Is there a way to turn off Service Engine Light and Maint Req'd lights manually?

[BullShifter]

Service engine - no resetting without out pulling codes is worthless anyway.
maint req'd - yes

As covered 10 billion times already here it goes again

With the engine off
Press & hold the trip reset button with left hand
With right hand switch ignition on - do not start
Wait for light to go off - your done
