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
Before starting, make sure your ASIST has been synchronized to the current date and all CONSULT-III plus
(C-III plus) upgrades have been installed.
Parts of the Procedure
PART 1: Confirm Proper Diagnosis and Repair with TECH LINE to Obtain Display Control Unit Order Approval,
Then Place The Order With DENSO
PART 2: Record Multi AV Configuration Values of Original Display Control Unit; Replace Display Control Unit
PART 3: Configure the Multi AV System
PART 4: Manually Configure the Multi AV System (if needed)
PART 5: Register the Replacement Display Control Unit
PART 6: 2014 model year vehicles only: Check the software version – confirm it is the newest version – update
if needed
PART 1:
Confirm Proper Diagnosis and Repair With TECH LINE to Obtain Display Control Unit Order Approval,
Then Place the Order With DENSO.
To improve customer satisfaction by providing the correct repair on the first visit, Infiniti has put in place a
procedure for ordering an “exchange” or “new” DCU.


To ensure a proper diagnosis and repair, the technician will need to call TECH LINE to confirm (or assist
with) their diagnosis and the proper repair prior to ordering the DCU.



DENSO will require a confirmation from TECH LINE prior to shipping an exchange DCU.



New DCUs will be put on parts restriction and will need to be cleared prior to the order shipping. In the
event that a new DCU is required, the warranty claims call center will verify that TECH LINE has
recommended replacement.



This process applies to vehicles equipped with a Navigation system as well as non-Navigation vehicles.



TECH LINE has the support of engineering and DENSO in diagnosis, if needed.



Most DCUs ordered should be an exchange unit versus a new unit.

The requirement of calling TECH LINE for confirmation to replace a DCU will be monitored to ensure the most
effective and accurate method of repair. Future changes or adjustments may be made to this process to
increase repair timeliness and/or customer satisfaction.
A new DCU is required only if:


The vehicle has not yet been sold.




The customer requests a new DCU on a non-warranty repair.
The exchange DCU is not available.



Insurance claim replacement.

NOTE: Infiniti also recommends using this procedure for non-warranty repairs to ensure that proper diagnosis
and repair is performed.

Contact TECH LINE to Confirm DCU Replacement is Needed
NOTE: Contacting TECH LINE is done to confirm diagnosis. An exchange DCU must be ordered by your
parts department directly from DENSO. See Order an Exchange DCU Form DENSO below.
1. Duplicate and verify the customer’s concern if possible. If duplication is not possible, gather as much
information about the issue as possible from the service advisor/writer or customer.
2. Check for any connected devices (phone, iPod, MP3 player, etc.) or determine if a connected device is
present during the concern. Gather model and software version information if possible.
3. Call TECH LINE, after gathering preliminary information of the concern. After a diagnosis of the concern
has been performed, and the technician and TECH LINE agree that the DCU should be replaced, go to
step 4.
4. Provide the following information to TECH LINE:
DCU part number _______________________________________
NOTE: The DCU part number can be found on the label on the back of the DCU, or
with CONSULT-III plus by going to Diagnosis (One System) > MULTI AV > ECU
Identification.
Is the vehicle equipped with a Navigation System? _____________
Dealer name and fax number ______________________________
Dealer contact name _____________________________________
5. TECH LINE will confirm with DENSO, by email, that the diagnosis has occurred and a DCU replacement is
approved.
NOTE: TECH LINE does not send an email or fax to your parts department.
Order an Exchange DCU From DENSO
6. After steps 1 – 5 above have been completed, your parts department will order the replacement
exchange DCU as follows:
a. Fill out the Exchange Order Form and fax or email it to DENSO.
