Jamie698 Posted April 2, 2014 Share Posted April 2, 2014 Stumped, alternator went and lit up my dash like a Christmas tree, installed another and it's seems to be charging fine getting 14.4v under idle and no flat battery yet so all good. However, I have the warning light indicator still illuminated red triangle one, have reset the ecu a couple of times, can't get a code out of the ecu via bridging with paper clip. Don't think it works on early supras just flashes the over drive light on key turn 2 like some other members have reported. Brake fluid fine and all doors closed, handbrake down too Should I have a fuse in ecu b slot in footwell, tried chucking one in and illuminates the headlights low beam iirc even with lights off? Final symptom is that the traction control button has no effect, trc off does not illuminate? Thoughts appreciated. Quote Link to comment Share on other sites More sharing options...
Guest Budz86 Posted April 2, 2014 Share Posted April 2, 2014 Have you checked all the other fuses in both boxes? Might have been a surge and caused a one to blow Quote Link to comment Share on other sites More sharing options...
Jamie698 Posted April 2, 2014 Author Share Posted April 2, 2014 Yeah checked both boxes, all look good. Quote Link to comment Share on other sites More sharing options...
Tommyd16 Posted April 2, 2014 Share Posted April 2, 2014 Do you have an active spoiler? I had to unplug the active spoiler ecu to clear the triangle. Also try bridging with a decent bit of wire when checking for codes. I used a paper clip and got nothing but a code with wire. And drive around for 15 mins or so before checking and don't reset ecu before you do as you will wipe codes. Probly already know this but just thought I would make sure lol Quote Link to comment Share on other sites More sharing options...
Jamie698 Posted April 2, 2014 Author Share Posted April 2, 2014 Tried speaker wire to try and get codes but no joy. Active spoiler is fine. So it's got to be this ecu-b circuit, abs, traction control are both on this fuse. When a put a new fuse in it doesn't blow but illuminates the headlights, I can't think what's blown to cross the two to put power to the headlights. Maybe time for an auto electrician Quote Link to comment Share on other sites More sharing options...
ghostbuster Posted April 3, 2014 Share Posted April 3, 2014 It may sound silly but make sure your brake fluid is topped right up:idea:, honest this really has caught out a few! Quote Link to comment Share on other sites More sharing options...
Jamie698 Posted April 3, 2014 Author Share Posted April 3, 2014 Yeah Brake fluid is on the max line, tried disconnecting the fluid sensor as well, didn't change anything. ECU-B circuit im 99% sure now is the problem, just scratching my arse to where to start troubleshooting the circuit. I'll hopefully have time to tinker tonight.
