I have now sprayed the pins and OBD connector with contact cleaner,still no go. So,this is where im at. The code reader that worked before,is now saying linking error. The Multiecuscan connects to all the other systems,eg service,airbag body computer etc but not the engine system. I also have my ecu blanked and use a Fixitsan dongle to cancel the engine management light,which has worked up until now. This obviously connects to the engine management side of the OBD socket. It has now stopped working and light is coming on.
From this,it seems that the OBD socket must be where te fault is.
I looked into buying a OBD tester but dont really want to spend out on a piece of equipment i will probably never use again.
Can anybody tell me if i can check the OBD socket any other way?
