Hey everyone,
a couple of years ago I tried to jump my ecm port with a toggle switch, to do a torque converter lock up. I ended up disconnecting though after I found it put alot of strain on the trans. But since then I can't read the ecm from my scan tool. I can only pull the codes out thats it. Before I did that toggle switch thing I could scan the ecm. So could I have fried a connection somewhere or maybe something came loose.
