SIGNAL PATH

When Brake Fluid Is Insufficient:

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

fluid level switch.

When Operating The Parking Brake:

The combination meter turns ON/OFF the brake warning lamp, according to the ON/OFF state of the parking

brake 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
