Have vehicle scanned to determine the problem
When service engine light is on on a 2003 Chevy Trailblazer, the problem could be a faulty thermostat, a circuit range performance problem, or any other problem.
Indicative of problem with engine emission system
NO, the service engine light means that a scheduled service is due. Usuallly this means an oil/filter change. However if the Check Engine light is on this can be serious, and means there is a problem with the emissions controls.
what does the engine light on the 1999 olds alero mean
A reset Engine Service Light comes on when an issue comes up with in the engine. This light can be reset by a tech or by fixing the problem.
What model do you have? I am saying no to your question. In most vehicles the service engine light deals with the operation of the "engine", igniton system, exhaust, and fuel system. If there is a problem with the brakes you could see an ABS light (if equiped) or a BRAKE! light on. If the Service engine soon light is on in your vehicle the problem lies in one of those systems. Good Luck
The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.
