Charging System

WARNING: This page is about a different car, the 2005 Mercury Sable and 2005 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.

The PCM constantly monitors the generator regulator output. When the PCM detects a continuous high or low output signal, or when the ignition is ON and the engine is OFF, the PCM sends a CAN message to the instrument cluster to turn the charging system warning indicator on. When the ignition is ON with the engine running and the PCM determines that the set point for the regulator has been met, the PCM will send a CAN message to the instrument cluster to turn the charging system warning indicator off.
