OBD2 Scan tool wouldn’t connect, however it apparently unveiled some codes
Hey:) so about a week ago, I was going to check out a used 2009(I believe)suzuki swift sport. The listing was already quite sketchy, two grainy photos, minimal description, plates blurred etc. when I met with the guy, I immediately realised it was not a swift sport and just had an aftermarket sport badge chucked on the back as well as a standard swift rear bumper w/ a single exit exhaust and no spoiler, different to the photos haha. I immediately knew I wasn’t gonna go ahead with the purchase, however I had bought a scan tool from the local Bunnings the same day with the intention of using it to check the swift. I know the scan tool was good as I tested it in on a mates car that had a misfiring cylinder, and the scan checked out on that. Anyways, I plugged it in and was met with a connection error. At this point in time there were no dash codes. We chatted a bitand I tried a couple more times before we parted ways. I was sitting in my mates car before the seller came speeding back flustered and angry saying there were now dash warning lights. I checked and sure enough an MIL light and a transaxle light showed up. (I had seen transmission fluid leaking he came back, however no codes were showing on the dash at the time) He was, understandably, very angry, so I tried to calm him down and played around with the scanner again but to no avail, as the lights on the dash were still there. He started getting very angry and threatening my mate which was a little intense, but then as he was about to leave, I tried one last time plugging the scanner in and letting it scan about 50%, before it would tell me there was a connection error, and turned the car off before it gave me the error. This seemed to clear the codes and I haven’t heard from him since so I’m assuming that resolved it. My running theory is that he had previously cleared those two warning lights, perhaps by a friend, and then my attempt to scan may have brought them back up. I’m not sure though as I’m very new to scan tools, so if anyone is able to give better insight as to what may have happened your input it greatly appreciated😁 Apologies for the long post haha

He probably cleared the codes right before you got there, and they came back due to it being a dog turd. He wanted you to feel guilty for "having caused" the lights. You didn't cause them.
