Classification: Reference: Date: EM19-007 ITB19-021 August 23, 2019 2019 QX50; DRIVE BELT CHIRP NOISE APPLIED VEHICLE: 2019 QX50 (J55) IF YOU CONFIRM The drive belt makes a chirp type noise when accelerating the vehicle and/or revving the engine in Park. ACTION Compare the vehicle’s ECM and TCM part numbers with those listed in TABLE A and TABLE B, respectively, in this bulletin. If there is a match, reprogram the ECM. If there is a match, also reprogram the TCM. 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. 1/4 SERVICE PROCEDURE ECM Reprogramming 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). HINT: If you are not familiar with the reprogramming procedure, click here. This will link to the "CONSULT-III PLUS (C-III PLUS) ECM or TCM 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. 1. Using C-III plus, confirm the current ECM part number and write it on the repair order. If it matches one of the part numbers in Table A (next page), reprogram the ECM, and then confirm if the TCM needs to be reprogrammed (see TCM Reprogramming on the next page). If it does not match any of the part numbers in Table A, go to TCM Reprogramming on the next page. 2/4 ITB19-021 Table A CURRENT ECM PART NUMBER: 23710 – 5NC0D, 5NC1D, 5NC2D, 5NC3D, 5NC0E, 5NC1E, 5NC2E, 5NC3E, 5NE0A, 5NE1A, 5NE2A, 5NE3A, 5NE0B, 5NE1B, 5NE2B, 5NE3B, 5NE0C, 5NE1C, 5NE2C, 5NE3C, 5NE0D, 5NE1D, 5NE2D, 5NE3D, 5NE0E, 5NE1E, 5NE2E, 5NE3E, 5NF0B, 5NF1B, 5NF2B, 5NF3B, 5NF0C, 5NF1C, 5NF2C, 5NF3C, 5NL0A, 5NL1A, 5NL2A, 5NL3A, 5NL0B, 5NL1B, 5NL2B, 5NL3B, 5NL0C, 5NL1C, 5NL2C, 5NL3C, 5NL0D, 5NL1D, 5NL2D, 5NL3D, 5NL0E, 5NL1E, 5NL2E, 5NL3E, 2. 5NC4D, 5NC4E, 5NE4A, 5NE4B, 5NE4C, 5NE4D, 5NE4E, 5NF4B, 5NF4C, 5NL4A, 5NL4B, 5NL4C, 5NL4D, 5NL4E, 5NC5D, 5NC6D, 5NC7D, 5NC8D 5NC5E, 5NC6E, 5NC7E, 5NC8E 5NE5A, 5NE6A, 5NE7A, 5NE8A 5NE5B, 5NE6B, 5NE7B, 5NE8B 5NE5C, 5NE6C, 5NE7C, 5NE8C 5NE5D, 5NE6D, 5NE7D, 5NE8D 5NE5E, 5NE6E, 5NE7E, 5NE8E 5NF5B, 5NF6B, 5NF7B, 5NF8B 5NF5C, 5NF6C, 5NF7C, 5NF8C 5NL5A, 5NL6A, 5NL7A, 5NL8A 5NL5B, 5NL6B, 5NL7B, 5NL8B 5NL5C, 5NL6C, 5NL7C, 5NL8C 5NL5D, 5NL6D, 5NL7D, 5NL8D 5NL5E, 5NL6E, 5NL7E, 5NL8E After completing Erase ALL DTCs, print a copy of the C-III plus screen showing the before and after ECM part numbers and attach it to the repair order. TCM Reprogramming HINT: C-III plus, the CONSULT PC, the AC adaptor, and the battery maintainer or smart charger should still be connected to the vehicle. If not, make sure the items under IMPORTANT below have been applied. IMPORTANT: Before starting the reprogramming procedure, make sure: 3. 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). Using C-III plus, confirm the current TCM part number and write it on the repair order. If it matches one of the part numbers in Table B, reprogram the TCM. If it does not match any of the part numbers in Table B, no further repairs are needed.
