I think most of the codes are standard OBD 1 & 2 codes. So not sure if there model specific. Most are available on the net. But there's no way to find out the codes withough a reader. Halfords sell them for £20 or there abouts. But you can buy the cables and softwere for eBay that's a lot more capable for the same price.
What's up anyway? There been any symptoms to the mil light coming on?
there just seems to be a dip in power every now and then and wonderd if there was any way to find out ??? on my last Diesel Vaux Zaf b theres the break and accelerator pedel test that you could do to show up the codes. wonderd if there was some similar kind of test for the KIA ???
seen the Diagnostic usb kits on ebay, may invest in one at some point ??
