HYBRID CONTROL SYSTEM Pattern Select Switch EV City Mode Circuit

DESCRIPTION

The EV city mode signal will be sent to the ECM when the EV city mode switch (integration control and panel sub-assembly) is operated. If the specified conditions are met, the system enters EV city mode and the vehicle will be driven using EV city mode. This signal is then transmitted from the ECM via CAN to the combination meter assembly to illuminate the EV city 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 city 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 city mode entry conditions have not been met. Check that all of the EV city mode entry conditions have been met before pressing the EV city mode switch (integration control and panel sub-assembly).
