CHECK ENGINE LIGHT [PCM (SKYACTIV-G 2.5T)]

id0102s8549100


Purpose

•  If a malfunction occurs in the engine control system, the light illuminates to warn the driver of the malfunction.

Function

•  If a malfunction occurs in the engine control system, the PCM sends a check engine light illumination request signal to the instrument cluster.
•  When the instrument cluster receives the check engine light illumination request signal sent from the PCM as a CAN signal, it turns the check engine light on.

Structure/Construction

•  The check engine light is equipped in the instrument cluster.
ac9wzn00002082
•  A warning message in the center display is displayed when the check engine light is illuminated or flashes. For the message content and verification method, refer to the CENTER DISPLAY. (See CENTER DISPLAY.)

Operation

•  The check engine light illuminates when a malfunction occurs in the engine control system, and it illuminates at the same time a DTC is recorded in the PCM.
•  The illumination conditions for the check engine light are determined by the number of drive cycles set for each DTC. For details on the drive cycle, refer to “ON-BOARD DIAGNOSTIC SYSTEM”. (See ON-BOARD DIAGNOSTIC SYSTEM [PCM (SKYACTIV-G 2.5T)].)
―  For DTCs with one drive cycle, if a malfunction is detected in the first drive cycle, the check engine light illuminates.
―  For DTCs with two drive cycles, if each malfunction is detected in the first and second drive cycles, the check engine light illuminates. However, if the same malfunction as the DTC stored in the PCM is detected, the check engine light illuminates in the first drive cycle even if the DTC is two drive cycles.
―  If the PCM detects that the engine control system is continuously normal for three drive cycles, the illuminated check engine light turns off.
•  The PCM sends a check engine light illumination request to the instrument cluster via CAN communication.
