INTRODUCTION

Infiniti is conducting a Voluntary Safety Recall Campaign on certain specific Model Year 2014 Q50 sedan and hybrid vehicles to reprogram the Direct Adaptive Steering System (DAST). Only 38 vehicles are subject to this campaign. Affected dealers have already been contacted. 

IDENTIFICATION NUMBER

Infiniti has assigned identification number R1310 to this campaign. This number must appear on all communication and documentation of any nature dealing with this campaign.

DEALER RESPONSIBILITY

It is the dealer's responsibility to check Service Comm for the campaign status on each vehicle falling within the range of this voluntary safety recall which for any reason enters the service department. This includes vehicles purchased from private parties or presented by transient (tourist) owners and vehicles in a dealer's inventory. Federal law requires that new vehicles in dealer inventory which are the subject of a safety recall must be corrected prior to sale. Failure to do so can result in civil penalties by the National Highway Traffic Safety Administration.  While federal law applies only to new vehicles, Infiniti strongly encourages dealers to correct any used vehicles in their inventory before they are retailed.

SERVICE PROCEDURE

IMPORTANT: Make sure this campaign applies to the vehicle you are working on by using the VIN and checking Service COMM.
  1. Before continuing, it is IMPORTANT to make sure: 
    • ASIST on the CONSULT PC has been freshly synchronized (updated). 
    • All CONSULT related software updates (if any) have been installed. 
      NOTE: The CONSULT PC automatically gets all reprogramming software during ASIST synchronization.
    CAUTION:
    • Connect the GR8 to the vehicle 12 volt battery and set to ECM power supply mode. If the vehicle battery voltage drops below 12.0V or rises above 13.5V  during reprogramming, DAST may be damaged. 
    • Be sure to turn OFF all vehicle electrical loads.

      If a vehicle electrical load remains ON, DAST may be damaged  .

    • Be sure to connect the AC Adapter.

      If the CONSULT PC battery voltage drops during reprogramming, the process will be interrupted and DAST 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 DAST may be damaged  .
  2. Once all ASIST and CONSULT related updates have been performed, attach the CONSULT PC to the vehicle.
    • Connect the plus VI to the CONSULT PC with the USB cable  .
    • Connect the AC adapter to the CONSULT PC.
    IMPORTANT: Reprogramming Procedure must be performed 3 separate times  to reprogram the control units for DAST 1, DAST 2, and EPS/DAST 3.
  3. Turn ON the CONSULT PC, and then open CONSULT III plus (C-III plus).
    NOTE: Make sure all applications other than C-III plus are closed.
  4. Press the ignition switch twice without  depressing the brake pedal.
    • The meter and gauges will illuminate.
      CAUTION: Do Not  start the engine, the DAST may be damaged. (For Hybrid vehicles, make sure the Ready light is OFF.)
      NOTE: Make sure ALL  accessories are turned OFF.
  5. Erase all stored DTCs as follows:
    1. Wait for the plus VI to be recognized.
    2. Select Diagnosis (All Systems)  and Confirm  .
    3. Wait for system call to complete.
    4. Erase all DTCs.
  6. Go to Re/programming, Configuration. 
    1. Select the Home  button and then YES  to return to the screen shown in Figure 1.

    G09125730
  12. Use the page arrows to scroll and select the correct control unit  to be reprogrammed.

    Make sure to reprogram the control units in this order:

    DAST 1,  then DAST 2,  and then EPS/DAST 3 

    NOTE: DAST 1 and DAST 2 are shown in Figure 6; EPS/DAST 3 is not shown.
    G09125731
  13. Wait for System Call to complete and then select Reprogramming. 
    G09125732
  14. When you get to the screen shown in Figure 8, confirm reprogramming applies as follows:
    1. Find the DAST Part Number  and write it on the repair order.
      NOTE: This is the current  DAST Part Number. DAST 1 is shown; DAST 2 and DAST 3 are similar.
      G09125733
    2. Compare the P/N you wrote down to the numbers in the Current Part Number  column of Table A  below:
      • If there is a match  , that reprogramming applies  . Continue with the reprogramming procedure.
      • If there is not a match  , this campaign does not apply  or it has already been done.
        NOTE: If there is no match for DAST 1, there will be no match for DAST 2 or DAST 3. You can stop. This bulletin does not apply.

      NOTE: For reprogramming to continue, vehicle 12V battery voltage must stay within 12 volts and 13.5 volts. .
      G09125739
    IMPORTANT: Until the reprogramming has completed:
    • Do not disconnect the USB cable, although the following message appears:

      "Disconnecting CONSULT and VI is Available"

    • Do not touch the Home button until instructed to. 
    • When the VI is transferring the reprogram to the DAST control unit, do not disconnect the VI from the vehicle even if the PC freezes.
    • If you need to disconnect the VI, first check the LED on the VI body to confirm that the communication from the VI to the vehicle has completed and the LED for the vehicle icon is OFF.
    • If you accidentally disconnect the VI during program writing to the vehicle, the DAST control unit that is being reprogrammed will need to be replaced. 
  20. Wait for both bar graphs to complete.
    G09125740

    Possible errors that may rarely occur: 

    • If the progress bar freezes at 90% of a complete transfer to the VI and error code "12-1-1NR" is displayed (see Figure 16 on the next page), turn the ignition OFF, then ON,  and then refer to Control Unit Recovery on the next page.
    • If the progress bar freezes at 90% more than  3 times "on the same DAST control unit" but without  Error Code "12-1-1NR", the DAST control unit that is currently being reprogrammed will need to be replaced.
      NOTE: If a DAST control unit replacement is required:
      • Refer to the appropriate section of the ESM for the procedure to replace and configure a DAST control unit.
      • Make sure to perform Read/Write Configuration  and save the Control unit's configuration before replacement, and then write the configuration to the new control unit.

    Control Unit Recovery: 

    Do not disconnect plus VI or shut down Consult III plus if reprogramming does not complete. 

    If reprogramming does not complete and the "!?" icon displays as shown in Figure 16: 

    • Check battery voltage (12.0-13.5 V).
