EV Drive Mode Switch Circuit

L110F HYBRID VEHICLE CONTROL: HYBRID CONTROL SYSTEM: EV Drive Mode Switch Circuit
- EV Drive Mode Switch Circuit

DESCRIPTION

The EV mode switch is built into the outer mirror switch assembly. EV mode switch signals are sent to the hybrid vehicle control ECU via CAN communication. If EV mode switch signals are input to the hybrid vehicle control ECU, the ECU sends signals to the combination meter assembly via CAN communication to turn on the EV mode light.





If any of the following conditions are not met, EV mode may not be turned on or the mode may be canceled. (A buzzer sounds to indicate that the transition to EV mode is canceled and a message is displayed on the multi-information display.)





INSPECTION PROCEDURE

PROCEDURE

1. ASK CUSTOMER ABOUT VEHICLE CONDITION

(a) Ask the customer if a buzzer sounded to indicate that the transition to EV mode was canceled and a message was displayed on the multi-information display when he or she pressed the EV mode switch.

Result:
