Charging System Description - Overview
Depending on the vehicle condition, the variable control is not activated.
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 0.1 volt steps. In some operating
conditions, the alternator may bypass PCM control and use a default value.
When the alternator is at fault, one or more of the following DTC is stored. Refer to the corresponding troubleshooting.
DTC Detection Item
P0562 Charging System Low Voltage
P065A ACG No Charging Malfunction
P1549 Charging System High Voltage
