Ok I will check those connections out.have ypu had problems with some of these in your area? To be honest this is the only customer we have that has hyundai's.I just got the correct pass word for the software today. Gonna troubleshoot this unit after we get a new diaphragm for the mixer.it back fired so hard last Friday that it blew a hole in it.i have also been told to watch out for a stick g valve but I'm sure that it would back fire while the unit is in motion if that we the case. Also have been told to Inspect the negative wires in the control harness.
