1. Understanding the NATS System and Its Components

The Nissan Anti-Theft System (NATS), also known as the Nissan Vehicle Immobilizer System (NVIS), is an anti-theft system designed to prevent unauthorized vehicle use. According to a study by the National Insurance Crime Bureau (NICB), vehicle theft costs insurers billions of dollars annually, highlighting the importance of such systems. This system comprises several key components that work together to ensure the vehicle starts only with a valid, programmed key. Understanding these components is crucial for diagnosing and addressing NATS-related issues. Let’s examine the primary parts of the NATS system:

1.1 Key Transponder

The key transponder is a small microchip embedded in the ignition key. This chip stores a unique identification code that the vehicle’s computer system recognizes.

• Function: When the key is inserted into the ignition, the transponder emits a radio frequency signal containing its unique code.
• Importance: This code must match the one stored in the vehicle’s Engine Control Unit (ECU) for the engine to start.
• Troubleshooting: Issues can arise if the transponder is damaged or the code becomes corrupted.

1.2 NATS Antenna (Immobilizer Antenna)

The NATS antenna, also known as the immobilizer antenna, is typically located around the ignition switch.

• Function: It energizes an electromagnetic field that prompts the key transponder to release its binary code. The antenna then reads this code and sends it to the Body Control Module (BCM) or directly to the ECU.
• Importance: A faulty antenna can prevent the system from reading the key’s code, leading to a no-start condition.
• Troubleshooting: The NATS antenna is often cited as a common failure point within the NATS system.

1.3 Body Control Module (BCM)

The Body Control Module (BCM) is an electronic control unit responsible for monitoring and controlling various electronic functions in the vehicle, including the NATS system.

• Function: In some NATS configurations, the antenna sends the key code to the BCM, which then validates it against the stored codes.
• Importance: The BCM acts as an intermediary, ensuring that only authorized keys are accepted.
• Troubleshooting: A malfunctioning BCM can cause various electrical issues, including problems with the NATS.

1.4 Engine Control Unit (ECU)

The Engine Control Unit (ECU) is the main computer that controls the engine’s operation.

• Function: The ECU receives the validated key code from either the NATS antenna directly or via the BCM. If the code matches, the ECU allows the engine to start by activating the fuel injection system and ignition.
• Importance: The ECU is the final authority in the starting process, ensuring that only authorized keys can start the vehicle.
• Troubleshooting: Problems with the ECU can lead to a variety of engine-related issues, including starting problems linked to the NATS.

NATS-related starting problems can be frustrating, often leaving you stranded. Recognizing the symptoms early can help you diagnose the issue and take appropriate action. Here are some common signs of a NATS problem:

2.1 Intermittent Starting Issues

One of the hallmark symptoms of a failing NATS is an intermittent no-start condition.

• Symptom: The vehicle starts normally most of the time, but occasionally, it fails to start. This issue may occur randomly, making it difficult to predict.
• Explanation: This can happen if the NATS antenna is gradually failing, leading to inconsistent communication with the key transponder.

2.2 Security Indicator Light

Most Nissan and Infiniti vehicles have a security indicator light on the instrument panel that illuminates when the NATS is active.

• Symptom: If the security light flashes or remains illuminated when the key is in the ignition, it indicates a problem with the NATS.
• Explanation: This light signals that the system is not recognizing the key, preventing the engine from starting.

2.3 Engine Cranks But Fails to Start

In many cases, a NATS problem will allow the engine to crank, but it won’t start.

• Symptom: You turn the key, and the engine turns over, but it doesn’t fire up.
• Explanation: This occurs because the NATS is preventing the fuel injection system from activating, even though the starter motor is working.

2.4 Using a Spare Key Resolves the Issue (Temporarily)

Switching to a spare key might temporarily resolve the starting problem.

• Symptom: The vehicle starts normally with the spare key, but the original key continues to cause issues.
• Explanation: This suggests that the original key’s transponder may be damaged or that the NATS is having difficulty reading its code.

2.5 No Communication with the ECU During Diagnosis

During a diagnostic scan, a mechanic may find that they cannot communicate with the ECU due to the NATS.

• Symptom: Diagnostic tools fail to establish a connection with the ECU.
• Explanation: This can occur if the NATS is blocking communication to prevent unauthorized access to the vehicle’s computer system.
