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.
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.

SERVICE PROCEDURE
Reprogram the ECM
IMPORTANT: Before starting the reprogramming procedure, 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.



The CONSULT PC is connected to the Internet (Wi-Fi or cable).

NOTE:


If you are not familiar with the reprogramming procedure, click here. This will link to the "CONSULTIII PLUS (C-III PLUS) ECM Reprogramming" general procedure.



Take the vehicle for a 10 minute drive in order to meet the following Idle Air Volume Learn (IAVL)
conditions:
 Engine coolant temperature: 70-100°C
(158-212°F)
 Battery voltage: More than 12.9V (At idle)
 Transmission: Warmed up



After reprogramming is complete, it is required to perform
Throttle Valve Closed Position, Idle Air Volume Learn,
Accelerator Closed Position, and DTC Erase.
Figure 1



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 above 15.5V during reprogramming, the ECM may
be damaged.



Be sure to turn OFF all vehicle electrical loads. If a vehicle electrical load remains ON, the ECM
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 ECM may be damaged.



Turn OFF all external Bluetooth® devices (e.g., cell phones, printers, etc.) within range of the
CONSULT PC and the plus VI. If Bluetooth® signal waves are within range of the CONSULT PC
and the plus VI during reprogramming, reprogramming may be interrupted and the ECM may be
damaged.
