The EV drive mode signal will be sent to the hybrid vehicle control ECU when the EV drive mode switch (pattern select switch assembly) 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.
