Title: HYBRID / BATTERY CONTROL: HYBRID CONTROL SYSTEM (for 2WD with NICKEL METAL HYDRIDE BATTERY): Pattern Select Switch Eco Mode Circuit; 2019 - 2020 MY RAV4 HV [11/2018 - 08/2020]

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.
