No, the light does not go out. You can make it turn off by pressing the button on the left stalk but if you press it again, it will say "you have 2 messages". Press again and it will say, "Engine System Service Required". The second message is about servicing the airbag system. Anyway, the message is always there waiting if you press the button to view it.
Thanks for your response but I'm still a bit confused. The "Engine System Service Required" message is still lit in the window and the whole goal of this is to clear that message so it doesn't keep showing every time you start the car. I saw the same window display "44" and assumed it was a code explaining why the message is lit. Apparently "44" has nothing to do with why the message is lit so why is it coming on each time the car is turned on, even though there are no codes stored (for OBDII) and no "check engine" light? When the Volvo dealer's mechanic sees this message come on, he or she must have some way to determine why it is lit. I apologize if the wording of my original question wasn't clear enough. I hope I've been able to explain better.
It appears that you have not been reading what I have been writing. Your answer tells me that you did not pay attention to anything I've said. The message that is displayed is, "Engine System Service Required" and NOT Emissions System Service Required. The "Check Engine" light is NOT on. As I've already stated TWICE previously, there are NO DTC's stored or pending. I do NOT need to know how to reset the service indicator light; it is not lit. I do NOT need a code reader because I already own one.
I'm simply trying to figure out why the "Engine System Service Required" message is showing in the information window on the left side of the instrument panel and how to permanently clear it once the problem (if there is one) is fixed.
If you worked at a Volvo dealer and I brought my car in and said, "the Engine System Service Required message is showing in my information display, would you please see what the problem is, correct that problem, and make the light go out." Please describe the procedure you would follow in this scenario.
ok if you dont fault code that light is for check engine light now there is at times prolbem in computer to turn the light on so you have only that messege try this but you will need a scan tool to reset the light when check engine light comes or any fault code by scan tool unplug any sensor from engine the best is unplug the mass air flow sensor and let the car run let computer pick up the fault code erase the fault with a scan tool and now you light should be off ,when the key is on position 2 do you see light check engine light coming on for little time ?
also try this i know is not the light you having but you will send a signal to reset signal to ecu there is something frozen in ecu were is not telling right info or fault code
