PART 1:
Confirm Proper Diagnosis and Repair with TECH LINE to Obtain Display Control Unit Order Approval,
Then Place the Order with DENSO
NOTE: The DCU order approval process does not apply to 2014-2015 Q50 and Q50 Hybrid vehicles. Proceed
to Order an Exchange DCU From DENSO on page 4.
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 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 must be ordered from
DENSO.



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 contacting 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.

2/17

ITB13-026h

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: While not required, Infiniti 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:


Steps 1-4, below, do not apply to 2014-2015 Q50 and Q50 Hybrid vehicles. Proceed to Order an
Exchange DCU From DENSO on page 4.



Contacting TECH LINE is done to confirm diagnosis. An exchange DCU must be ordered by your parts
department directly from DENSO.

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 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. 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.



Approval from TECH LINE does not mean the DCU has been ordered. The DCU must be ordered
from DENSO (see page 4).
