northwestguy1 Posted February 18, 2015 Share Posted February 18, 2015 (edited) Hey everyone, I noticed a power light on my dashboard flashes 16 times when I start up my car what does this mean?? Thanks! Ben Edited February 18, 2015 by northwestguy1 Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted February 22, 2015 Share Posted February 22, 2015 The 16 flashes of the power light on start up indicates there is an active code in the TCU. Use these instructions to pull the codes. http://www.surrealmirage.com/subaru/trans.html I am also going to move your thread to the new gen forum.

northwestguy1 Posted February 24, 2015 Author Share Posted February 24, 2015 (edited) So I did the procedure that you described and I get 2 flashes. How do I interpret this code to match the code table? Also I have a rough idle going on when the engine warms up. I cleaned my MAF sensor which helped a little but the idle is still rough. Should I check anything else? Thanks, Ben Edited February 24, 2015 by northwestguy1 Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted February 24, 2015 Share Posted February 24, 2015 Ben,The power light will flash in the same manner that this video of the check engine light does, long flashes are the tens place and short flashes are the ones place. Do the flashes you saw correspond to a long flash and a short flash or did it do something else?You can also try checking the ECU for any stored codes.http://www.surrealmirage.com/subaru/engine.html Quote Link to comment Share on other sites More sharing options...
northwestguy1 Posted February 24, 2015 Author Share Posted February 24, 2015 (edited) Yes there was a long flash and two short flashes. Edited February 24, 2015 by northwestguy1 Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted February 24, 2015 Share Posted February 24, 2015 Yes, so code 12 and that would be duty solenoid B. You can try using the diagnostic pages below to test wiring and solenoid. http://main.experiencetherave.com/subaru_manual_scans/FSM_Scans/duty_solenoid_b_diag1.jpg http://main.experiencetherave.com/subaru_manual_scans/FSM_Scans/duty_solenoid_b_diag2.jpg I'd suggest clearing the TCU's memory and see if that same code comes back. Pull the EGI/TCM fuse (fuse 14) for about an hour, reinsert, drive the car, and see if the same code comes back. Quote Link to comment Share on other sites More sharing options...
northwestguy1 Posted February 24, 2015 Author Share Posted February 24, 2015 (edited) Thanks for the information I will try that procedure. Edited February 24, 2015 by northwestguy1 Quote Link to comment Share on other sites More sharing options...
ChestoLegacy Posted February 25, 2015 Share Posted February 25, 2015 I had the same issue where the power light flashed 16 times and the problem happened to be the Duty c solenoid and ultimately torque bind. i didnt want to take any chances of having it repaired and i just bought another transmission. cost was about the same though Quote Link to comment Share on other sites More sharing options...
