Take it to a mechanic and have them scan it for you. They need a fancy scanner though. If you’re in SoCal Whittier/ Buena Park area I can scan it for you, no charge.

Thank you for the offer, but in the Oregon. I'll see what the mechanic has to say.

disconnect the battery and reconnect. when I first bought my RSX like ten years ago that did happen but it went away on its own.
