SERVICE INFORMATION
If a customer describes a concern of a door not opening and/or unlocking properly, on any
of the APPLIED VEHICLES, use the Questions for the Customer below to help
reproduce the concern, and then follow the SERVICE PROCEDURE starting on page 2 to
determine if the Door Lock should be replaced.

Do not replace a Door Lock unless instructed to by the SERVICE PROCEDURE.
Questions for the Customer:

When did you first notice the issue?

Is it consistent or intermittent?

Under what conditions does it occur?

Does it seem more likely to happen to a specific passenger/person in your family?

Has there been any change to the issue since it first began?
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
IMPORTANT: Please follow the complete SERVICE PROCEDURE, below, to confirm and
diagnose Door Lock concerns.
Door Sticking, Will Not Open, or Will Not Close
1.
Confirm the concern and document it on the repair order.




Door will not open
Door will not close
Door sticks in half-lock position
Other concern
2.
Confirm if the concern affects the operation of both the inside and the outside handles
of the affected door, or just one (1) handle.
3.
Check the position of the "manual" Inside Lock Knob located on the Inside Handle of
the affected door, and take a photo.

If the Inside Lock Knob is positioned somewhere between fully locked and fully
unlocked, it can result in the door becoming stuck in the half-lock position, and
cause the power lock to be unresponsive.
o This can be caused by contact
with the Inside Lock Knob as
the Inside Handle is actuated to
open the door from inside the
vehicle and is not a defect. Do
not replace the Door Lock as it
can happen just as easily with
the replacement Door Lock.
o Demonstrate to the customer
what is believed to be causing
their concern.
a. Show that it is possible to
inadvertently move the
Inside Lock Knob with the
heel of your hand when
pulling the Inside Handle to
exit the vehicle.

b. If the concern happens again, ask the customer to confirm if the Inside
Lock Knob is partially or fully locked. The concern should be resolved by
manually unlocking the door with the Inside Lock Knob.

If this concern is confirmed, a slightly altered approach to opening the
door can be used to avoid inadvertent contact with the Inside Lock
Knob.
c. If the issue persists and it is confirmed that the Inside Lock Knob was not
moved, proceed to step 4.
The Concern is Present Despite The Inside Lock Knob Position
4.
Confirm if the concern is due to poor door fit.

5.
6.
Adjust the Front Door Striker as needed, and then retest for correct operation.
Confirm that the Front Door Lock is installed properly, fully secured and properly
aligned in the door opening.

Take a photo of any concerns found for documentation.

Resolve concerns as needed, and then retest for correct operation.
Carefully remove the Front Door Finisher.
a. Does the door now function properly with the Front Door Finisher removed?
o Inspect the Inside Handle base for anything that could cause the concern.
 Replace any suspected components as needed, and then retest for correct
operation (these components may be collected).
b. Confirm that the Front Door Lock cables are correctly routed and attached.
o Document any abnormal cable concerns found.
o Correctly route and/or reattach the cables as needed, and then retest for
correct operation.
c. Confirm that the cables are not bent or kinked.
o Take a photo of any concerns found for documentation.
o If bent or kinked, replace the Front Door Lock and then confirm correct
operation.
d. If the concerns in steps 6a-6c were not present and the concern is still present,
replace the Front Door Lock, and then retest for correct operation.
o Make note of any concerns found for documentation.

NTB22-104
One or More Power Door Locks Seem to Have an Electrical Concern
7.
Confirm if the concern is present in only a single door or in multiple doors, and if the
condition is consistent or intermittent.
a. Confirm if the inoperative actuator is making any sound when lock/unlock is
requested.
b. Check the position of the "manual" Inside Lock Knob located on the Inside Handle
of the door with the concern, and then take a photo.
o If the Inside Lock Knob is positioned somewhere between fully locked and fully
unlocked, it can result in the door becoming stuck in the half-lock position, and
cause the power lock to be unresponsive.

8.
Confirm that the Inside Lock Knob of the affected door operates correctly.

9.
See step 3 on pages 2 and 3 for more detail.
If the affected Inside Lock Knob has a noticeably higher resistance, as compared
to the other doors' Inside Lock Knobs, document it on the repair order and then
proceed to step 9.
Remove the affected Door Finisher, but do not detach the Door Lock's cable yet.

Does the Door Lock now work correctly after removing the Door Finisher?
o There may be resistance within the lock cable that was relieved by altering the
cable routing. Reposition the cable as needed, and then retest for correct
operation.
o If the concern can be duplicated, document the occurrence with photos and/or
video (see footnote 1 on page 5).
10.
11.
Confirm that the affected Door Lock cables are correctly routed and attached.

Document any abnormal cable concerns found.

Correctly route and/or reattach the cables as needed, and then retest for correct
operation.
Confirm that the affected door's wiring harness connector is fully engaged to the Door
Lock actuator.

12.
Reengage as needed, and then retest for correct operation.
Does the Door Lock work after slightly repositioning or wiggling the door wiring
harness, or after disconnecting it for several seconds and then reconnecting it?

If so, this could be a connectivity issue of the wiring harness connector or in the
wiring harness. If the concern can be duplicated, document the occurrence with
photos and/or video (see footnote 1 on page 5).

If a wiring harness/connectivity issue is confirmed, replace the Door Lock actuator
and associated wiring harness, and then retest for correct operation (see footnote
2 on page 5).

NTB22-104
If The Concern Persists Despite Cable and Harness Position Adjustment
13.
Carefully detach the Door Lock cable from the Inside Handle, taking note of the
orientation of the cable end after it is detached.

Confirm the orientation of the cable end after it is detached.
o Did the cable end spin or unwind when released? If so, which way? Document
anything found on the repair order.
HINT: Is it possible that the cable was wound in a direction that bound it?
14.
Does the Door Lock operate correctly with the end of the lock cable detached from the
Inside Handle?

Yes: Reattach the Door Lock cable to the Inside Handle, reassemble the Door
Finisher and then retest for correct operation.

No: Replace the Door Lock actuator and the door wiring harness (unless the issue
is clearly unrelated to the Door wiring harness), and then retest for correct
operation (see footnote 2, below).
(1)
Photos/videos can be taken with personal devices (photos/videos may be helpful to
Engineering staff following up on the concern, but are not required). Please plan to
retain any photos/videos for a period of three (3) weeks if possible. Please include a
note or reference to available photos/videos in repair order documentation.
(2)
For any part(s) replacement required, please refer to standard work instruction(s) for
the respective part(s).
