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.
When the alternator is at fault, one or more of the following DTC is stored.
Refer to the corresponding
troubleshooting.
