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 drive mode, the ECO mode switch (integration control and panel sub-assembly) operation signal is sent to the air conditioning amplifier assembly. Following this, ECO drive mode control is activated for the heater and air conditioning system.
