2021-2023 Nissan Infotainment Control Unit Replacement TSB

What this TSB addresses

This Technical Service Bulletin (TSB) from Nissan provides crucial service information regarding the replacement of the AV Control Unit, also known as the infotainment control unit. It emphasizes that a specific, sequential three-step procedure must be followed whenever this unit is replaced for any reason.

Why the correct procedure is critical

Failing to complete all three required steps in the correct order can lead to significant issues. Specifically, if your vehicle is equipped with a Telematics Control Unit (TCU), Over The Air (OTA) updates will not function. Additionally, other critical infotainment system functions may become inoperative, impacting your driving experience and access to vehicle features. This TSB ensures that the new Nissan infotainment control unit is properly integrated and fully functional.

The three-step replacement process

When replacing an AV Control Unit (infotainment control unit), technicians must perform the following steps in the exact order specified:

1. Reprogram the AV control unit: The new unit must first be reprogrammed to ensure it has the latest software and is compatible with the vehicle's systems.
2. Configure the AV control unit: After reprogramming, the unit needs to be configured specifically for your vehicle's features and settings.
3. Write the VIN to the AV control unit: Finally, the vehicle's unique Vehicle Identification Number (VIN) must be written to the new AV control unit. This step is essential for proper system identification and functionality.

Nissan notes that not all affected vehicles are OTA-update capable, but the procedure remains critical for all replacements.

Important warnings for owners

Owners should be aware that if their Nissan infotainment control unit is replaced and these three steps are not followed precisely, the vehicle's Over The Air (OTA) update capability may be lost. Furthermore, other functions of the infotainment system could become inoperative. It is crucial to ensure that any service center replacing your infotainment unit is aware of and follows this specific Nissan procedure.

Owner action

If your 2021-2023 Nissan Rogue, Titan, Pathfinder, Frontier, or Armada requires an infotainment control unit replacement, ensure your service technician is aware of and follows Nissan's mandatory three-step procedure. This will prevent issues with OTA updates and other infotainment system functionalities. If you experience problems with your infotainment system after a recent replacement, contact your Nissan dealer to verify the correct procedure was followed.
