I have a 2016 Honda Civic EX-T with only 29000 miles on it. I had the oil changed at the dealership about 3 weeks ago and no issues. I decided to sell the car and get a truck, since my wife also has a 2017 Honda Civic. A potential buyer brought a dealership scanner to scan any codes on the vehicle. After he scanned the car, he asked to drive it. We went for a drive and all systems were displaying on the dash as issues. We got back to the house and he said he would use his scanner to clear the codes and proceeded to do so. After he left, the dash showed the TMPS light, as well as the vehicle stability light. Now, anytime I start the vehicle, it shows all systems as having issues. I had no warning lights or system issues before he put his scanner on the car. Any ideas why this is happening and how do I clear this? Thank you for any assistance you can provide.
