MASTER WARNING LIGHT

id092200032400


Purpose


Without TFT LCD (Type B)

•  The master warning light warns the driver that any of the following malfunctions is occurring.
―  Brake switch malfunction
―  Engine oil solenoid valve malfunction
―  Power supply system malfunction
―  Current sensor malfunction
―  Global central configuration malfunction
―  Timing chain malfunction (SKYACTIV-D 2.2)
―  Blow-by heater malfunction (SKYACTIV-D 2.2)
―  Vacuum pump malfunction (SKYACTIV-D 2.2)
―  Power brake unit malfunction (SKYACTIV-D 2.2)
―  Power brake unit vacuum sensor malfunction (SKYACTIV-D 2.2)


With TFT LCD (Type A)

•  The master warning light warns the driver that the instrument cluster has received a message from a related unit.


Function


Without TFT LCD (Type B)

•  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, current sensor error signal, power supply system error signal, global central configuration error signal, timing chain error signal (SKYACTIV-D 2.2), power brake unit error signal (SKYACTIV-D 2.2), power brake unit vacuum sensor error signal (SKYACTIV-D 2.2), and blow-by heater error signal (SKYACTIV-D 2.2) sent from the PCM
Note
•  There are warning lights which are illuminated/flashed simultaneously when the master warning light is illuminated. For the warning lights which are illuminated/flashed simultaneously when the master warning light is illuminated, refer to the ON-BOARD DIAGNOSTIC SYSTEM TEST MODE [SKYACTIV-G 2.0, SKYACTIV-G 2.5], ON-BOARD DIAGNOSTIC SYSTEM TEST MODE [SKYACTIV-D 2.2].
•  If the cancel procedure for preventing unnecessary operation of the brake override system is implemented, the PCM sends a master warning light flash request signal to the instrument cluster as a CAN signal. The instrument cluster flashes the master warning light based on the master warning light flash request signal sent from the PCM. For the cancel procedure to prevent unnecessary operation of the brake override system, refer to the DRIVE-BY-WIRE CONTROL [SKYACTIV-G 2.0, SKYACTIV-G 2.5], FUEL INJECTION AMOUNT CONTROL [SKYACTIV-D 2.2].
•  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 or a message request signal (With TFT LCD (Type A) only) from the related system.
•  The master warning light is set in the instrument cluster.
ac5wzn00002155

Operation

1.  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, or a message request signal (With TFT LCD (Type A) only) from the related unit.
2.  The instrument cluster turns the transistor on (2) intermittently for flashing and continuously for illumination based on each signal.
3.  The master warning light flashes (3) when the transistor is turned on intermittently, and it illuminates (3) when the transistor is turned on continuously.
