Check your battery wires Arnie. Make sure the terminals and post are cleaned good. Make sure the ends are tight. Clamp them down to your wire endings real tight. Sometimes they come loose. The light might need taken off with a computer scan. But, it might be on because you have a bad connection. Check the wires real good. I am sure that is the problem Arnie. 4 thumbs up is greatly appreciated if you appreciate the reply. Arnie, don't hesitate to ask me a question. I am here to help you. Thanks for choosing FixYa and have a great evening Arnie. Thanks.

p1650 and p 1651 are quad driver module codes the quad driver controls 4 outputs hence the name quad they are the1 cooling fan circuit
2 a/c clutch
3ses light(service engine soon)
4and shift light

if any of these issuses are malfunctioning they will set the codes you are talking about, the sneaky thing is that if the ses bulb is bad in the instrument cluster it will set the code as well. hope this helps
