SIGNAL PATH

• The traction motor inverter transmits a motor torque limit signal to VCM when the traction motor needs to be

protected.

• LBC transmits a motor torque limit signal to VCM when Li-ion battery cannot output power normally.

• When receiving a motor torque limit signal from the traction motor inverter or LBC, VCM transmits a power

limitation indicator lamp request signal to the combination meter.

• The combination meter turns ON the power limitation indicator lamp according to the signal.

LIGHTING CONDITION

For lighting condition, refer to 

EVC-48, "MOTOR POWER CONTROL : System Description"

.

SHUTOFF CONDITION

The traction motor or Li-ion battery returns from the output limiting state.

SYSTEM DIAGRAM

SIGNAL PATH

• BCM transmits a READY signal to VCM when the driver operates the power switch to READY.

• The high voltage circuit is connected when VCM receives a READY signal. When the high voltage circuit is

connected normally, LBC and the traction motor inverter transmit a high voltage discharge permit signal to

VCM.

• When receiving a high voltage discharge permit signal, VCM judges that the vehicle is in a drivable condition

and transmits a READY to drive indicator lamp request signal to the combination meter for turning ON the

READY to drive indicator lamp.

LIGHTING CONDITION

• Vehicle: READY state.

SHUTOFF CONDITION

• Power switch: OFF

• When a malfunction occurs in EV system.

BLINKING CONDITION

• When operating from power switch ON to READY
