17.

BCM (Body Control Module)

BCM controls INTELLIGENT KEY SYSTEM (ENGINE START FUNCTION), INFINITI VEHICLE IMMOBILIZER SYSTEM-NATS [IVIS (NATS)] and VEHICLE SECURITY SYSTEM.

BCM performs the ID verification between BCM and Intelligent Key when the Intelligent Key is carried into the detection area of inside key antenna, and push-button ignition switch is pressed. If the ID verification result is OK, ignition switch operation is available.

Then, when the ignition switch is placed in the ON position, BCM performs ID verification between BCM and ECM. If the ID verification result is OK, ECM can start engine.

Refer to Component Location for detailed component location.

18.

Combination meter

Combination meter transmits the vehicle speed signal to BCM via CAN communication.

BCM also receives the vehicle speed signal from ABS actuator and electric unit (control unit) via CAN communication. BCM compares both signals to detect the vehicle speed.

Security indicator lamp is located on combination meter.

Security indicator lamp blinks when ignition switch is in any position other than ON to warn that INFINITI VEHICLE IMMOBILIZER SYSTEM-NATS [IVIS (NATS)] is on board.
