Course must be if you steer wrongly (5)

I believe the answer is:

reset

I'm a little stuck... Click here to teach me more about this clue!

'course must be if you' is the definition.
I can't judge whether this defines the answer.

'steer wrongly' is the wordplay.
'wrongly' indicates an anagram.
'steer' with letters rearranged gives 'RESET'.

Can you help me to learn more?

(Other definitions for reset that I've seen before include "adjusted" , "Return to original configuration" , "Restore to required state" , "Adjust (eg clock, tuning)" , "Trees (anag)" .)

I've seen this clue in The Globe and Mail and The Irish News.
