Car is a 2003 evo viii

I tried seaching though the fourms but couldnt come up with anything. The problem i am having is that there is the cel is on and i tried to scan it and it keeps coming up with car not connected.etc and yes the key .

Anybody have this problem

 

What are you trying to scan it with? A standard OBDII scanner or a laptop program (Evoscan, Scan Tech)

Could be a ECU, the port, or a scanner issue

 

i tried a coulpe diff scanners. im gonna try my friends snapon solist today.

 

I believe the OBD-2 port gets its power from the dome light. It might be a power/ground issue with the port itself. I would start there.

 

Check your fuses also.

 

if your using a laptop scanner (evo scan) make sure the com port setting is the one you are using, i had that problem and that was my fix, just had the usb cable plugged into the wrong com port
