Procedure C - Perform QR25 ECM Reprogramming

Procedure C - Perform QR25 ECM Reprogramming:

For 2003 and 2004 Applied Vehicles: When you perform Procedure C (ECM Reprogramming), go to NTB06-051a for reprogramming information. You will still need to perform all other parts of this bulletin on 2003 and 2004 Applied Vehicles.

Procedure C should be performed by an OBDII Certified technician.

Important Information About ECM Reprogramming and The Special "QR25 Campaign ECM Software" Reprogramming Card:

^ This is a special ECM Reprogramming procedure just for this Campaign.

^ Your dealership has been supplied with a special "QR25 Campaign ECM Software" reprogramming card for this campaign.

^ This card already contains all the ECM data needed for this campaign.

^ ECM data files do NOT have to be down-loaded from ASIST.

^ If the special 'QR25 Campaign ECM Software" reprogramming card is inoperable, refer to the Inoperable "QR25 Campaign ECM Software" Reprogramming Card Procedure.

1. With the Diagnostics (red/white) card still in slot A of CONSULT-II.





2. Connect CONSULT-II to the vehicle making sure the connector is fully plugged in.

3. Turn the ignition switch "ON", but do not start the engine. CONSULT-II will turn on automatically

4. Press "SUB MODE", then select "BATTERY CHARGE".





5. Check the vehicle's battery voltage reading on the CONSULT-II screen (see Figure C2).

NOTE:

^ The vehicle's battery voltage is called "CHARGER INPUT".

^ This is to confirm CONSULT-II is receiving voltage from the vehicle battery.

6. Turn the vehicle's ignition switch "OFF" and CONSULT-II "OFF".





7. Remove the Diagnostics Card (red/white) and install the "QR25 Campaign ECM Software" reprogramming card (Orange 16MB) into slot A of CONSULT-II (see Figure C3).





8. Connect a battery charger (or a "known good" additional 12V battery) to the vehicle battery (see Figure C4).

^ You MUST Trickle charge the battery during the reprogramming procedure.

^ This is to make sure the battery voltage does not drop below 12.0 volts.

^ DO NOT boost charge the battery during reprogramming.

^ It is normal for the radiator fans to come on during this reprogramming procedure.

^ DO NOT DISCONNECT ANY ELECTRICAL CONNECTIONS TO THE RADIATOR FANS.

CAUTION:
Do not allow the vehicles battery voltage to drop below 12.0 volts during ECU Reprogramming. Permanent ECU damage can occur if the battery does not maintain the minimum voltage during the ECU Reprogramming.





9. Make Sure the DLC-II cable is firmly plugged into the vehicle harness (see CAUTION below step 8). Turn the ignition switch "ON", but do not start the engine. CONSULT-II will turn on automatically (see Figure C5).

10. Confirm that all electrical loads (except for the ignition) such as headlights, defroster, A/C, Audio (radio), cellular telephone (if applicable) are "OFF".

CAUTION:
Do not unplug CONSULT-II from the vehicle while Reprogramming ECM. Do not attempt ECM reprogramming with any vehicle electrical loads "ON" except for the ignition. Permanent ECM damage can occur.





11. Roll the driver's window part way down, exit the vehicle, close the door and hang the CONSULT-II unit on the outside of the window (see Figure C6)

CAUTION:
Do not open the vehicle doors or trunk during the reprogramming.





12. Press "INITIATE ECU REPROGRAM" (see Figure C7), then do the following:

^ Press "ECM"

^ Review the precaution

^ Press "NEXT"





13. Press "CHECK ECM P/N" to confirm (take note of) the ECM part number on the vehicle to be reprogrammed (see Figure C8).

NOTE:
Shown below is the vehicle's ECM part number BEFORE Reprogramming.

14. Press "COPY" to print the current ECM part number for future reference.

15. Press "BACK" to return to the main menu.





16. Refer to the chart. Match the vehicles Current ECM Part Number with the New ECM Part Number. Make a note of the "number match" (current and new ECM P/N) on the repair order.

NOTE:
B15 = Sentra, L31 = Altima





17. Now go to the CONSULT-II screen and select the correct ECM program to install from the choices on the screen (see Figure C9). Refer to the new ECM P/N note in the "number match" note you made in step 16.





18. The "REPROGRAM START" window should appear (see Figure C10).

NOTE:
If you get an "error" message, refer to the ECU Reprogramming Software Operations Manual in ASIST for instructions.





19. Press "START". After a moment the window shown in Figure C11 will come up. CONSULT-II will now turn OFF its screen "backlight" and begin to reprogram the ECM.

NOTE:
This process will take about 20 minutes.

CAUTION:
Leave the vehicle and the CONSULT-II unit "undisturbed" (don't "touch" them) until Reprogramming is complete.

When the Reprogramming is complete, CONSULT-II will:

^ "Beep"

^ Turn the screen backlight ON

^ Automatically print out a report

CAUTION:

^ If CONSULT-II prints out an ERROR message during the reprogramming process, the ECM has been permanently damaged and you'll have to replace it.

^ If this happens, it is possible that a step(s) in the reprogramming procedure was missed/performed incorrectly, the vehicle's voltage supply (to CONSULT-II) was too low (below 12V), or the CONSULT-II unit may have a problem.

^ Perform steps A through E below.

A. Turn the ignition key "OFF", turn CONSULT-II "OFF" and DISCONNECT THE NEGATIVE TERMINAL OF THE VEHICLE BATTERY (Do not start the vehicle with the damaged ECM installed).

B. Remove the damaged ECM from the vehicle.

C. Attach the CONSULT-II printout to the repair order for future reference.

D. Replace the damaged ECM.

NOTE:
The replacement ECM that you order may have to be re-programmed to the latest part number for the vehicle you are working on.

E. Return to the beginning of Procedure C, step 1. Carefully follow each step exactly as written.





20. Once ECM Reprogramming is done, CONSULT-II will print out a report (see Figure C12). Attach this to the repair order for future reference.

21. Press "END" to return to the main menu. Enter the vehicle and turn the ignition switch OFF and CONSULT-II OFF. Disconnect CONSULT-II from the vehicle.

22. Wait more than 10 seconds, then turn the ignition switch "ON" for 1 second. Then, turn the ignition switch "OFF" again for 10 seconds.





23 Repeat step 16 for a total of three times (see Figure C13). This will reset the ECM "self learned" values.

24. Start the engine and confirm it is operating normally.

25. Return to the Repair Flow Chart for further instructions.

Inoperable "QR25 Campaign ECM Software" Reprogramming Card Procedure

If the special "QR25 Campaign ECM Software" reprogramming card is not working, you can do the following:

A. Update the special "QR25 Campaign ECM Software" reprogramming card using ASIST. This will require ASIST version 8.0.0 or greater.

CAUTION:
ECM files will be lost if the special "QR25 Campaign ECM Software" reprogramming card is updated on ASIST versions earlier than Version 8.0.0.

NOTE:
Use the keypad in the ECU Reprogramming Data Window, to enter code 03070 to update the card. This will download all ECM data required for this campaign.

B. Use your existing CONSULT-II Reprogramming Card (8MB) to download the individual ECM data (from ASIST) required to complete the campaign repair.

NOTE:
Use the conventional Model/Model Year search method to download the data.
