i have bought a canobd2 3030 . i have had 2 codes wich are cleared now. the codes were po325 and p0306. this is a 97 villager ls. when i retry the reader it reads that the first three items are ok and goes onto the following to check but with no results. just bleanking and yellow led with ?. the problems i am having right now is there are no more codes and the scanner wont go beyond the catalyst monitor,oxygen sensor monitor,oxygen heater monitor and egr monitor. those settings just keep blinking. would there be a fuse or maybe relay that may not be working.? i still have no gas guage either.
