code readers are cheap, scanners not so cheap. my auto xray is a scanner.
You can get software (scanner) for computers / smart phones now. Either usb or bluetooth connection from device to module that plugs into obd port.
last I researched pc based solutions, there were a few chipsets available and ELM was the best. That was a few years ago.
I have had my auto xray for many years, purchased it as a kit with all cables so I can even read some pre-obdii vehicles. I've even used it on some older ford and chrysler vehciles.
most tuners (possibly all) read obdii codes as well.
