TCU Codes

[mjm4jc]

Hello everyone,

So I've been trying to pull transmission codes on my 95 LX Wagon 2.2L using the handshake method. Unfortunately, it is not working. I read on some other forums that after going through the process, the last thing to do before the light flashes the code is to depress the gas pedal. I also read that some people are putting a ground pin in one of the connectors first, and then going through the process. I'm assuming that my Subie has the phase 1 4EAT trans? If so, can someone explain the correct/complete procedure? I did the handshake method on my daughter's 97 Impreza many years ago and don't recall ever having to depress the gas pedal or ground out any pins on any connector. But that was long time ago, and my memory isn't always that sharp. Please advise.
Thanks in advance,
Mike
