I think one way to know is to access the AWD module and monitor the ATC PID (paramiter identification) and see if it is a On/Off display or a percentage and do a pull and see what it reads. I do not think you can monitor the wheel speed sensors from this module so you will half to listen to the front tires for spin and seat of your pants feel when launching. Then command the ATC PID to 100% and repeat to see what happens or goes snap/crackle or pop LOL. The only way I see how this can be done is with Ford IDS software. I just started this topic to see if anyone was thinking the same thing I was. Fodd for thought
