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.

NOTE: Steps 2a, b, & c MUST be done in close time and sequence together in order for
the test to be performed correctly.
2a. Open the door, enter the vehicle, and then close the door. Press the ignition button, and
then immediately perform step 2b.

At this time, due to no Intelligent Key in or around the vehicle, the BCM will activate
only the ignition switch antenna.
Ignition switch antenna will become
active and will transmit a signal to
detect any Intelligent Key in range
Figure 3
2b. WITHIN 30 SECONDS of step 2a above, FIRST have an associate hand the Intelligent
Key to you, THEN immediately perform step 2c.
Have an associate deliver
the incident Intelligent Key
WITHOUT HAVING TO
OPEN THE DOOR
Figure 4
2c. Place the Intelligent Key next to the ignition button as shown in Figure 5 below
(emblems align with center of buttons). Do not depress the ignition button.
Place Intelligent Key next to
ignition button and wait for tones
Figure 5

If two short tones are heard, the Intelligent Key was de-synchronized but is now
re-synchronized and should function normally again. See step 3, Figure 6 (next
page).

If no tones are heard and the Intelligent Key buttons still do not work, refer to ASIST
or the applicable Electronic Service Manual for further diagnosis.
