well i know my focus service engine light was on and we just unhooked the battery for 20 seconds and now the light is off and it has been 1 month
Take a look here askville.amazon.com/service-engine-light-wrong-saturn-Vue-2003/AnswerViewer.do?requestId=3645084
It means that the engine computer has detected an emissions related failure.
How Do I reset the Engine service light on a 1996 Inifiniti I30? Please help. thanks
The service engine soon, or check engine, light is reset with a scan tool after repairing the cause of the trouble codes.
the computer tells it to glow.
you should have your engine checked out to make sure everything is working well
remove the battery cable for 1 min
YES IT CAN SO GET IT FIXED
Have vehicle scanned to have codes cleared
Another way to disable the service engine soon light is to disconnect the battery for about 10-20 minutes.The most common reason for the service engine soon light to come on is that the gas cap wasn't tightened all the way.
