Component Description

Battery Current Sensor 

The battery current sensor is attached to the negative battery cable. It is supplied a 5-volt reference voltage and a ground from the BCM. The battery current sensor is a Hall-effect sensor that supplies a PWM feedback signal to the BCM. This sensor serves as input to the Electrical Energy Management software. If the sensor malfunctions due to wiring issues or failure a DTC will be set. In most cases the Electrical Energy Management functions are turned off until the sensor operation is restored.

Generator 

The generator is equipped with an electronic internal voltage regulator and is driven by the FEAD belt.

Generator Clutch 

Vehicles with the 2.0L EcoSport engine are equipped with a generator clutch pulley that is serviced separately from the generator. The primary function is to separate the generator rotor inertia from the FEAD belt, lowering belt tension at high Revolutions Per Minute (RPM) and reducing NVH.

Generator Current Sensor 

The generator current sensor is attached to the generator B+ cable. It is supplied a 5-volt reference voltage and a ground from the PCM. The generator current sensor is a Hall-effect sensor that supplies an analog feedback signal to the PCM.

Powertrain Control Module (PCM) 

The PCM monitors and controls the charging system. For more information, Refer to: Electronic Engine Controls - System Operation and Component Description 2.0L EcoBoost . (with 2.0L EcoSport), or Refer to: ELECTRONIC ENGINE CONTROLS - SYSTEM OPERATION AND COMPONENT DESCRIPTION 3.0L EcoBoost
