Component Description

Generator

The generator is equipped with an electronic internal voltage regulator.

Battery Monitoring Sensor

NOTE: Unless the battery is being replaced, DO NOT reset the battery monitoring system using the diagnostic scan tool. This reset is reserved for new battery installation only. This reset will clear the learned battery data, the battery time in service, and will affect the aging algorithm parameters, which have been learned since the installation of the battery.

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 the LIN circuit to the BCM. The battery monitoring sensor has a 2-pin connector providing battery voltage and LIN connections.

The battery monitoring sensor is an input to the Electrical Energy Management software. If the sensor malfunctions due to wiring issues or failure, a DTC sets. In most cases the Electrical Energy Management functions are turned off until the sensor operation is restored.

Powertrain Control Module (PCM)

The PCM monitors and controls the charging system.
