Nissan 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 Nissan 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 Service 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 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, Nissan
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 nonNavigation 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: Nissan 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 on the next page.
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

DCU replacement is approved.
NOTE: TECH LINE does not send an email or fax to your parts department.

6. After steps 1-5 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.
Order forms are found on nnanet.com:
a. Log onto NNAnet.com.
b. Confirm Brand View is Nissan.
c. Select Workspace.
