INTRODUCTION

Infiniti is conducting a Voluntary Service Campaign on certain specific Model Year 2014 Q50 and Q50 Hybrid vehicles to reprogram the Direct Adaptive Steering (DAST). This service will be performed at no cost to the customer for parts or labor.

IDENTIFICATION NUMBER

Infiniti has assigned identification number P4201 to this campaign. This number must appear on all communication and documentation of any nature dealing with this campaign.

DEALER RESPONSIBILITY

Dealers are to correct each vehicle falling within the range of this campaign that enters the service department. This includes vehicles purchased from private parties or presented by transient (tourist) owners and vehicles in a dealer's inventory.

SERVICE PROCEDURE

IMPORTANT: Make sure this campaign (P4201) 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 synchronized (updated) to the current date. 
    • 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, the DAST may be damaged. 

    • Be sure to turn OFF all vehicle electrical loads.

      If a vehicle electrical load remains ON, the 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 the 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 the 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 modules 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.

      INFORMATION:  If you have DTCs related to the Brake or Steering systems that will not erase, do the following:

      1. Turn the ignition OFF.
      2. Disconnect the 12V battery negative cable.
      3. Wait 5 minutes.
      4. Reconnect the negative battery cable.
      5. Restart the Service Procedure from the beginning.

    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 module, 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 module that is being reprogrammed may need to be replaced. Refer to Control Unit Recovery  on the next page.
  20. Wait for both bar graphs to complete.
    G09111154

    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 Module Recovery on the next page.
    • If the progress bar freezes at 90% more than  3 times "on the same DAST control module" but without  Error Code "12-1-1NR", the DAST control module that is currently being reprogrammed will need to be replaced.
    • If the reprogramming does not complete, refer to Control Unit Recovery  on the next page.
    NOTE: If a DAST control module replacement is required:
    • Refer to the appropriate section of the ESM for the procedure to replace and configure a DAST control module.
    • Make sure to perform Read/Write Configuration  : Save the Control module's configuration before replacement, and then write the configuration to the new control module.

    Control Unit Recovery: 

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

OWNER NOTIFICATION LETTER

OWNER LETTER (typical owner letter) 

Dear Infiniti Q50 Owner:

Infiniti is committed to providing the highest levels of product safety, quality and customer satisfaction. With that in mind, we want to bring to your attention important information regarding a voluntary service campaign to update the Direct Adaptive Steering™ (DAS) system on your vehicle.

REASON FOR SERVICE CAMPAIGN 

In certain conditions such as freezing outside temperatures or a drop in battery charge at startup, the current DAS system software calibration may switch the system to a manual steering mode that requires a noticeable increase in steering effort and illuminates one or more error messages on the vehicle information display. To help prevent this from occurring, Infiniti will update the DAS software and recalibrate the system.

WHAT INFINITI WILL DO 

To ensure your continued satisfaction and confidence in your Q50, your authorized Infiniti retailer will perform a DAS system diagnostic check, software update, and recalibration. In certain instances, your Infiniti retailer may need to replace the DAS control units. All services will be performed at no cost to you for parts or labor  . This service should take approximately 2 hours to complete, but your Infiniti retailer may require your vehicle for a longer period of time based upon their work schedule.

WHAT YOU SHOULD DO 

Please contact your Infiniti retailer at your earliest convenience in order to set an appointment to have your vehicle upgraded at no expense to you. Please bring this notice with you to your service appointment. We understand your time is valuable so your retailer will work with you to make the update as convenient as possible.

Thank you for your cooperation and we are indeed sorry for any inconvenience this may cause you.

Should you have any questions, our representatives would be pleased to assist you.
