Re: Smartcraft
from the manual :
TRIM CKT HI/LO Power trim sensor circuit problem. Have
the system checked by your dealer.
To me this means that the circuit resistance is too low, indicating a short.
I would try replacing the trim sensor, ask a mechanic, they ALWAYS have some in their tool boxes as these engines come with the digital sensors (like you need with smartcraft) but are usually rigged with the analog sensor for an analogue gauge so into their toolbox they go!
PS, I would avoid the double posting, it is frowned upon.
