audios Posted January 18, 2006 Share Posted January 18, 2006 I have a vanagon with a subaru conversion ( obviously ) and it just started, not starting, it just cranks and cranks. How do i get the ECU to give me codes??? I see/have the wires out of the ecu but i dont know how to get the codes out. Quote Link to comment Share on other sites More sharing options...
ShawnW Posted January 19, 2006 Share Posted January 19, 2006 You must have a check engine light. Plug the 2 green connectors together and put the key to ON (not start) and watch for a morse code to flash on the check engine light LED. Each number has long short. The long flashes are the first digit, the short the 2nd. LONG LONG SHORT being 21. My bet is on 11 or 13 for a no start situation. I havent verified this code list but I think it is right: CODE PROBABLE CAUSE 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.

Legacy777 Posted January 20, 2006 Share Posted January 20, 2006 You need to use the black connectors. You can read the procedure on my site www.surrealmirage.com/subaru/engine.html Quote Link to comment Share on other sites More sharing options...
audios Posted January 20, 2006 Author Share Posted January 20, 2006 You need to use the black connectors. You can read the procedure on my site www.surrealmirage.com/subaru/engine.html i went there and did that the first time, the problem is i only have a couple of lights, batt, oil, oxs......there are other connectors under the seat near the ecu, could i tap into any wires to get the lead that goes to that check engine light in the normal subarus?? what color wire makes that light blink??

Legacy777 Posted January 20, 2006 Share Posted January 20, 2006 You can take a look at the following wiring diagrams & ECU I/O, but what you need to do is ground pin B56 12, and hook a light bulb in series with pin F47 19, and then ground the other side coming off the light bulb. Connecting pin B56 12 to ground will be like connecting the black read memory connectors. If you have any questions, just holler. http://www.surrealmirage.com/subaru/files/swap/2-7_ECU_I-O_page1.jpg http://www.surrealmirage.com/subaru/files/swap/2-7_ECU_I-O_page2.jpg http://www.surrealmirage.com/subaru/files/swap/2-7_ECU_I-O_page3.jpg http://www.surrealmirage.com/subaru/files/swap/6-3_engine_electrical1.jpg http://www.surrealmirage.com/subaru/files/swap/6-3_engine_electrical2.jpg Quote Link to comment Share on other sites More sharing options...
