Component Description

WARNING: This page is about a different car, the 2015 Ford Fiesta. However, it is still accessible from the selected car via links, so may be relevant.

Generator

The generator is driven by the FEAD drive belt. When the engine is started, the generator begins to generate AC voltage which is converted to DC voltage by the internal voltage regulator. The DC voltage is controlled by the voltage regulator and supplied to the battery. The PCM controls the voltage regulator set point, communicating with the generator internal voltage regulator over a dedicated LIN communication circuit. The generator is equipped with a non-serviceable generator clutch pulley.

Battery Monitoring Sensor

The battery monitoring sensor is integrated with the negative battery terminal clamp and cable assembly, which provides a ground to the sensor. The battery monitoring sensor measures voltage, current, and temperature of the battery and uses these inputs to calculate the battery condition. The sensor transmits this information through a LIN circuit to the BCM. The battery monitoring sensor has a 2-pin connector providing battery voltage and LIN connections.

Powertrain Control Module (PCM)

The PCM monitors and controls the charging system.

Generator Clutch

The primary function of the generator clutch is to separate the generator rotor inertia from the FEAD belt, lowering belt tension at high Revolutions Per Minute (RPM) and reducing NVH. The generator clutch cannot be serviced separately from the generator.
