Honda HR-V: Description
CHARGING SYSTEM DESCRIPTION - OVERVIEW
Overview
The PCM gathers vehicle operating system data and determines the required charging rate. Based on that data, the PCM commands the alternator to provide a specific charging rate (voltage) between 12.5 and 14.5 volts, using 1/10th volt steps. In some operating conditions, the alternator may bypass PCM control and use a default value.
*Depending on the vehicle condition, the variable control is not activated.
