DESCRIPTION
The EV drive mode signal will be sent to the hybrid vehicle control ECU when the EV drive mode switch (NO. 3 combination switch assembly) is operated. If the specified conditions are met, the system enters EV drive mode and the vehicle will be driven using EV drive mode. This signal is then transmitted from the hybrid vehicle control ECU via CAN to the combination meter assembly to illuminate the EV drive mode indicator.
WIRING DIAGRAM
CAUTION / NOTICE / HINT
Depending on the condition of the hybrid control system and the driving conditions, the drive mode may not be able to be changed to EV drive mode and a warning message will be displayed on the multi-information display.
HINT:
Under the following conditions, the drive mode will not be able to be changed to EV drive mode:
PROCEDURE
1. | ASK ABOUT VEHICLE CONDITION |
(a) Check if a buzzer sounded and a message was displayed on the multi-information display when attempting to enter EV drive mode.
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 |
HINT:
If a buzzer sounds and a message is displayed on the multi-information display, one or more of the EV drive mode entry conditions have not been met.
B | END |

2. | READ VALUE USING TECHSTREAM (CAN BUS CHECK) |
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: System Select / CAN Bus Check.
CAN Bus Check Result | Proceed to |
---|---|
All of the ECUs and sensors that are currently connected to the CAN communication system are displayed | A |
None of the ECUs and sensors that are currently connected to the CAN communication system are displayed, or some of them are not displayed | B |
(e) Turn the power switch off.
B | GO TO CAN COMMUNICATION SYSTEM |
|
3. | CHECK DTC OUTPUT (HEALTH CHECK) |
(a) Connect the Techstream to the DLC3.
