Pattern Select Switch ECO Mode Circuit

HYBRID / BATTERY CONTROL: HYBRID CONTROL SYSTEM: Pattern Select Switch Eco Mode Circuit
- Pattern Select Switch Eco Mode Circuit

DESCRIPTION

When selecting ECO mode, the ECO mode switch (eco switch assembly) operation signal is sent to the air conditioning amplifier assembly. Following this, ECO mode control is activated for the heater and air conditioning system.
