SEC-222 < FUNCTION DIAGNOSIS > [SEDAN WITH INTELLIGENT KEY] NVIS (NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS) • Possible symptom of NVIS (NATS) malfunction is “Engine cannot start”. In L32, the engine can be started with the Intelligent Key system and NVIS (NATS). Identify the possible causes according to “Work Flow”, • If ECM other than Genuine NISSAN is installed, the engine cannot be started. For ECM replacement proce- dure, refer to SEC-214, "ECM RE-COMMUNICATING FUNCTION : Special Repair Requirement" PRECAUTIONS FOR KEY REGISTRATION • The key registration is a procedure that erases the current NVIS (NATS) ID once, and then re-registers a new ID operation. Therefore the registered Intelligent Key is necessary for this procedure. Before starting the registration operation collect all registered Intelligent Keys from the customer • When registering the Intelligent Key, performs only one procedure to register simultaneously both ID (NVIS “NATS” ID registration and Intelligent Key ID registration). The NVIS (NATS) ID registration is the procedure that registers the ID stored into the transponder (inte- grated in intelligent key) to BCM. The Intelligent key ID registration is the procedure that registers the ID to BCM. • When performing the Intelligent Key system registration only, the engine cannot be started by inserting the key into the key slot. When performing the NVIS (NATS) registration only, the engine cannot be started by the operation when carrying the key. The registrations of both systems should be performed. SECURITY INDICATOR • Warns that the vehicle is equipped with NVIS (NATS). • The security indicator always blinks when the Intelligent Key is removed from the key slot and when the igni- tion switch is in LOCK position. NOTE: Because security indicator is highly efficient, the battery is barely affected. |
