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.
