Hi there,

Thank you for the donation,

Some OBD11 connectors only have 5 or 6 wires this is not important, what you will have to do is get a scan done and report the codes her for more assistance, start here,

I don't know what you have access to there, I use a Snap on scanner, this is a professional unit and it is very expensive, you may be better of contacting a dealer and getting them to do it, as many of the cheaper generic scanners are not that good and don't pick up all codes.
