AND 12 VOLT BATTERY REPLACEMENT
CAMPAIGN ID #:
P5323
APPLIED VEHICLES: 2014 – 2015 Q50 Hybrid (V37)
Check Service COMM to confirm campaign eligibility.
 There are five bulletins with different service campaign ID numbers for the DAST system.
 Each bulletin is applicable to specific vehicles.
 Make sure the correct bulletin (Campaign ID #) is being used.
INTRODUCTION
Infiniti is conducting a Voluntary Service Campaign on certain specific Model Year 2014 - 2015 Q50 Hybrid cold
state vehicles (listed below) to reprogram the Direct Adaptive Steering (DAST) and replace the 12 volt battery.
This service will be performed at no cost to the customer for parts or labor.
Colorado, Connecticut, Idaho, Illinois, Indiana, Iowa, Kansas, Maine, Massachusetts, Michigan, Minnesota,
Montana, Nebraska, Nevada, New Hampshire, New York, North Dakota, Ohio, Pennsylvania, South
Dakota, Utah, Vermont, Washington, Wisconsin, Wyoming.
IDENTIFICATION NUMBER
Infiniti has assigned identification number P5323 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.
Infiniti Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are properly trained
individuals who have the equipment, tools, safety instruction, and know-how to do a job properly and safely. NOTE: If you believe that
a described condition may apply to a particular vehicle, DO NOT assume that it does. See your Infiniti dealer to determine if this
applies to your vehicle.

SERVICE PROCEDURE
IMPORTANT: Make sure this campaign P5323 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.

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.
Figure 15
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.

be reused.
5. Reset the customer preferred settings for the Automatic Air Conditioning System.
 If needed, refer to System Settings in the HAC section of the ESM.
6. Reinitialize and check the Anti-Pinch Function for all Auto-UP power windows:
7. Reinitialize “Automatic Drive Positioner” (ADP).
8. Inform the customer that:
 Some memory settings in the navigation system may need to be reset.
 Settings for ADP seat and mirror may need to be reset.
Reinitialize Anti-Pinch:
a. Turn the ignition ON.
b. Operate the power window switch to fully open the window (glass all the way down).
c. Hold the window switch UP until the glass stops at the fully closed position, and then continue holding
the switch UP for 2 seconds or more.
d. Check that AUTO-UP function operates normally.
Check Anti-Pinch Function:
a.
b.
c.
d.
Fully open the door window (glass all the way down).
Hold a piece of wood near the fully closed position.
Close the door window glass using the AUTO-UP switch. Allow the window glass to hit the wood.
Check the following conditions:
 Check that the glass lowers for approximately 150 mm (5.9 in), without pinching the wood, and
stops.
 Check that the glass does not rise when operating the power window main switch, while the widow
is lowering after hitting the wood.
CAUTION: Do not check anti-pinch function with hands or other body parts because they may be pinched.
Reinitialize ADP:
a. Turn ignition switch from ACC to OFF position.
b. Open → Close → Open Driver door.
