Voluntary Service Campaign 2011 QX56 Vehicle Dynamic Control (VDC) Reprogramming (ITB11-031A)

Reprogram ABS Control Unit

1. Connect the CONSULT PC to the vehicle to begin the reprogramming procedure.
   CAUTION:

   • Connect a battery charger to the vehicle battery. If the 12V battery voltage drops during reprogramming, the ABS Control Unit may be damaged  .
   • Be sure to turn OFF all vehicle electrical loads. If a vehicle electrical load remains ON, the ABS Control Unit may be damaged  .
   • For ABS Control Unit reprogramming, the CONSULT PC MUST be connected to the VI using the USB cable.
   • Be sure to connect the AC Adapter. If the CONSULT PC battery voltage drops during reprogramming, the process will be interrupted and the ABS Control Unit may be damaged  .
   • Turn off all external Bluetooth® devices (e.g., cell phones, printers, etc.) within range of the CONSULT PC and the VI. If Bluetooth® signal waves are within range of the CONSULT PC during reprogramming, reprogramming may be interrupted and the ABS Control Unit may be damaged  .
   IMPORTANT: Before starting, make sure:
   

   • ASIST on the CONSULT PC has been freshly synchronized (updated). 
   • All C-III software updates (if any) have been installed. 
   NOTE: The CONSULT PC automatically gets reprogramming data during ASIST synchronization.
   • C-III PCMCIA Card Adapter is installed.
   • C-III Security Card is installed.
   • 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 CONSULT PC and then connect the VI to the vehicle.
   CAUTION: For ABS Control Unit reprogramming, be sure to have the CONSULT PC connected to the VI with the USB cable. If the CONSULT PC is not connected to the VI with the USB cable, the ABS Control Unit 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 reprogramming recovery, the process will be interrupted and the ABS Control Unit will 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 above 12 V during reprogramming. If the battery voltage drops during reprogramming, the ABS Control Unit may be damaged  .
4. Turn the ignition ON with the engine OFF.
   • The engine must be OFF (not running) during the reprogramming procedure.
   • 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. If the vehicle battery voltage drops below 12 V before reprogramming starts, reprogramming will not complete. After the "Transfer To VI" is complete, the reprogramming will stop, and "Transfer To ECU" will not start.
5. Make sure the engine cooling fan(s) are not running.

   If the cooling fans are running:

   1. Turn the ignition OFF.
   2. Wait for the engine to cool.
   3. Turn the ignition ON (with engine OFF).
   4. Make sure the engine cooling fans are not running.
6. Open/start ASIST on the CONSULT PC.
7. Select CONSULT Utilities, CONSULT-III, and Wait for the "Detecting VI/MI in progress" message to clear.
8. Select the detected VI from the list (see Fig 1).
9. Select Connect (see Fig 1).
10. Wait for the "Checking the firmware version" message to clear (picture not shown).
11. Select QX56  and 2011  model year from the lists (see Fig 1 for example).

12. Select  Select (see Fig 1).
13. After verifying the information in the Vehicle Selection: Confirmation Vehicle  screen is correct, select Confirm  .
14. Wait for the System Call progress bar to reach 100%.
    • Your C-III screen will look similar to Fig 1.
15. Select Repair  .
16. Select the "ECM Reprogram"  icon.
17. When you get to the reprogramming screen shown in Fig 1, confirm this bulletin applies as follows.
    1. Write down the ABS Control Unit  part number on the Repair Order.
       NOTE:

       • Control unit part numbers for other vehicle systems may be listed. Part numbers for other systems do not apply to this bulletin.
       • If an ABS Control Unit part number is not listed, this campaign does not apply or it has already been completed.  Close C-III, turn off and disconnect the CONSULT PC and VI from the vehicle, and then recheck Service Comm for campaign eligibility.
       • If this column is blank  (no part number listed), this campaign does not apply or it has already been completed.  Close C-III, turn off and disconnect the CONSULT PC and VI from the vehicle, and then recheck Service Comm for campaign eligibility.
    2. Compare the Part Number you wrote down to the number in the Current ABS Control Unit Part Number  column in TABLE A .
       • If there is a match,  this campaign applies  . Continue with the reprogramming procedure.
       • If there is not a match,  this campaign does not apply  or it has already been done. Close C-III, turn off and disconnect the CONSULT PC and VI from the vehicle, and then recheck Service Comm for campaign eligibility.
