On-board diagnostic system Check engine malfunction indicator lamp Engine malfunction indicator lamp. If the "CHECK ENGINE" malfunction indicator lamp comes on when the engine is running, it indicates a malfunction of the fuel management system, emission control system, systems which impact emissions, or the fuel cap is not closed tight (check the fuel cap). If the "CHECK ENGINE" lamp is illuminated continuously and the vehicle is driving normally, you may still drive the vehicle, however, in all cases, we recommend that you have the system checked at your authorized Mercedes-Benz Center as soon as possible. CHECK ENGINE 234 If the "CHECK ENGINE" lamp comes on continuously and/or the vehicle is not driving normally, serious damage can occur to the emission system. Please contact your authorized Mercedes-Benz Center immediately. The Sequential Multiport Fuel Injection (SFI) control module monitors emission control components that either provide input signals to or receive output signals from the control module. Malfunctions resulting from interruptions or failure of any of these components are indicated by the "CHECK ENGINE" malfunction indicator lamp in the instrument cluster and are simultaneously stored in the SFI control module. If the "CHECK ENGINE" malfunction indicator lamp comes on, have the system checked at your authorized Mercedes-Benz Center as soon as possible. With some exceptions, the control module switches off the "CHECK ENGINE" malfunction indicator lamp if the condition, causing the lamp to come on, no longer exists during three consecutive cycles.
