Taiwan

Purpose

•  The check fuel cap warning light/check fuel cap warning indication warns the driver that the fuel cap may not have been closed securely.

Function

•  When the PCM stores DTC P0457:00 (PCM detects that fuel cap is open), it sends a check fuel cap warning light illumination request signal/check fuel cap warning indication request signal to the instrument cluster. For details on the illumination conditions, refer to [ON-BOARD DIAGNOSTIC SYSTEM]. (See ON-BOARD DIAGNOSTIC SYSTEM [PCM (SKYACTIV-G 2.5T)].)

•  Based on the check fuel cap warning light illumination request signal/check fuel cap warning indication request signal sent from the PCM via CAN communication, the instrument cluster turns the check fuel cap warning light on.

Construction

•  The check fuel cap warning indication is displayed in the multi-information display. (With multi-information display)

•  The check fuel cap warning light is built into the instrument cluster.

•  For vehicles equipped with the center display, a warning message is displayed in the center display as the same time the check fuel cap warning light is turned on/check fuel cap warning indication is displayed. For the message content and verification method, refer to [CENTER DISPLAY]. (See CENTER DISPLAY.)

Operation

Check fuel cap warning light

1.  When the ignition is switched ON (engine off or on), the instrument cluster receives (1) an check fuel cap warning light illumination request signal from the PCM via CAN communication.

2.  The instrument cluster turns the transistor on (2) based on the check fuel cap warning light illumination request signal.

3.  When the transistor turns on, a ground circuit with the check fuel cap warning light is established and the check fuel cap warning light turns on (3).
