IMPORTANT: The purpose of ACTION (on the next page) 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.
Infiniti 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 Infiniti retailer to determine if this
applies to your vehicle.

ACTION
Reprogram the ABS control unit (ABS) per the Service Procedure in this bulletin.


Part of the Service Procedure, step 20 on page 8, is a confirmation that reprogramming is needed to
resolve the incident shown in Figure A and B on page 1.

SERVICE PROCEDURE
IMPORTANT: Before starting, make sure:


ASIST on the CONSULT PC has been synchronized to the current date.



All CONSULT-III plus (C-III plus) software updates (if any) have been installed.
NOTE: The CONSULT PC automatically gets applicable reprogramming data during ASIST
synchronization.



A screen print for Warranty documentation can be done from the CONSULT PC during this process
while still connected to the vehicle.



No DTCs stored.
 Use C-III plus to perform Self Diagnosis for all systems.
 If there are any DTCs other then C1A27, diagnose, perform repairs, and erase DTCs before
continuing.
 If only DTC C1A27 is stored, erase DTC before continuing.

1. Connect the plus VI to the vehicle.
CAUTION: Make sure the plus VI is securly connected. If the plus VI connection is loose during
reprogramming, the process will be interrupted and the the control unit may be damaged.

2. 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 control unit may be damaged.

ITB14-051a

3. Connect the GR8 and set to “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 control unit may be damaged.

4. Turn OFF all external Bluetooth® devices (e.g., cell phones, printers, etc.) within range of the CONSULT
PC and the VI.
CAUTION: Make sure to turn off all external Bluetooth® devices. If Bluetooth® signal waves are within
range of the CONSULT PC and the VI during reprogramming, reprogramming may be interrupted, and
the control unit may be damaged.

5. Turn the ignition ON with the engine OFF.


The engine must not start or run during the reprogramming procedure.

6. Turn OFF all vehicle electrical loads such as exterior lights, interior lights, HVAC, blower, 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 control unit may be damaged.

7. Turn ON the CONSULT PC.

8. Select CONSULT-III plus (open C-III plus).
