CONSULT-III ECM REPROGRAMMING PROCEDURE
APPLIED VEHICLES:
All CONSULT-III (C-III) compatible Infiniti vehicles
SERVICE INFORMATION
A complete step-by-step General Procedure for C-III ECM Reprogramming is now available in the on-line version of this bulletin.
This General Procedure is also available via hyperlink from specific C-III symptom-based Technical Service Bulletins in ASIST.
CAUTION: BEFORE STARTING REPROGRAMMING
^ Connect a battery charger to the vehicle battery. If the 12V battery voltage drops during reprogramming, the ECM may be damaged.
^ Be sure to turn OFF all vehicle electrical loads. If a vehicle electrical load remains ON, the ECM may be damaged.
^ For ECM reprogramming, the C-III MUST be connected to the VI using the USB cable. Be sure to connect the AC Adapter. If the C-III battery
voltage drops during reprogramming, the process will be interrupted and the ECM will be damaged.
General Procedure
Updated March 25, 2009
CONSULT-III (C-III) ECM REPROGRAMMING
A symptom based TSB is required before this procedure.
IMPORTANT: Before starting, make sure:
^ ASIST on the C-III computer has been freshly synchronized (updated).
^ All C-III software updates (if any) have been installed.
NOTE:
The C-III computer automatically gets applicable ECM reprogramming data during ASIST synchronization.
381
^ C-III PCMCIA Card Adapter is installed.
^ C-III Security Card is installed.
^ A symptom based TSB is required before using this procedure.
^ A screen print for Warranty documentation can be done from C-III during this process while still cable-connected to the vehicle.
1. Use the USB cable to connect the Vehicle Interface (VI) to the C-III computer and then connect the VI to the vehicle.
CAUTION
2. Connect the AC Adapter to the C-III computer.
CAUTION
3. Connect a battery charger to the vehicle battery:
For Conventional Vehicles
^ 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.
382
CAUTION
For Hybrid Vehicles
^ Use the GR-8 Battery and Electrical Diagnostic Station.
^ If needed, refer to Hybrid Service TSBs for connecting the GR-8 to the Hybrid 12V battery.
CAUTION
4. Turn the ignition ON with the engine OFF.
^ The engine must be OFF (not running) during the reprogramming procedure. For Hybrid vehicles, Make sure the dash warning lights are ON and
the "READY" light is OFF.
^ Turn OFF all vehicle electrical loads such as exterior lights, interior lights, HVAC, blower, rear defogger, audio, NAVI, seat heater, steering
wheel heater, etc.
CAUTION
5. Make sure the engine cooling fan(s) are not running.
If the cooling fans are running:
a. Turn the ignition OFF.
b. Wait for the engine to cool.
c. Turn the ignition ON (with engine OFF).
d. Make sure the engine cooling fans are not running.
6. Open / start ASIST on the C-III computer.
7. Select CONSULT Utilities, CONSULT-III, and Wait for the "Detecting VI/MI in progress" message to clear.
383
8. Select the detected VI from the list. (See Figure 1.)
9. Select Connect. (See Figure 1.)
10. Wait for the "Checking the firmware version" message to clear.
11. Select ECM reprogramming / Programming (see Figure 2).
12. Select Select.
384
13. Select Confirm.
14. Select Diagnosis.
15. Wait for ECM Diagnosis to complete.
385
16. If there are no DTCs, select the "Repair" icon (see Figure 5).
^ If there are any DTCs other than those listed in the accompanying Symptom based TSB, diagnose, perform repairs, and erase DTCs before
continuing.
17. Select the "ECM Reprogram" icon. (See Figure 6.)
386
18. At this point, refer to the symptom based TSB that directed you to reprogram the ECM.
The symptom based TSB is required, in order to determine which reprogramming part number to use.
19. Select Next
NOTE:
If the screen in Figure 8 appears, there is data stored in the VI. Select "Yes" to proceed with Reprogramming.
387
20. The screen in Figure 9 is displayed during data transfer.
CAUTION:
During data transfer:
^ DO NOT disturb the VI, DDL, or USB connections.
^ DO NOT try to start the engine or turn the ignition OFF.
^ The engine fans may turn on. This is normal.
NOTE:
^ If "Transfer To VI" reaches 100%, and "Transfer To ECU" does not start, or
^ The Error in Figure 9A displays.
a. DO NOT replace the ECM. The ECM is not damaged.
b. Check / make sure the battery voltage is above 12 V and all vehicle electrical loads are turned OFF (see step 3 and 4).
c. Select Cancel Data Transmission, then click on the "Home" icon (upper left corner of C-III screen) and re-start from the beginning (step 1).
388
21. When the screen in Figure 10 appears, ECM reprogramming is complete.
NOTE:
If you can't print the above screen:
a. Select the Print icon.
b. Select Save.
c. Select OK.
A copy of the screen is now saved in the Toughbook(R) PC.

In the ApplicationData screen/folder select Print Images folder.
When the file was saved it was automatically given a file name using the current date and time.
Select and print the file/screen image that you want.
NOTE:
During reprogramming DTCs will set in several systems. DTCs must be erased from all systems.
Erase DTCs from all systems
22. Click on the "Home" icon (top left corner of the C-III screen).
