The motor control system failure is one of those infuriating warnings that could represent a multitude of issues or nothing at all.
When the MCSF first appeared on my '54 GT it was followed intermitantly by immobiliser failure warnings and miscellaneous other warnings that I have forgotten.
If you do a search for "motor control system failure" on the forum, you will find loads of information to determine whether or not yours is serious or not.
The solution in my case was to change the battery, which was the original and 4 years old. This cleared the spurious MCSF messages as the GT computer needs clean voltage to operate correctly.
