Default another problem~

So, I want to reset the ECU~ I know all the steps, but the problem is, how do you disconnect the negative terminal? Do I just unscrew the nut, and put the thing off or what?

Someone please help me~~

Thanks in advance!

Angel

Correct, undo the nut then pull off the connection from the terminal. Be sure it is not touching the post and step on the brake pedal for a few seconds to totally drain the power and that's it!

If you've got an alarm, have the key-fob ready to disarm the alarm when you put the negative terminal back on.

Better alarms will trigger - especially if you've got a battery backup siren.

My cheap alarm (that I overpaid for) doesn't have this feature.

mine is the subaru alarm, so will it trigger? Do you know where is the alarm located under the hood? Cause I was reading the intake install instructions from Cobb, and it said if I remove a "thing" (I forgot the name) at the driver side, then it will affect the alarm. And I don't want to kill the alarm~ any idea?

I don't know if it will trigger or not. Only way to find out is to do it!

Just have the key-fob near by so you can turn it off if it does go off.

Yeah, that's about right.

Just disarm the alarm before doing anything (i.e., unlock the doors) and you'll be fine.

As for the bolt, spray some Liquid Wrench or WD-40 into the threads, let sit for 10 minutes, then try to take it off with an impact wrench. You can borrow mine if you want.

Isn't WD-40 flammable? The bolt is under the hood, like around the engine~ is it okay to spray there?

Yes, it's flammable, but you're not spraying flamethrower-style all over the engine. Connect the little straw to the spray can and aim at the base of the nut, below the flange.

Also, if the bolt is rusted you should probably wipe off the WD-40 after it's off, and put some anti-seize compound on the threads before putting it back in.

Dunno what could be causing that on an '03RS ... but on my car, there's one airbox bolt just underneath the hood scoop drain that gets a lot of water and is a rusty mess (as some of the other guys can attest)...

Anyway, if you wanna meet up I can probably help you out... impact wrench is the best chance to get that bolt out without stripping the threads.

I know the answer.. "Turn it counter-clockwise."

Hehehe .. *duck*

Seriously these guys are right. An impact wrench and liquid wrench are the best you can get.. If you strip the head you can drill it out and re-tap/thread the hole. Or try an easy-out device that works as often as not.

Oh and I've always had good success overcoming strength issues by using a 'persuader' bar or box ended wrench. I just hook one on to the end of a wrench I'm working with and it gives me extra leverage. As always your mileage may very and the risk you take is your own. Etc..

Thanks so much for offering help!! But I don't have an impact wrench nor a liquid wrench~

Ah, now I see. The bolt is tight because the ABS solenoid vibrates around and puts stress on that point.

Anyway, I sent you a PM. You can borrow my dinky 12V impact wrench and hopefully finish the job.

Oh, that bolt! You'll need to give a little blood to the seized-bolt gods to break that thing free!

Yah, I remember getting that bolt off. She was a tough nut to crack. It's tight for a reason - you do NOT want that thing comming off, lest you lose all brakes!

"The Persuader" is any heavy hunk of pipe or wrench you can attach to the end of your ratchet or whatever to get some extra leverage.. You want to make the handle longer.

Only do that if you cannot get an impact wrench.. You don't want to make more of a problem if the bolt is siezed..
