INTRODUCTION

Infiniti is conducting this voluntary recall campaign, on certain specific model year 2021 Q50, Q60, and QX80 vehicles, to reprogram the Telematics Control Unit (TCU). This service will be performed at no charge to the client for parts or labor.

 

IDENTIFICATION NUMBER

Infiniti has assigned identification number R21A9 to this campaign. This number must appear on all communication and documentation of any nature dealing with this campaign.

 

RETAILER RESPONSIBILITY

It is the  retailer’s responsibility to check Service COMM or Dealer Business Systems (DBS) National Service History for the campaign status on each vehicle falling within the range of this voluntary recall which for any reason enters the service department. This includes vehicles purchased from private parties or presented by transient (tourist) owners and vehicles in a retailer’s inventory.  Federal law requires that new vehicles in retailer inventory which are the subject of a recall must be corrected prior to sale.  Failure to do so can result in civil penalties by the National Highway Traffic Safety Administration.  While federal law applies only to new vehicles, Infiniti strongly encourages retailers to correct any used vehicles in their inventory before they are retailed.

 

SERVICE PROCEDURE

 

Reprogram the TCU

 

IMPORTANT: Before starting, make sure:

• ASIST on the CONSULT PC has been synchronized (updated) to the current date.
• All C-III plus software updates (if any) have been installed.

 

• Connect a battery maintainer/smart charger set to reflash mode or a similar setting. If the vehicle battery voltage drops below 12.0V or rises above 15.5V during reprogramming, the TCU may be damaged.

 

• Be sure to turn OFF all vehicle electrical loads. If a vehicle electrical load remains ON, the TCU 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 TCU 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 or VI during reprogramming, reprogramming may be interrupted and the TCU may be damaged.

 

1. Turn ON the ignition and the hazard warning lights.

 

2. Connect the VI to the vehicle.

 

3. Start C-III plus.

 

4. Wait for the VI to be recognized.

 

• The serial number will display when the VI is recognized, as shown in Figure 1 on page 3.

 

5. Select Re/programming, Configuration.

11. Select Reprogramming.

 

12. Find the TCU Part Number and write it on the repair order, and then select Save.

 

NOTE: This is the current Part Number (P/N).

 

• If the current TCU part number is 28275-5SN9B, proceed to step 13 on page 7.
• If the current TCU part number is not 28275-5SN9B, reprogramming is not required. Skip to Claims Information on page 14.

 

13. Check the box to confirm the precaution instructions have been read, and then select Next.

 

NOTE: Use the arrows (if needed) to view and read all the precautions.

 

14. Read the Current Part Number and Part Number After Repro/programming. They should be different, and then select Next.

 

15. Confirm the battery charger is ON and the battery voltage is between 12V-15.5V.

 

16. Select Next.

 

• To avoid damage to the TCU, ensure the ignition is ON and the hazard warning lights are also ON, as the update will take approximately 45 minutes to complete.
• To avoid damage to the TCU, ensure a battery maintainer or smart charger, set to reflash mode or a similar setting, is connected.
• To avoid damage to the TCU, ensure the AC Adapter is connected to the CONSULT PC.

Tutorial for Purchasing NERS Software

Software updated April 26, 2019 to version # 04.03.00. It is recommended the latest version of NERS be installed before connecting to a vehicle.

This NERS software supports reprogrammable Engine and Transmission control units from 1999 to 2019 model year vehicles, and 2005 MY and later VIN writing into ECUs, when using a Nissan validated pass-through device. Click the Reprogramming Tab for additional information on reprogramming. This software only provides ECU reprogramming, blank programming and VIN writing capability.
