There's no way to know what the light means without running a diagnostic scan on the system to determine the nature of the fault.As a rule, a continuous Check Engine light usually signals a "hard fault" or failure that has occurred. If the light comes on and off, or only blinks momentarily, the problem may be minor or intermittent in nature.To help identify the problem, please consult our service engineer @ 03-41069395 or drop by at our service centre @ No 1 & 3, Jalan 3/4C, Desa Melawati,, 53100 Kuala Lumpur. Because we know what is the best for your car !!
