Default I am perplex about the ecu reset

My check engine light came on in my 2001 rs. So I was searching on the board and found 2 ways to do it. I like the hole idea of find the green and black plugs and putting them together. I found the green plug easy. But the black plug I could only find 1. So I started to look around and in that same harness there are two black wires with connectors on the ends taped together touching. So what is that is that my plug I am looking for? Is the plug gone?

Just take the negative lead off your battery for 30 minutes, start the car up and let it come up to temp, then shut it off.

You really shouldn't just clear the CEL without getting the code read first. You'll have no idea what the problem was in the first place.

Cool

Actually, Shiv from Vishnu showed me an easier way to do it. Just take off your negative battery cable and step on the brakes. Instant reset!

Hello,

I showed that trick to Shiv Basically, once you remove the negative terminal, you want to remove any residual current - like any capacitance in the ecu. Hitting the brake lights up the tail lights and drains the remaining capacitance. Voila, ecu is out of power and is reset. That works on MOST car brands.

Thumbs up I love this board!

.......and I was just about to do a big search to find out how to reset my cel! This sounds like it would work on my wrx, or atleast it should.

Has anyone reset their ecu by taking the neg off and pressing the brakes?
