Check Engine Lamp:

The check engine lamp, located on the left side of the instrument cluster, illuminates to inform the driver of a malfunction in the ECU's calculation function. It can also be used by the technician to identify trouble codes stored in the E.C.U.

It will also come on to warn the driver when a malfunction occurs that will affect the emission control system performance. Malfunctions related to emission system performance can be detected by performing MODE 3 (STORED CODES) TEST.
The lamp also flashes simultaneously with the red diode on the ECU when extracting codes or when inspecting feedback operation.
