2021-2022 Nissan Sentra Intelligent Key Not Detected TSB

Symptoms

The primary symptom addressed by Nissan Technical Service Bulletin NTB22-014A is when "The Intelligent Key fob is not detected when above or around the center console area." This means the vehicle's system fails to recognize the key fob when it's placed in or near the center console. This issue can prevent the vehicle from starting or operating correctly, leading to inconvenience and potential stranding.

Diagnosis / Trigger Conditions

This specific condition applies to 2021 Nissan Sentra vehicles of all grades and 2022 Nissan Sentra vehicles built before June 7, 2022, specifically the S grade. If your vehicle falls within these production parameters and exhibits the "Intelligent Key not detected in center console" symptom, it is likely affected by this technical service bulletin. The issue stems from a software configuration within the Hands Free Module (HFM).

Repair Procedure Summary

Nissan Technical Service Bulletin NTB22-014A outlines a detailed procedure for technicians to reconfigure the Hands Free Module (HFM) in affected 2021-2022 Nissan Sentra vehicles. This process requires the use of the CONSULT PC, ensuring it has synchronized ASIST and all CONSULT software updates installed.

The technician begins by connecting the CONSULT PC to the vehicle via the Vehicle Interface (VI) and turning the ignition ON while the engine remains OFF. They then launch the C-III plus software and log in using their credentials. From the diagnostic menu, the technician selects the "Re/programming, Configuration" option.

After reviewing and confirming various precautions, the system performs an automatic VIN selection to identify the vehicle. The technician then navigates to the system selection menu and chooses "HANDS FREE MODULE." Under the "VEHICLE CONFIGURATION" section, "After ECU Replacement" is selected, followed by "Manual selection."

The final step involves selecting the specific "Type ID 285J7-6LE3A" for the Hands Free Module. The technician then proceeds to write this configuration to the vehicle's system. Once the configuration is successfully written and confirmed, the repair process is complete, resolving the Nissan Sentra key not detected issue.
