I was on my way home from work today when I got a hard limp mode, cel, and the car wouldn't go. I put the emergency lights on, pull over and restart the car. It's still idling funny, so I let it sit 30 seconds to clear the limp mode. During that time, I try to read my codes with the scanner. The scanner is unable to communicate with the ecu. I get the car to go and make it home to try the laptop to see what's going on. Evoscan cannot communicate with the ecu either. So now I'm like wtf!? What do I do?

I've reset the ecu, and still nothing.

 

Describe how you got the CEL, were you under boost, if so, how high? Can you connect with ecuflash or mitsulogger to see if any other program can connect?

You said you reset the ECU - did you do it by unplugging the negative battery terminal and leaving it off for at least 10 minutes?

Yes, unplugged the ecu for 30 mins.
Checked fuse 5 under the dash.
Nothing will communicate with the ecu. Ecuflash included. 3 methods, none work.
I was doing 30 around a curve and then it hit hard limp mode.
