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


DESCRIPTION

The EV mode switch signal will be sent to the hybrid vehicle control ECU when the EV mode switch is operated. If the specified conditions are met, the system enters EV drive mode and the vehicle will be driven using EV drive mode. This signal is then transmitted from the hybrid vehicle control ECU via CAN to the combination meter assembly to illuminate the EV drive mode indicator.

CAUTION / NOTICE / HINT

Depending on the condition of the hybrid control system and the driving conditions, the drive mode may not be able to be changed to EV drive mode and a warning message will be displayed on the multi-information display.

HINT:

Under the following principal conditions, the drive mode will not be able to be changed to EV drive mode:

·

The hybrid control system is extremely hot.

·

The hybrid control system is extremely cold.

·

The engine is warming up.

·

The SOC (State of Charge) of the HV battery is low.

·

The vehicle is being driven at a speed higher than the specified value.

·

The accelerator pedal is being fully depressed or the vehicle is climbing a slope.

·

The defroster is on.

·

DTCs are stored.
