POWER CUT OFF CONTROL
POWER CUT OFF CONTROL : System Description
INFOID:0000000010120567
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.

CHARGE PORT CONTROL
CHARGE PORT CONTROL : System Description
INFOID:0000000010120568
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

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.

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
.
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)
Lock mode
FUNCTION DESCRIPTION
LOCK mode
Automatically locks when the normal charge connector is connected.
AUTO mode
Locks only during normal charging. (Unlocks automatically when charging is completed.)

• 5 seconds pass after charge connector lock operation.
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
• Charge port lid opener switch or charge port lid opener button: ON

Control Outline
When the charge port lid opener switch signal is received 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 transmits the charge sound request signal to the VSP
control unit. When the VSP control unit receives the signal, it operates the VSP speaker and sounds the
charge port lid unlock sound/normal charge connector unlock sound. The VCM also turns ON the charging
status indicator.
