HYBRID CONTROL SYSTEM Pattern Select Switch EV Mode Circuit

DESCRIPTION

The EV drive mode signal is sent to the power management control ECU. 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 when attempting to enter EV drive mode.

      Result
      Result Proceed to
      No buzzer sounded. A
      A buzzer sounded. B

      Tech Tips

      If a buzzer sounds, 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).
