Nissan has issued Technical Bulletin NTB20-073B to provide updated service information for the Intelligent Key unit, also known as the hands-free module. This bulletin is crucial for technicians performing a Nissan Intelligent Key unit service to ensure proper functionality and prevent potential issues after replacement.
What is the Intelligent Key Unit?
The Intelligent Key unit is a critical component of your vehicle's hands-free entry and ignition system. It communicates wirelessly with your Nissan's onboard systems, allowing you to lock/unlock doors and start the engine without physically inserting a key. When this unit requires replacement, specific procedures must be followed to integrate the new component correctly with the vehicle's security system.
Key Service Procedures for Intelligent Key Unit Replacement
When replacing the Intelligent Key unit, Nissan mandates a precise sequence of steps to ensure the new unit functions correctly and securely. Technicians are instructed to ALWAYS replace it with a new one.
The most critical step involves module configuration and NATS (Nissan Anti-Theft System) initialization. The bulletin explicitly states that module configuration MUST BE performed before NATS initialization (key registration). This sequence is vital because, once NATS initialization has been completed, certain portions of the configuration become locked and cannot be altered.
For specific procedural details, technicians are directed to consult the Electronic Service Manual (ESM). The navigation paths within the ESM vary slightly by model:
- For Pathfinder (R53) and Rogue (T33): Navigate to BODY EXTERIOR, DOORS, ROOF & VEHICLE SECURITY > DOOR & LOCK > BASIC INSPECTION > ADDITIONAL SERVICE WHEN REPLACING INTELLIGENT KEY UNIT.
- For Sentra (B18): Navigate to BODY EXTERIOR, DOORS, ROOF & VEHICLE SECURITY > DOOR & LOCK > BASIC INSPECTION > INTELLIGENT KEY UNIT > ADDITIONAL SERVICE WHEN REPLACING INTELLIGENT KEY UNIT.
Important Warnings for Technicians
Nissan emphasizes the importance of adhering to the correct procedure to prevent damage and ensure proper operation. A specific NOTICE in the bulletin warns: To prevent damage to the Intelligent Key unit, perform module configuration BEFORE NATS initialization. Failure to follow this sequence could lead to irreversible configuration issues, potentially requiring further repairs or component replacement.
This bulletin serves as a vital guide for any Nissan Intelligent Key unit service, ensuring that replacement and programming are executed flawlessly.
Bulletin Amendments
This bulletin has been revised multiple times since its original publication. Owners or technicians searching for older versions should refer to the latest update.
