DISPLAY CONTROL UNIT SERVICE INFORMATION
APPLIED VEHICLES: 2018-2019 Armada (Y62)
2018-2019 Pathfinder (R52)
SERVICE INFORMATION
If the Display Control Unit (DCU) needs to be replaced on an APPLIED VEHICLE for any
reason, follow the steps in the SERVICE PROCEDURE to:

Confirm proper diagnosis and repair with TECH LINE to obtain DCU order approval.

Place the order with DENSO.

Configure the Multi AV system.
NOTE:
 The original DCU must be installed in the vehicle while performing part of this
procedure. DO NOT remove the original DCU until instructed.
 The DCU order approval process does not apply to 2017 Pathfinder vehicles.
TECH LINE authorization is not needed for 2017 Pathfinder vehicles. For 2017
Pathfinder vehicles, refer to NTB16-104.
 This process does not apply to 2017 Armada vehicles since it uses a different
system.
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) updates have been installed.
Parts of the Procedure
PART 1: Confirm Proper Diagnosis and Repair with TECH LINE to Obtain DCU Order
Approval / Place Order with DENSO
PART 2: Record Multi AV Configuration Values of Original DCU / Replace DCU
PART 3: Configure Multi AV System
PART 4: Manually Configure Multi AV System (if needed)
PART 1: Confirm Proper Diagnosis and Repair with TECH LINE to Obtain DCU Order
Approval / Place Order with DENSO
NOTE: The DCU order approval process is to be performed on all 2018-2019 APPLIED
VEHICLES and does not apply to 2017 and earlier models. TECH LINE authorization is not
needed for 2017 and earlier models.
To improve customer satisfaction by providing the correct repair on the first visit, Nissan has
established a procedure for ordering an “exchange” or “new” DCU.

To ensure proper diagnosis and repair, the technician will need to contact 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.

Approval from TECH LINE does not mean the DCU has been ordered. The DCU can be
ordered from DENSO only after approval from TECH LINE.

New DCUs will be put on parts restriction and will need to be cleared before the order is
shipped. 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 contacting TECH LINE for confirmation to replace a DCU will be monitored
to ensure the most effective and accurate method of repair.
2/14
NTB19-002
NOTE: In most cases, an exchange DCU will be ordered. 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.

It is an insurance claim replacement.
NOTE: While not required, Nissan 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. After diagnosis, an exchange
DCU can be ordered by your parts department directly from DENSO. See Order an Exchange
DCU from 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. Contact TECH LINE after gathering preliminary information of the concern. After 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. TECH LINE will confirm with DENSO, by email, that the diagnosis has occurred and a DCU
replacement is approved.
NOTE:

TECH LINE will not send an email or fax to your parts department.

Approval from TECH LINE does not mean the DCU has been ordered. The DCU
can be ordered from DENSO only after approval from TECH LINE (see page 4).

6. After the order is submitted, and after TECH LINE has submitted authorization by email,
then DENSO will email confirmation to your parts department that the order has been
placed.*
* The DCU order approval process does not apply to 2017 Pathfinder vehicles. TECH
LINE authorization is not needed for 2017 Pathfinder vehicles. This process does
not apply to 2017 Armada since it uses a different system. For 2017 Pathfinder,
