See my comments re this on your duplicate posts. This error can be a corrupt file and a uninstall followed by a reinstall might be the go.

By the way when you post here are you using a mobile rather than a PC. I notice there is no body on yours and other posts as well as mine when a mobile is used.
Here's a good OBD app that does real time cars scanning https://play.google.com/store/apps/details?id=com.motordata.obd, I use it all the time. And it's free on Google play.
