printout to the Repair Order.
^ Figure A1 is an example of the ECM Part Number printout.
3. Compare your vehicle's ECM P/N to those shown under Current ECM P/N in Chart A, shown above.
A. If your vehicle's ECM P/N matches one of the Current ECM P/N's in the chart above:
^ Go to Reprogramming the ECM below.
B. If your vehicle's ECM P/N does not match one of the Current ECM P/N's in the chart above:
^ This campaign may not apply or has already been done on this vehicle.
^ Recheck Service Comm (campaign ID PB023) to confirm the vehicle you're working on is affected by this campaign.
Reprogramming the ECM
[Reprogramming should be performed by an OBD-II Certified technician.]
The reprogramming procedure involves three general steps:
Setting up
1. Install the Reprogramming Card into CONSULT-II.
^ Make sure CONSULT-II is disconnected from the vehicle and turned OFF.
^ The Reprogramming Software Card is the "orange" Card.
^ Use slot Atop slot (see Figure A2).
2. Connect the AC power supply to CONSULT-II.
3. Connect CONSULT-II to the ASIST PC with the special Ethernet cable (P/N 02002554 is printed on the cable).
A. Connect one end to CONSULT-II at the "PC port".
B. Connect the other end to the ASIST PC at the "Ethernet card" connection port.
4. Confirm the CONSULT-II date and time are correctly set as follows:
(This is necessary to provide a valid print-out for warranty claims.)
A. With the Reprogramming card in slot A, turn ON CONSULT-II.
B. Touch [SUB MODE].
C. Touch [SET DATE] (see Figure A3).
1) If the date is not correct, touch the [MONTH], [DAY] or [YEAR] as needed. Then adjust it by using arrow keys. Once done, press [SAVE], press [BACK], and go to step D.
2) If the date is OK, press [BACK] and go to step D.
D. Touch [SET TIME] (see Figure A3).
1) If the time is not correct, touch the [HOUR], [MINUTE] and [AM/PM] Adjust by using arrow keys. Once done, press [SAVE], press [BACK] and go to Step 5.
2) If time is OK, press [BACK] and go to step 5.
IMPORTANT NOTE:
^ If your ASIST PC is already being used to perform ECM Reprogramming, proceed to step 5 below.
^ If you are unsure whether your ASIST PC has already been set up for ECM Reprogramming, look in ASIST, under "CONSULT Utilities" - "CONSULT-II Info" - "NISSAN" - "ECU Reprogramming". This will give you instructions for setting the Ethernet (IP) Address of the ASIST PC and CONSULT-II. You will need to do this before performing ECM reprogramming.

^ 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 A11).
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 A11 are connected properly.
CAUTION
15. Turn ON the ignition switch (do not start the engine).
^ CONSULT-II will turn ON automatically (see Figure A12).
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 A13).
^ 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 A14) then:
A. Press [DOWN] 4 times.
B. Select [BATTERY CHARGE].
18. Check the CONSULT-II's "Charger Input" reading (see Figure A14).
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 A14).
^ 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

CAUTION:
You must leave the vehicle and the CONSULT-II unit "undisturbed" (don't touch) until reprogramming is complete.
NOTE:
If the 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 A20).
^ 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 F (under "Programming Unexpectedly Terminated" below.
Do not start the engine with the damaged ECM installed.
The chart above 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.
