stevie_b Posted August 4, 2005 Share Posted August 4, 2005 Unusual request possibly, but I want to trigger an ECU error code. Any one will do, but the easier to generate the better. I'll disregard any suggestions like "remove engine"! I've fitted a Pete Betts DSC unit and currently have the dashboard off. I'd rather not unsolder the DSC joints (to trigger code 42) because my soldering is not good, and I've (eventually) got joints that are strong! The reason, if anyone's interested: I think my red triangle warning light in the rev counter dial doesn't work when the engine management warning light (orange engine icon, RHS of dashboard) comes on. The bulb is fine, because the red triangle never fails to illuminate when I apply the handbrake. When I had error code 42, the orange light would come on and stay on, but the red triangle (after a couple of weeks of having the error) didn't. It flickers on when I drive over "rumble strips" in the road. TIA Quote Link to comment Share on other sites More sharing options...
Ian C Posted August 4, 2005 Share Posted August 4, 2005 The flickering may be brake fluid related The warning light doesn't always come on, it depends on the problem. Try unplugging the MAP sensor while it's idling. -Ian Quote Link to comment Share on other sites More sharing options...
stevie_b Posted August 4, 2005 Author Share Posted August 4, 2005 Thanks Ian. Do you know if the red warning triangle is supposed to come for a "code 42 - no.1 speed sensor" error? I suspect it is: it used to when I first had this problem, but after a few weeks, it just suddenly didn't come on anymore even when the orange engine light did. I'll try the MAP sensor thing anyway though! Steve Quote Link to comment Share on other sites More sharing options...
Ian C Posted August 4, 2005 Share Posted August 4, 2005 Yeah, it does. I was gonna suggest that one as I knew it was a definite, but the speed sensor is on top of the gearbox Tricky to unplug compared to the MAP sensor! -Ian Quote Link to comment Share on other sites More sharing options...
carl0s Posted August 4, 2005 Share Posted August 4, 2005 Would triggering the SRS airbag light give you an error code? Disconnect the ODO with the ignition on. Quote Link to comment Share on other sites More sharing options...
stevie_b Posted August 5, 2005 Author Share Posted August 5, 2005 Ian: I should have pointed out earlier that I have an NA. Am I right in thinking that I don't have a MAP sensor? (I only found this out last night!) Carlos: my supra doesn't have airbags, so this may not work. Thanks for the suggestions guys, I do appreciate it!

Ian C Posted August 5, 2005 Share Posted August 5, 2005 Ah, that changes the rules a bit. But you do have a MAP sensor and it's mounted on the bulkhead just behind the intake manifold. You'll find a vac hose going to it if that helps, sorry no piccies. -Ian Quote Link to comment Share on other sites More sharing options...
