Hi I haven’t done anything to it but now wen I put the wire in the obd connecter the check engine light just stops on no flashing
Thanks
It should blink. Go through ALL grounds. Remove each one, clean the contact areas and then reinstall.
Here is info on how to obtain the codes correctly using a paperclip: Diagnostic codes OBD I
