SERVICE INFORMATION
The APPLIED VEHICLES that come equipped with a factory installed SOS switch, located
near the overhead map lamp, also come equipped with a wireless communication device
called a Telematics Communication Unit (TCU). With an active NissanConnect® Services
subscription, the TCU communicates with the Nissan Data Center to provide various
security and convenience services.
CONSULT has been updated to allow DTC B2E01-96 (Internal battery) to be cleared in the
TCU.
If DTC B2E01-96 is Current/Active in the TCU, and no additional Current/Active DTCs are
present in the TCU, perform the SERVICE PROCEDURE starting on page 2.
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 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 TCU may be damaged.

Be sure to turn OFF all vehicle electrical loads.
If a vehicle electrical load remains ON, the TCU 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 TCU 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 TCU may be damaged.
