2014-2015 Q50 AND Q50 HYBRID; STRONG ODOR INSIDE VEHICLE
This bulletin has been amended in the Title, APPLIED VEHICLES, and IF YOU CONFIRM.
No other changes have been made. Discard all previous versions of this bulletin.
APPLIED VEHICLES: 2014-2015 Q50 (V37)
2014-2015 Q50 Hybrid (V37)
APPLIED VINs and
DATES: All vehicles built before JN1BV7AP(*)FM 332566 and October 14, 2014
JN1BV7AR(*)FM 393189 and October 14, 2014
JN1AV7AP(*)FM 790218 and October 14, 2014
JN1AV7AR(*)FM 850209 and October 14, 2014
IF YOU CONFIRM
A strong sulfur like odor is coming from the Moonroof drain hoses after a hot soak (after sitting with doors and
windows closed).

Odor is most noticeable if the Moonroof shade is left closed while the vehicle sits in the direct sunlight
and then after a hot soak the Moonroof shade is opened.
NOTE: The Moonroof drain hoses MUST be the cause of the strong sulfur like odor for this bulletin to
apply.
ACTION

Replace the Moonroof drain hoses with the Service Procedure starting on the next page.
And

Deodorize with an ozone generator as needed.
And then

Replace in-cabin microfilter.
IMPORTANT: The purpose of “ACTION” (above) is to give you a quick idea of the work you will be performing.
You MUST closely follow the entire Service Procedure as it contains information that is essential to successfully
completing the repair.
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.

14. Confirm that the odor is gone.


If odor is not completely gone, proceed to “Odor Removal with Ozone Machine”.
If odor is gone, proceed to “Resetting Customers Settings” on page 13.
Odor Removal with Ozone Machine
1. Connect the GR8 (Multitasking Battery Diagnostic Station) to the vehicle’s 12V battery.

Set the GR8 to ECM power supply mode.
2. Depress the vehicle’s power (“ignition”) switch twice without depressing the brake pedal.

The meter and gauges will illuminate.
CAUTION: For Q50 Hybrid, Do Not set the vehicle in “READY to drive” mode and make sure the ready
to drive indicator light is OFF (not illuminated)..
Ready to drive indicator light
(Make sure it is OFF)
Figure 19
3. Turn the Climate Control “ON” and set the Mode to Recirculation.
4. Set the fan speed to the highest setting.
NOTE: This will allow the ozone to circulate through the Instrument Panel ducts and help distribute the
ozone throughout the vehicle over the 4 hour treatment.
10/14
ITB14-039b
5. Remove the TechMate ozone machine
(Rainbowair Activator 1000 - II Mobile Station, part
number #188-5401-II MS), foam inserts (Figure
21) and ducting hose from its storage case.
Ozone machine
6. Place the ozone machine on top of the storage
case.
7. Fold down the rear seat arm rest, and then open
the pass through access panel to the trunk that is
located behind the arm rest.
NOTE: This will allow the ozone to reach the trunk
area.
Figure 20
8. Close all windows, doors, and Moonroof.
Foam inserts
9. Roll down either the passenger or driver’s side
window half way.
10. Insert the foam from kit (Shown in Figure 21) into
chosen window, and then close window until snug
fit is achieved.
NOTE: Confirm that any gaps in the foam are as
small as possible. This will prevent ozone from
escaping.
Figure 21
11. Connect the duct hose to the ozone machine and
then the other end into the hole provided in the
foam inserts.

12. Set the ozone machine’s OUTPUT to 10 and the
HOURLY TIMER to 2.
13. Toggle the POWER switch to TIMER. This will
start the flow of ozone.
After 2 hours the machine will shut off.

14. Once the machine has shut OFF, leave it attached and the vehicle sealed for an additional 2 hours.
IMPORTANT: The process of deodorization takes place after the machine has shut
OFF. The vehicle MUST be left closed as this process takes place.
15. After the vehicle has sat with the ozone machine OFF for 2 hours, open the vehicle (all doors, trunk,
Moonroof) and allow it to air out for an hour.
NOTE: This will allow the ozone that has captured these odors to leave the vehicle.
 If possible (season and weather permitting), park the vehicle outside in direct sunlight to raise interior
cabin temperatures. This will allow more odor to be eliminated from the interior trim.
16. Turn OFF the Climate Control when the vehicle has aired out enough to allow entry.
17. Confirm that the odor is gone.
18. If some of the odor is still present, repeat Steps 8-17 as many times as needed until the odor is removed.
19. Replace the vehicle’s in-cabin microfilter.
NOTE: Refer to the ESM, section VTL – Ventilation System, for procedure to replace the in-cabin
microfilter.

4. If equipped, reset the customer preferred settings for the Automatic Air Conditioning System.

If needed, refer to System Settings in the HAC section of the ESM.
5. Inform the customer:

If equipped, some memory settings in the navigation system may need to be reset.
6. Reinitialize and check the Anti-Pinch Function for all Auto-UP power windows:
Reinitialize:
a. Turn the ignition ON.
b. Operate the power window switch to fully open the window (glass all the way down).
c. Hold the window switch UP until the glass stops at the fully closed position, and then continue holding the
switch UP for 2 seconds or more.
d. Check that AUTO-UP function operates normally.
Check Anti-Pinch Function
a. Fully open the door window (glass all the way down). b. Hold a piece of wood near the fully closed
position.
c. Close the door window glass using the AUTO-UP switch. Allow the window glass to hit the wood. d.
Check the following conditions:
 Check that the glass lowers for approximately 150 mm (5.9 in), without pinching the wood, and stops.
 Check that the glass does not rise when operating the power window main switch, while the widow is
lowering after hitting the wood.
CAUTION: Do not check anti-pinch function with hands or other body parts because they may be pinched.
