Which fuse to pull to reset ECU

[FreeFlyFreak]

I read this somewhere but I cant find it in search so I thought I would post.

You can reset the ECU by diconnecting the battery, you can also reset it by pulling a fuse.....

Which fuse is it.


Thanks

Take the battery cable terminal off pump the brakes and put it back on. That's how you reset it.

I know that, I mentioned that in my first post.

But it can be done with a fuse too.

My question is which fuse.

10A fuse that's labeled engine b, it's in the fuse box just below the battery box under the hood. Right near the bottom left standing in front of the car IIRC

If you pop the neg cable off the battery just mash the brake, it'll drain what's in the system in a few seconds.

isnt there a 30a(labeled engine) that is near the top left corner standing infront of the car?

Yea that's the square fuse right? Not sure what all that controls, but the engine b resets the ECU.

Mazda runs the ECU from the fuse marked "ROOM". Check it out and you'll see.
