Does anyone know/remember?

Startup fails on Focus Motor error.
The focus motor shows an invalid/out of range position.
How can one reset this value to zero in order to re-calibrate.
In other words, where is this value stored?
Is it on one of the cards in the E-Box?

Urgent expert advice needed!
TIA

Have you cleaned the lens cover? Not just wipe while in the machine, but remove the lens cover and thoroughly clean inside and out. A build up of dust can cause this error.
 
Thank you Magnus,
I followed your instructions but it had no effect on the focus position.
I shall now try to swap the Local boards, as suggested by Pach in a former discussion.
I shall report back later.
 
I replaced the Left Local Board twice with spare boards I have.
Each time the focus position showed a different value, all out of range.
These tests lead me to believe that the Focus Position values are stored on the Local boards.
How can I reset this value?

Update:
Plugging in our spare Focusing Motor Unit fixed the zeroing problem instantly.
So far so good, thanks for everyone's interest.
