Nissan Murano: System / Throttle Control
SYSTEM DIAGRAM
*: ECM determines the start signal status by the signals of engine speed and battery voltage.
SYSTEM DESCRIPTION
ECM calculates the value of signal transmitted from the accelerator pedal and activates the throttle valve by transmitting a control signal to the electric throttle control actuator. This allows the optimum throttle angle and improves drivability and fuel consumption. In addition, ECM learns the fully closed position every time when the ignition switch is turned OFF to improve the accuracy in throttle valve position.
When a malfunction occurs in the throttle control system, the throttle valve is closed by the return spring and maintains the minimum engine speed by holding a slightly opened condition which is close to the fully opened condition. This allows the securing of brake system, power steering system, and electric system and the ensuring of the safety.

Autolight system
The autolight system allows the headlights to turn on and off automatically. The autolight system can:
Turn on the headlights, front parking, tail, license plate and instrument panel lights automatically when it is dark. Turn off all the lights (except daylight running lights) when it is light. Keep all the lights on for a period of time after you place the ignition switch in the OFF position and all doors are closed.
