kiwisub Posted August 13, 2006 Share Posted August 13, 2006 hello all , while checking the diagnostic connectors under my dash (black and green ones ) why do the green ones when connected run the radiator fan in short bursts ? the black connectors told me the crank sensor was buggered so i replaced that at nz $ 160.00 , no more start issues now , can anyone explain the function of the green ones please , cheers blair Quote Link to comment Share on other sites More sharing options...

Setright Posted August 14, 2006 Share Posted August 14, 2006 It's also needed during a reset Quote Link to comment Share on other sites More sharing options...
OB99W Posted August 14, 2006 Share Posted August 14, 2006 http://www.surrealmirage.com/subaru/engine.html From the link given above: "NOTE: These instructions are only for the 90-94 Legacies with an OBD I computer. If you have a 95 or later Legacy, you will need a scan tool or will need to have the dealer read the codes." Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted August 15, 2006 Share Posted August 15, 2006 It's possible that the overseas models may have stayed OBD1, or at least retained the OBD1 connector functionality for longer then the US models. Quote Link to comment Share on other sites More sharing options...
OB99W Posted August 15, 2006 Share Posted August 15, 2006 :-\ It's beginning to look like the statement I quoted above is misleading; it should probably say that you can't retrieve the OBD-II codes without a scan tool. My own '99 Outback (obviously OBD-II) has the green connectors (although not the black ones). I haven't actually had a reason to connect them, so I can't verify precisely what that does. However, I found some info concerning the CEL D-Check codes during an online search (which I also haven't verified, but hopefully is correct); it's a bit more complete than other tables I've seen. If anyone knows which model years it applies to, please chime in. Here it is: For Later Models with Multi-Point Fuel Injection (MPFI) 11 Crank Angle Sensor or Circuit 12 Starter Switch or Circuit 13 Cam Position Sensor or Circuit (TDC Sensor on Justy) 14 Fuel Injector No. 1 (Legacy, Impreza, Justy, SVX) 14 Fuel Injector No. 1 and 2 (XT, Loyale, GL, DL) 15 Fuel Injector No. 2 (Legacy, Impreza, Justy, SVX) 15 Fuel Injector No. 3 and 4 (Loyale, GL, DL) 15 Fuel Injector No. 5 and 6 (XT-6) 16 Fuel Injector No. 3 (Legacy, Impreza, Justy, SVX) 16 Fuel Injector No. 3 and 4 (XT) 17 Fuel Injector No. 4 (Legacy, Impreza, SVX) 17 Fuel injector No. 1 and 2 (XT-6) 18 Fuel Injector No. 5 (SVX) 19 Fuel Injector No. 6 (SVX) 21 Coolant Temperature Sensor or Circuit 22 Knock Sensor or Circuit (Right Side on SVX) 23 Air Flow Meter or Circuit (Exc.
