SYNCHRONIZATION WITH WARNING LAMP/INDICATOR LAMP

Not applicable

SYNCHRONIZATION WITH WARNING/INDICATOR (INFORMATION DISPLAY)

Synchronization is applied.

For information display, refer to 

EVC-36, "WARNING/INDICATOR (ON INFORMATION DISPLAY) : Shift P

Warning"

.

SYSTEM DIAGRAM

SIGNAL PATH

• The electric shift selector sends shift position information to VCM.

• BCM transmits a door switch signal to VCM.

• VCM judges the vehicle condition according to shift position information and a door switch signal. VCM

transmits a shift P range request display signal to the combination meter if the driver's door is opened with

the shift position not in P position.

WARNING OPERATING CONDITION

When all of the following conditions are satisfied:

• Shift position: Except P range

• Front door (driver side): Open

WARNING CANCEL CONDITION

The indication is cancelled when any of the following conditions are satisfied:

• The shift position is changed to P position.

• The driver’s door is closed.

ELECTRIC POWER TRAIN SYSTEM
ELECTRIC POWER TRAIN SYSTEM : System Description

INFOID:0000000010120553

CONTROL OUTLINE

EV requires electric power for the operation of all its systems.

The power stored in the Li-ion battery is supplied as high-voltage direct current to the high-voltage system

while also being converted to 13-15 V by the DC/DC converter and supplied to the 12 V power system. 

VCM judges the vehicle status from various information and performs various EV system controls in a compre-

hensive manner.
