VCM Code A4 - Overide 3 key turn

Hi Quick Question!
I'm receiving a Code A4, I was told my VCM is bad and will cost in the neighborhood of $3k to replace, mind you I had it replace 2.5 years ago. Lift truck will not move, error code message reads "contact service personnel". I flicked the key switch 3 times to the right On position, and everything worked just fine, and error message is no longer visible in this mode but 3 error icons are lit. When I turn off and 1 key turn - ON again, error code A4 appears and Vice a Versa.

Is the 3 key turn a Service Tech override?
