RETRACTABLE HARD TOP INITIALIZATION SERVICE INFORMATION
APPLIED VEHICLES: 2009-2013 G37 Convertible (V36)
2014-2015 Q60 Convertible (V36)

SERVICE INFORMATION
If the battery becomes disconnected or discharged while the retractable hard top is in any position other than
fully closed or fully retracted, the retractable hard top control may stop operating and the following DTCs will be
stored: B1707 and B1708. Other retractable hard top related DTCs may also be found stored. To restore
operation: (1) close the roof fully manually; (2) erase the DTC(s); and (3) perform hard top control unit
initialization.
This bulletin provides the procedures to restore retractable hard top control operation.

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
NOTE: Before starting the service procedure, make sure the battery is sufficiently charged and both battery
cables are connected.
CAUTION: Use of the Work Support feature in this bulletin may result in the retractable hard top functioning out
of sequence. If interference conditions occur with the parcel shelf, flipper doors, and trunk/roof latches, damage
may occur.

1. Connect the GR-8 (Battery and Electrical Diagnostic Station) or suitable battery charger to the vehicle
battery, and then set at low charge.
2. Connect the CONSULT PC and plus VI to the vehicle, and then start CONSULT-III plus (C-III plus).
2a. Wait for the plus VI to be recognized / connected.


The serial number will display when the plus VI is recognized / connected.

3. Select Diagnosis (One System).

8. Using C-III plus, fully close the retractable hard top (roof).


Use the list below to determine where to start manually closing the roof.
NOTE:
 The roof will need to be closed in the correct order of each related component from OPEN
to CLOSE. For example, if the trunk is fully lifted but the flipper doors are closed halfway, the first
component to be moved (closed) would be the flipper doors, and then the roof latches, etc. Which
component needs to be closed first will depend on the roof’s current “state” of open position. By
using the list below, first determine the roof’s state, and then close the roof starting at the
determined position.


When giving the command in C-III plus to open, close, go up, down, etc. a given component, the
related on-screen button may need to be clicked (tapped) rapidly multiple times to complete the
requested sequence. Pressing once or pressing and holding down may not work.
CAUTION: Use of the Work Support feature in this bulletin may result in the retractable hard top
functioning out of sequence. If interference conditions occur with the parcel shelf, flipper doors,
and trunk/roof latches, damage may occur.

From the full open position (roof stored in the trunk), the components are being operated toward the closed
position in the following order:
a. trunk opener (go to page 6)
b. trunk open (go to page 9)
c. parcel shelf angle direction vertical (go to page 9)
