  Programming Blank ECM (When ECM Is Not Accessible With C-III Plus)  
 

NOTE :

Use this procedure if the vehicle's old/current ECM cannot be accessed with CONSULT-III plus.

IMPORTANT :

Before starting the program procedure, make sure:

^ ASIST on the CONSULT PC has been freshly synchronized (updated).

^ All C-III plus software updates (if any) have been installed.

NOTE :

The CONSULT PC automatically gets applicable ECM programming data during ASIST synchronization.

^ A screen print for Warranty documentation can be done from the CONSULT PC during this process while still connected to the vehicle.

^ If possible, take the vehicle for a 10 minute drive in order to meet the following conditions:

> Engine coolant temperature: 70 - 100°C (158 - 212°F)

> Battery voltage: More than 12.9V (At idle)

> Transmission: Warmed up

NOTE :

After programming is complete, you will be required to perform Throttle Valve Closed Position, Idle Air Volume Learn (IAVL), Accelerator Closed Position, and DTC erase. The above conditions are required for the IAVL to complete.

1. Install the new "Blank" ECM now.

^ Refer to the appropriate Service Manual for ESM replacement information.

2. Determine the software program part number that will be used during the programming operation as follows:

a. Go to your Nissan electronic parts catalog (FAST or equivalent).

NOTE :

FAST sample screens are shown in the next few steps. Other brand electronic catalogs may view and operate differently.

  

b. Enter the VIN of the vehicle being repaired.

^ Always enter the VIN.

c. Select OK.

  

d. Select SEC.

  

e. Scroll down the list and select Sec-No 226, Description ENGINE CONTROL MODULE.

f. Select the down arrow.

g. Select OK.

h. Click twice on the 23701 number.

^ After clicking twice the number should highlight in red. If another P/N is clicked, the first will change to green. Green or Red will make the P/N display in the P/N search in the next step.

  

i. Select the P/No (part number) search button.

  

j. From the screen show in Figure 5a, write down the ECM software P/N listed for ROM-DATA ID, ID NO FOR PROGRAMMING.

^ The first five digits of this number are 23701-xxxxx.

NOTE :

The last five digits are specific to the vehicle you are working on (based on the VIN), and are used to select the correct program in C-III plus later in this procedure.

3. Connect the C-III plus Vehicle Interface (plus VI) to the vehicle.

^ Make sure to use the correct VI for C-III plus (plus VI).

CAUTION :

Make sure the plus VI is securely connected to the DLC. If the plus VI connection is loose during programming, the process will be interrupted and the ECM may be damaged.

4. Connect the AC Adapter to the CONSULT PC.

CAUTION :

Be sure to connect the AC Adapter. If the CONSULT PC battery voltage drops during programming, the process will be interrupted and the ECM may be damaged.

5. Connect a battery charger to the vehicle battery:

^ Set the battery charger at a low charge rate.

NOTE :

The GR-8 (Battery and Electrical Diagnostic Station) set to "Power Supply" mode is recommended.

CAUTION :

Be sure the battery charger is connected securely to the battery. Make sure the battery voltage stays between 12.0V and 15.5V during programming. If the battery voltage goes out of this range during programming, the ECM may be damaged.

6. Turn off all external Bluetooth(R) devices (e.g., cell phones, printers, etc.) within range of the CONSULT PC and the VI.

CAUTION :

Make sure to turn off all external Bluetooth(R) devices. If Bluetooth(R) signal waves are within range of the CONSULT PC and the plus VI during programming, programming may be interrupted and the ECM may be damaged.

7. Turn the ignition ON (engine OFF / Not Ready).

^ The engine must not start or run during the reprogramming procedure.

8. Turn OFF all vehicle electrical loads such as exterior lights, interior lights, HVAC, blower, rear defogger, audio, NAVI, seat heater, steering wheel heater, etc.

IMPORTANT :

Make sure to turn OFF all vehicle electrical loads. Make sure the battery voltage stays between 12.0V and 15.5V during programming. If the battery voltage goes out of this range during programming, the ECM may be damaged.

9. Open / start C-III plus.

  

10. Wait for the plus VI to be recognized.

^ The serial number will display when the plus VI is recognized.

  

11. Select Re/programming, Configuration.

  

12. Use arrows to view and read all precautions.

13. Check the box confirming the precautions have been read.

NOTE :

The box cannot be checked until all precautions in step 12 have been viewed and read.

14. Select Next.

  

15. Select Nissan, Vehicle Name, and then the correct Model Year.

  

16. Select Programming. (Do not select Reprogramming.)

  

17. Select After Replace ECU.

  

18. Type in the VIN, and then select Confirm.

  

19. Select the ECM software P/N that matches the last 5 digits of the P/N written down in step 2j, and then select Next.

  

20. Use arrows to view and read all precautions.

21. Check the box confirming the precautions have been read.

22. Select Next.

  

23. Make sure OK is highlighted green (battery voltage must be between 12.0 and 15.5 Volts).

24. Select Next.

NOTE :

In the next step, the programming process will begin when Start is selected.

CAUTION :

DO NOT stop programming after selecting Start. This may damage the ECM. Allow programming to complete.

  

25. Select Start.

  

26. Wait for both progress bars to complete.

27. When the screen in Figure 18a displays, programming is complete.

NOTE :

If the screen in Figure 18a does not display (programming does not complete), refer to the "If Programming Does Not Complete" information.

28. Disconnect the GR8 / battery charger from the vehicle.

  

29. Select Next.

30. Go to After Programming has Completed.

NOTE :

Additional steps / operations are required before C-III plus will provide the final programming confirmation report. Go to After Programming has Completed.

  

If programming does not complete and the "!?" symbol displays as shown in Figure 19a:

^ Check battery voltage (12.0 - 15.5V).

^ The ignition is ON and the engine is OFF.

^ External Bluetooth(R) devices are OFF.

^ All electrical loads are OFF.

^ Select Retry and follow the on screen instructions.

NOTE :

Retry may not go through on the first attempt. It can be selected more than once.

  

If programming does not complete and the "X" symbol displays as shown in Figure 21a:

^ Do not disconnect the plus VI or shut down C-III plus if reprogramming does not complete.

^ Check battery voltage (12.0 - 15.5V).

^ The CONSULT A/C adapter is plugged in.

^ The ignition is ON and the engine is OFF.

^ The transmission is in Park.

^ All C-III plus / plus VI cables are securely connected.

^ All C-III plus updates are installed.

^ Select Home, and then restart the program procedure from the beginning.
