SYSTEM DIAGRAM

DESCRIPTION

Because EV uses high voltage power, there is a risk of electric shock if the high voltage circuit is shorted to a

body ground during a collision. To avoid such risks, if VCM detects a car crush information signal, VCM deac-

tivates the system main relay to cut off the Li-ion battery from the high voltage circuit so that the risk of electric

shock is reduced.

When detecting a serious collision

When receiving a car crash information signal from the air bag diagnosis sensor unit, VCM turns OFF the sys-

tem main relay and quickly interrupts the high voltage circuit. In addition, VCM detects DTC P3137 and prohib-

its the READY operation until the DTC is erased.

NOTE:

The collision detection level of VCM may differ from an actual vehicle damage state.

When detection a minor collision

When receiving a light crash judgment signal from the air bag diagnosis sensor unit, VCM turns OFF the sys-

tem main relay and quickly interrupts the high voltage circuit. The READY operation becomes possible after a

lapse of 90 seconds or more (VCM performs self shutoff) after the power switch is turned OFF.

CAUTION:

When bringing VCM into self shut off, never perform vehicle handling such as opening and closing of

doors while the power switch is OFF. If some kind of vehicle handling is performed, then wait another

90 seconds or more from the time of the vehicle handling.

NOTE:

• The collision detection level of VCM may differ from an actual vehicle damage state.

• When a collision occurs more than once during the same trip (no history of turning OFF the power switch),

VCM judges “detection of serious collision” and prohibits the READY operation.

SYSTEM DIAGRAM

SYSTEM DESCRIPTION

The following charge port controls related to charging are performed comprehensively by the VCM according

to the vehicle conditions and signals from the switches.

• Charge connector lock/unlock control

• Charge port light control

• Charge port lid open control

• Answer-back control

CHARGE CONNECTOR LOCK/UNLOCK CONTROL

Control Outline

The VCM judges the lock operation conditions according to the mode signal from the charge connector lock

switch, and the EVSE connection signal received from the PDM (Power Delivery Module) via CAN communi-

cation. If the conditions are met, VCM turns ON the charge connector lock actuator relay and operates the

charge connector lock actuator in the close direction to lock the normal charge connector.

When the charge port lid opener switch signal from the charge port lid opener switch is received, or when the

charge port lid open request signal for the charge port lid opener button is received from the BCM via CAN

communication. If normal charging is stopped and other unlock conditions are met, the VCM turns ON the

operation.

CAUTION:

When bringing VCM into self shut 

off, never perform vehicle handling 

such as opening and closing of 

doors while the power switch is 

OFF. If some kind of vehicle han-

dling is performed, then wait an-

other 90 seconds or more from the 

time of the vehicle handling.

SYSTEM

charge connector lock actuator relay and operates the charge connector lock actuator in the open direction to

unlock the normal charge connector.

The lock modes are as per the following.

NOTE:

For details of the functions in each mode and the actuator operations, refer to 

VC-19, "CHARGE PORT CON-

TROL : System Description"

.

Lock Operating Conditions

When all of the following conditions are met, the VCM locks the charge connector.

LOCK mode

• Charge connector lock switch: LOCK mode

• Shift position: P

• Normal charge connector: Connected (fully engaged)

AUTO mode

• Charge connector lock switch: AUTO mode

• Shift position: P

• Normal charge connector: Connected (fully engaged)

• Normal charge start

CAUTION:

Does not lock when only automatic charging of the 12V battery is operating.

Unlock Conditions

When any of the following conditions is met, the VCM releases the lock of the charge connector.

LOCK mode

• Charge port lid opener switch or charge port lid opener button is ON.

• Charge connector lock switch is moved to the neutral position (UNLOCK mode).

• Shift position is any position other than P position.

• Vehicle READY state is engaged.

AUTO mode

• Charge port lid opener switch or charge port lid opener button is ON.

• Charge connector lock switch is moved to the neutral position (UNLOCK mode).

• Shift position is any position other than P position.

• Vehicle READY state is engaged.

• Normal charging stops.

CAUTION:

After the charge port lid opener switch or charge port lid opener button is ON, the charge connector is

automatically locked again after 30 seconds if it is not disconnected.

CHARGE PORT LIGHT CONTROL

Control Outline

When the charge port lid opener switch signal is input from the charge port lid opener switch, or the charge

port lid open request signal for the charge port lid opener button is received from the BCM via CAN communi-

cation, then based on charge connector connected/disconnected and other vehicle conditions, the VCM out-

puts power supply to the charge port light to turn it ON. 

For details of the function, refer to 

VC-19, "CHARGE PORT CONTROL : System Description"

.

ON Conditions

When all of the following conditions are met, the VCM turns ON the charge port light.

• Vehicle state: Other than READY

• Shift position: P position

• Any of the following conditions is met.

- Charge port lid opener switch or charge port lid opener button: ON

- Normal or quick charge connector: Disconnected (removed)

CHARGE PORT LID OPEN CONTROL

Control Outline

When the charge port lid opener switch signal is input from the charge port lid opener switch, or the charge

port open request signal for the charge port lid opener button is received from the BCM via CAN communica-

tion, then according to the vehicle conditions, the VCM operates the charge port lid actuator to unlock the

charge port lid.

Charge Port Lid Unlock Conditions

When all of the following conditions are met, the VCM unlocks the charge port lid.

• Shift position: P position

• Vehicle state: Other than READY
