O.K. ECU fuse pulled, engine light on, going off when??
OK, i pulled the 15amp fuse for the ECU in the interior fuse box...I knew ahead of time that the engine light would go on....when or how does it go off, if ever.....
u most likely have to reset everything cause ive never seen the light go out after a while
just take the negative off the battery for 10 15 minutes if it stays on after that u have a problem or just more christmas lights

Another myth about the ecu reset...will the madness ever stop???
Dude..that is NOT how to reset the ecu. Read-up on how to do it in the Helms Service Manual, or do a search..i'm sure someone has posted on this before.

Dude...yes that is the way to reset it...specifically said that in the Helm's manual...also said that the engine light would come on, which it did, i pulled the fuse labelled ecu, started car, turned off car, replaced fuse, turned on car, effectively RESETING THE ECU, not a myth, it worked, I just wanted to know if the engine light would ever go off.

Allright..i'm here to learn, so here's my source:
Quote:
Helm Service Manual (97-99), Section 11-37, ECM Reset Procedure: Turn the ingnition switch OFF. Remove the CLOCK RADIO(7.5A) fuse from the under-hood fuse/relay box for 10 seconds.
Where's yours..page number or whatever so i could look it up.
try ntpog.org, they have a huge deal about it. What i know from experience is that pulling the 7.5 amp clock/radio fuse did nothing except make me reprogram the stereo, the 15 amp in the interior box, did make a difference and the engine light came on as was said that it would happen, pull both if you want,
There was someone a while back who posted instructions on a permanent switch that resets the ECU by flipping the power to it off and on with a switch. He said it took care of the ENGINE light so... check it out...It might be at that NTPOG site... I want to do that but I haven't the chance to research what kind of switch I need and what ratings for voltage etc etc. And does anything if you can drive with the ECU OFF?

That was me, I wrote the article. The correct fuse is as Kool-Lude stated, the 7.5A under the hood. I am not sure of what that ECU fuse is in the cabin, though I suspect it's one of the power buses. Regardless, it's NOT the proper way to reset the ECU and I did not indicate that it was in my article.
The switch goes inline with the line to the ECU from that fuse. It's like pulling the fuse, but you don't have to lose backup power to the radio (and have to redo the code, presets, etc.).

Cool there you are... I've been meaning to ask you... can you use any kind of switch from radio shack? I saw a SPST Automotive switch but I wasn't sure which kind is which. And when you say its not the proper way to reset the ECU are you talking about the switch or pulling the fuse? Thanks for the idea though, good idea.

SPST is what you need. There are many differen kinds of switches, SPST is all you "need." You can us a SPDT and not use one "position" or get a DPST or DPDT and not use one circuit or setting. SPST is one circuit and two positions (on or off) and that's all you need.

I was referring to the ECU fuse this thread is about. I'm not sure specifically what circuit it is, but it is NOT backup power. It is not the right way to reset the ECU. The switch isn't technically the "right" way, either, at least as Honda designed it. Electrically, though, it does the same thing.
humm...looks like you pulled the wrong fuse. 7.5A under the hood is the way to do it.

Phuck it all, I pulled both to gaurantee it worked...the 7.5 amp clock/radio fuse makes no sense to me...what makes sense is the actual ecu fuse..oh well, the car only responded to the ecu fuse with the engine light, nothing happened with the 7.5amp clock/radio fuse except I had to enter the radio code yet again.
