at this time, after changing the f&R switch, does the hour meter ever show the hours after it starts, or does it just show this error? did it make any change at all?
f16 indicates both directions are sending the same signal to the computer for over 2 seconds..
did someone install a back up alarm?
you may be going to check 'pin to pin' from the directional switch to the ECM.
