i have a 2006 freestyle , the cel. light is on and the wrench. but its not giving me a code when scanned. the cruise quit working and theres a ticking coming from under the dash on drivers side. i put a new throttle body on . no change .could this be a bad ecu or something. the car goes into limp mode after about 5 minutes of being started.car runs and idles fine

For $125, it might be the CP9180 which does do a certain amount of testing, it can clue you in if the ECU is even responding. The clicking may be a relay with either an intermittent signal, loose connection, or failing coil.
