Fuel Economy Mode

The generator battery control module will enter Fuel Economy Mode when all of the following conditions are true:

• Estimated ambient air temperature is equal to or greater than 0°C (32°F).
• The calculated battery current is less than 15 amperes and greater than - 8 amperes.
• The battery state of charge is greater than or equal to 80 percent.
• The rear defoggers are turned OFF.
• The electric cooling fans are on low speed or OFF.

The targeted generator output voltage is 13 volts. The generator battery control module will exit this mode once the criteria are met for Charge Mode or it will boost voltage to a pre-determined set point for the fuel pump, headlamps, or windshield wipers.
