Alternator: Description and Operation

Alternator Control

The alternator signals the ECM/PCM during charging. The ECM/PCM then controls the voltage generated at the alternator according to the electrical
load determined by the ELD (Electrical Load Detector) and driving mode. This reduces engine load to improve fuel economy.
