Refer to step 6 in the SERVICE PROCEDURE to confirm this bulletin applies to the vehicle you are working on. 2. If this bulletin applies, reprogram the ECM. 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. 1/12 SERVICE PROCEDURE ECM Reprogram IMPORTANT: Before starting, make sure: ASIST on the CONSULT PC has been synchronized (updated) to the current date. All CONSULT software updates (if any) have been installed. NOTE: Most instructions for reprogramming with CONSULT are displayed on the CONSULT PC screen. If you are not familiar with the reprogramming procedure, click here. This will link you to the "CONSULT Reprogramming" general procedure. Preparation for Reprogramming Take the vehicle for a 10 minute drive in order to meet the following Idle Air Volume Learn (IAVL) conditions: o Engine coolant temperature: 70 -100°C (158 - 212°F) o Battery voltage: More than 12.9V (At idle) o Transmission: Warmed up Figure A After reprogramming is complete, you will be required to perform Throttle Valve Closed Position, Idle Air Volume Learn, Accelerator Closed Position, and DTC erase. CAUTION: Connect a battery maintainer or smart charger, set to reflash mode or a similar setting, to ensure the battery voltage stays between 12.0 V and 15.5 V.. 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 VI. If Bluetooth® signal waves are within range of the CONSULT PC during reprogramming, reprogramming may be interrupted and the ECM may be damaged. 2/12 ITB17-050A 1. Connect the VI to the vehicle. 2. Start CONSULT. 3. Wait for the VI to be recognized. The serial number will display when the VI is recognized (Figure 1). 4. Select Re/programming, Configuration. Figure 1 5.
