Default Canít read OBD2 codes but can Delete - 03-18-2019, 02:30 PM


I recently purchased a JB4 and the mobile setup which Iím using on an iOS device. Everything is working great, Iím very happy with the JB4 and the App.

The only strange thing is that I canít seem to read any OBD2 codes. I throw a CEL and the Ďdelete codesí function works. But when I can the codes it says ďfailed readĒ.

Iím reluctant to make any additional changes to the system like a firmware update, tuning and etc without checking in with you folks first.

Attached is a screen shot of the mobile app config.

Any suggestions???
