The combination meter turns ON/OFF the brake warning lamp, according to the ON/OFF state of the brake
fluid level switch.

When The EBD Function Is In Abnormal State

• The ABS actuator and electric unit (control unit) transmits a brake warning lamp signal to the combination

meter via CAN communication when detecting a malfunction in the EBD function.

• The combination meter turns ON the brake warning lamp when receiving a brake warning lamp signal.
• For the relationship between warning lamp and DTC, refer to 

BRC-84, "DTC Index"

.

When The Brake Vacuum Sensor System Is In Abnormal State

• The ABS actuator and electric unit (control unit) transmits a brake warning lamp signal to the combination

meter via CAN communication when detecting a malfunction in the brake vacuum sensor system.

• The combination meter turns ON the brake warning lamp when receiving a brake warning lamp signal.
• For the relationship between warning lamp and DTC, refer to 

BRC-84, "DTC Index"

.

LIGHTING CONDITION

When any of the condition listed below is satisfied while the engine is running:
• Brake fluid level switch ON.
• A malfunction is detected in the EBD function of the ABS actuator and electric unit (control unit).
• A malfunction is detected in the brake vacuum sensor system.
• For the relationship between warning lamp and DTC, refer to 

BRC-84, "DTC Index"

.

SHUTOFF CONDITION

• When the condition listed below is satisfied while the ignition switch ON:
- Brake fluid level switch is OFF.
- When EBD function of the ABS actuator and electric unit (control unit) is normal.
