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


DESCRIPTION

When selecting ECO mode, the ECO mode switch (integration control and panel 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 and the hybrid vehicle control system.
