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.)
