HYBRID CONTROL SYSTEM Pattern Select Switch EV Mode Circuit

DESCRIPTION

The EV drive mode signal will be sent to the power management 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 power management control ECU via CAN to the combination meter assembly to illuminate the EV mode indicator light.

PROCEDURE


  1. ASK ABOUT VEHICLE CONDITION


    1. Check if a buzzer sounded and a message was displayed on the multi-information display when attempting to enter EV drive mode.

      Result
      Result Proceed to
      No buzzer sounded and no message was displayed on multi-information display. A
      A buzzer sounded and a message was displayed on multi-information display. B

      Tech Tips

      If a buzzer sounds and a message is displayed on multi-information display, one or more of the EV drive mode entry conditions have not been met. Check that all of the EV drive mode entry conditions have been met before pressing the EV drive mode switch (pattern select switch assembly).
