COMPONENT PARTS

Warning/Indicator Lamp

VCM controls the following warning lamps and indicator lamps.

READY TO DRIVE INDICATOR LAMP






The READY to drive indicator lamp indicates that the vehicle is in a state allowing vehicle travel. VCM transmits a READY to drive indicator lamp request signal to the combination meter via CAN communication to turn ON the READY to drive indicator lamp.
The READY to drive indicator lamp operates as follows.






EV SYSTEM WARNING LAMP






The EV system warning lamp turns ON if a malfunction occurs with the EV system.
If VCM detects a malfunction or receives an EV system warning lamp request signal from any other ECUs, VCM transmits an EV system warning lamp request signal to the combination meter via CAN
communication.
The EV system warning lamp operates as follows.






POWER LIMITATION INDICATOR LAMP






The output limit indicator turns ON when the traction motor output is limited.
When the traction motor output is limited, VCM sends an output limit indicator ON request signal to the combination meter via CAN communication.
The power limitation indicator lamp operates as follows.





For output limit conditions, refer to "MOTOR POWER CONTROL : System Description" System Description.

LOW BATTERY CHARGE WARNING LAMP






The low battery charge warning lamp turns ON when the Li-ion battery remaining energy is lowered. When VCM detects that Li-ion battery remaining energy is approximately 4kWh or less, VCM transmits a low battery charge warning lamp request signal to the combination meter via CAN communication.
The low battery charge warning lamp operates as follows.






PLUG IN INDICATOR LAMP






The plug in indicator lamp turns ON when a charge connector is connected to the normal charge port or the quick charge port. VCM supplies power to the plug in indicator lamp in the combination meter to turn on the lamp when VCM receives the EVSE connecting signal or the quick charger connecting signal from the on-board charger.
The plug in indicator lamp operates as follows.





NOTE:
When EVSE is connected, the indicator lamp turns ON immediately. The indicator lamp turns OFF after the 10
seconds passes in non-operating state.

12V BATTERY CHARGE WARNING LAMP






When DC/DC converter is malfunctioning, the 12V battery charge warning lamp turns ON.
NOTE:
- If the 12V battery voltage lowers during READY, the READY state is also cancelled.
- If VCM judges that the vehicle is running (transmission in a position except P range and parking brake released) when the 12V
battery voltage lowers, it turns ON the 12V battery charge warning lamp and alerts the driver by sounding a buzzer.
The 12V battery charge warning lamp operates as follows.
