Paul Grainger Posted February 21, 2019 Share Posted February 21, 2019 It will do if it has an Efi engine. It is the old style star/led tester type. Should be on the n/s inner wing. Cheers Quote Link to comment Share on other sites More sharing options...
Cottyp Posted February 22, 2019 Author Share Posted February 22, 2019 Yes it's the 1.6 efi engine exactly where is it ?? And what does it look like cheers Quote Link to comment Share on other sites More sharing options...
Paul Grainger Posted February 22, 2019 Share Posted February 22, 2019 Hi, as you open the bonnet it will be hanging on the right hand side strut turret. There will be a bunch of three connectors. A black three pin, a black two pin for serial data and a blue two pin. Cheers Quote Link to comment Share on other sites More sharing options...
Cottyp Posted February 23, 2019 Author Share Posted February 23, 2019 Do I use the normal diagnostic gizmo I've got or do you need a different one I've got a picture of what you said to look for but it won't let me upload it on here Quote Link to comment Share on other sites More sharing options...
Paul Grainger Posted February 23, 2019 Share Posted February 23, 2019 Hi, depends on what gizmo you have got! The two pin serial link is for the FDS2000 diagnostic PDU which was really dealer only kit back then. The three pin plug is for the Star tester. Again dealer level but a lot more widely available. This is the early level stuff before the standardised 16 pin DCL connector for EOBD which came out around 1995. If you can find a Star tester then make sure it is a three digit one as you will need this one for the later EEC4 engine management module fitted to your car. Might be easier to ask at your local dealer if they still have a Star tester!!! If you do find one then code 111 is all systems pass Hope this helps.
