You'd have to trace out how the motor is switched on - is it this mosfet or a N-ch somewhere else. If it shorted I would think the motor will stay on.
Otherwise this is a motor back EMF diode. It's not a (reversible) motor needing a 4-mosfet H-bridge?

Is the other device marked as D? if it is how does it check, does it check like a dual diode, or like a transistor?
Where is it in the circuit?
is it across the motor?
Post a clear picture of the whole area of the board
I think D5 is the large part under the Q18 silkscreen and might not apply. You can a current-sense resistor R155 as well.
Usually you'd see a N-ch. mosfet turning a motor on and off. If it's reversible, then a P-ch up top on the H-bridge.
The only part that doesn't fit is OP finds the part shorted yet the motor will not run. If true then there is another problem, or it's the gate shorted.
