ACTION
Refer to step 14 on page 8 to confirm if the A/C Amplifier must be replaced, can be
reprogrammed, or if this bulletin applies.
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 this repair.
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.

SERVICE PROCEDURE
IMPORTANT: Before starting, make sure:

ASIST on the CONSULT PC has been synchronized (updated) to the current date.

All CONSULT-III plus (C-III plus) software updates (if any) have been installed.

Connect a battery maintainer or smart charger set to reflash mode or a similar
setting. If the vehicle battery voltage drops below 12.0V or rises above 15.5V
during reprogramming, the A/C Amplifier may be damaged.

Be sure to turn OFF all vehicle electrical loads.
If a vehicle electrical load remains ON, the A/C Amplifier may be damaged.

Be sure to connect the AC Adapter.
If the CONSULT PC battery voltage drops during reprogramming, the process
will be interrupted and the A/C Amplifier may be damaged.

Turn OFF all external Bluetooth® devices (e.g., cell phones, printers, etc.)
within range of the CONSULT PC and the VI. If Bluetooth® signal waves are
within range of the CONSULT PC or VI during reprogramming, reprogramming
may be interrupted and the A/C Amplifier may be damaged.
1.
Connect the VI to the vehicle.
2.
Start C-III plus.
3.
Wait for the VI to be recognized.

The serial number will display when the VI is recognized (see Figure 1 on
page 3).
