INTRODUCTION
Nissan is conducting a voluntary service campaign on certain specific model year 20042011 Titan, and 2005-2011 Frontier and Xterra vehicles to reprogram the air bag diagnosis
sensor unit. This repair will be performed at no charge to the customer for parts or labor.
IDENTIFICATION NUMBER
Nissan has assigned identification number P7318 to this campaign. This number must
appear on all communications and documentation of any nature dealing with this campaign.
DEALER RESPONSIBILITY
Dealers are to repair vehicles falling within range of this campaign that enter the service
department. This includes vehicles purchased from private parties, vehicles presented by
transient (tourists) owners, and vehicles in a dealer’s inventory.
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.

REQUIRED SPECIAL TOOL J-51594 (SRS Reprogramming Cable)
This disc, supplied
with the cable, is
not needed for this
bulletin’s procedure
Figure 1
NOTE: One J-51594 SRS reprogramming cable (J-51594 cable or blue cable) has
been supplied to each dealer. Additional blue cables can be obtained from
Tech•Mate at 1-800-662-2001.
SERVICE PROCEDURE
IMPORTANT: Before starting, make sure:

ASIST on the CONSULT PC has been freshly synchronized (updated to the
current date).

All C-III plus software updates (if any) have been installed.
NOTE:
 The CONSULT PC automatically gets applicable reprogramming data during
ASIST synchronization.
 Refer to page 9, Error Messages, if an error message appears on the
C-III plus screen during the reprogram process.

Make sure the driver for the blue cable is installed/updated:
a. Connect the CONSULT PC to the Internet.
b. Connect the blue cable to the CONSULT PC USB port.
c. Wait one (1) minute, the drivers will install / update automatically.
NOTE: Steps a-c above are only required one time to install the driver into the
CONSULT PC. But it is recommended that steps a-c above be performed at the
beginning of each day to confirm the latest software has been installed.

Reprogramming Procedure
NOTE: The screen shots in this bulletin are similar to, if not the same as, those on your
CONSULT PC.
1. At this time, do not turn the ignition ON.
2. Connect the blue cable to the vehicle’s DLC connector and the PC USB port.

Make sure the blue cable is securely connected at both ends.
CAUTION: Make sure the J-51594 cable is securely connected. If the J-51594 cable
connection is loose during reprogramming, the process will be interrupted and the
air bag diagnosis sensor unit may be damaged.
3. Connect the AC Adapter to the CONSULT PC.
CAUTION: Be sure to connect the AC Adapter. If the CONSULT PC battery voltage
drops during reprogramming, the process will be interrupted and the air bag
diagnosis sensor unit may be damaged.
4. Connect the GR-8 battery charger to the vehicle battery and select ECM Power Supply
Mode.
CAUTION: Be sure the battery charger is connected securely to the battery. Make
sure the battery voltage stays between 12.0V and 15.5V during reprogramming. If the
battery voltage goes out of this range during reprogramming, the air bag diagnosis
sensor unit may be damaged.
5. Turn OFF all vehicle electrical loads such as exterior lights, interior lights, HVAC,
rear defogger, audio, NAVI, seat heater, steering wheel heater, etc.
IMPORTANT: Make sure to turn OFF all vehicle electrical loads. Make sure the
battery voltage stays between 12.0V and 15.5V during reprogramming. If the battery
voltage goes out of this range during reprogramming, the air bag diagnosis sensor
unit may be damaged.
