Purpose
The master warning light warns the driver that any of the following malfunctions is occurring.
Brake switch malfunction
Engine oil solenoid valve malfunction
Automatic configuration malfunction
Function
The instrument cluster illuminates the master warning light based on the following CAN signals:
Brake switch No.1 error signal, brake switch No.2 error signal, engine oil solenoid valve error signal, and automatic configuration error signal sent from the PCM
The instrument cluster flashes the master warning light based on the master warning light flash request signal sent from the PCM as a CAN signal.
The master warning light flashing pattern is as indicated in the figure.

Construction
The instrument cluster microcomputer controls the illumination/flashing/turning off of the master warning light based on each error signal sent from the PCM.
The master warning light is set in the instrument cluster.

Operation
When the ignition is switched ON (engine off or on), the instrument cluster receives (1) each error signal or a master warning light flash request signal from the PCM.
The instrument cluster turns the transistor on (2) intermittently for flashing and continuously for illumination based on each signal.
The master warning light flashes (3) when the transistor is turned on intermittently, and it illuminates (3) when the transistor is turned on continuously.

Fail-safe
Function not equipped.
