Warning Lamps and Indicator Lamps

HPCM controls the following warning lamps and indicator lamps that are located on the combination meter.

READY TO DRIVE INDICATOR LAMP






The READY to drive indicator lamp indicates that the vehicle is in a state allowing vehicle travel. HPCM transmits the READY to drive indicator lamp 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.





*: The READY to drive indicator lamp blinks when charging resistor protection activates. (Turn the ignition switch OFF and wait for at least 1 minute, then turn the switch to READY again.)

HYBRID SYSTEM WARNING LAMP






The hybrid system warning lamp turns ON when a malfunction occurs in the hybrid system.
When HPCM either detects a malfunction or receives a warning lamp activation request signal from a control module, it transmits the hybrid system warning lamp activation signal to the combination meter via CAN communication.
The hybrid system warning lamp operates as follows.





*: When the system recovers from the malfunction and the ignition switch is turned from OFF to ON 2 times, the hybrid system warning lamp turns OFF.

12-VOLT BATTERY CHARGE WARNING LAMP






The 12-volt battery charge warning lamp turns ON when a malfunction occurs in the DC/DC converter.
When it detects a DC/DC converter malfunction, HPCM transmits the 12-volt battery charge warning lamp signal to the combination meter via CAN communication to turn the lamp ON.
The 12-volt battery charge warning lamp operates as follows.






OIL PRESSURE WARNING LAMP






The oil pressure warning lamp turns ON when a malfunction is detected in the engine hydraulic system.
When it detects an engine hydraulic system malfunction, HPCM
transmits the oil pressure warning lamp signal to the combination meter via CAN communication to turn the lamp ON.
The oil pressure warning lamp operates as follows.






EV INDICATOR LAMP






This lamp turns ON when the vehicle is driving using only the traction motor to inform the driving that motor driving mode is in effect.
HPCM transmits the EV indicator lamp signal to the combination meter via CAN communication.
The EV indicator lamp operates as follows.






ECO DRIVE INDICATOR LAMP






Turns ON when ECO mode is selected with the drive mode selector.
When ECO mode is selected, the ECO mode signal is transmitted from TCM to HPCM via CAN communication. When HPCM receives the signal, it transmits the ECO drive indicator control signal to the combination meter via CAN communication.
The ECO drive indicator lamp operates as follows.






ASSIST CHARGE GAUGE

Indicates the status of the traction motor.





HPCM transmits the traction motor state as the assist charge signal to the combination meter via CAN communication.
The assist charge gauge operates as follows.
