  Programming Blank ECM (When ECM Is Accessible With C-III Plus)  
 

NOTE :

^ Do not replace/install the new ECM until told to do so in the Service Procedure.

^ Use this procedure if the vehicle's old/current ECM can 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. 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.

2. 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.

3. 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.

4. 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.

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

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

6. 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.

7. Open / start C-III plus.

^ You will be accessing the old/current ECM.

  

8. Wait for the plus VI to be recognized.

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

  

9. Select Re/programming, Configuration.

  

10. Use arrows (if needed) to view and read all precautions.

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

12. Select Next.

  

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

^ If the screen in Figure 4 does not display, skip to step 14.

  

14. Make sure VIN or Chassis # matches the vehicle's VIN.

15. If the correct VIN is displayed, select Confirm.

  

16. Select Confirm.

  

17. Select ENGINE.

  

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

  

19. Select Before Replace ECU.

  

20. Select Save.

  

21. Select Next.

  

22. Make sure the VIN in the Saved Data List (Figure 12) matches the vehicle's VIN.

^ If the VIN is not correct, select Delete and then start over from the C-III plus Home screen.

23. If the VIN is correct, select Confirm.

^ This step will save the vehicle's existing ECM information.

  

24. After Confirm is selected in step 23, the screen in Figure 13 will display.

25. Replace the ECM now:

^ Leave C-III plus turned ON (it should continue to display the screen in Figure 13 while replacing the ECM).

^ Make sure the CONSULT PC A/C power supply is connected.

^ Turn the ignition OFF.

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

26. After the ECM has been replaced (Blank ECM is now installed).

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

^ The engine must not start during the programming procedure.

b. Make sure the GR8 / battery charger is connected.

  

27. Select Programming.

  

28. Select After Replace ECU.

29. Use arrows to view and read all precautions.

  

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

31. Select Next.

  

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

33. Select Next.

NOTE :

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

CAUTION :

DO NOT stop programming after selecting Start, doing so may damage the ECM. Allow programming to complete.

  

34. Select Start.

  

35. Wait for both progress bars to complete.

36. When the screen in Figure 20 displays, programming is complete.

NOTE :

If the screen in Figure 20 does not display (programming does not complete), refer to the "If Programming Does Not Complete" information.

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

  

38. Select Next.

39. 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 21:

^ 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 22:

^ 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.
