HYBRID CONTROL SYSTEM Pattern Select Switch EV City Mode Circuit

DESCRIPTION

When a sufficient amount of electricity for EV driving is remaining in the HV battery, the operation mode can be switched to EV City mode.

EV City mode limits motor output and minimizes the operation of the gasoline engine. Therefore, the vehicle can be driven with only electric motor in city areas, etc.

When in EV City mode, the "EV CITY" indicator illuminates.

PROCEDURE


  1. ASK ABOUT VEHICLE CONDITION


    1. Check if a buzzer sounded and a message was displayed on the multi-information display when operating the EV City mode switch (pattern select switch assembly).

      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 the multi-information display, the EV City mode entry conditions have not been met.
