I tried reading codes. Followed the intructions but nothing. Only plugging into port 6 got any response and that was the red led came on, turn mey to postion 2,hold button for 2 secs aaand.... nothing,. Red led just stays on and only port 6,could have been 5 tbh.
Diconnected battery and check light is gone.
OBD1 diagnostic box is a new issue. I'd like to be able to confirm or deny codes. New thread coming soon me thinks. But I think it is suffering from the same thing as my auxillary fan relay connector where the silicon used to fill the voids around the pins has disintergrated and no longer holds the connections in the place they should be. I think a trip to Jaycar for 4 pin plug is on the cards.
