Much depends upon the type and make of the controller, which you don't mention in your posting.

All relevant data is normally provided in the datasheet that the manufacturer makes available either in printed format or on the internet; you should check that first. Furthermore, there have been numerous discussions on LCD initialisation codes on this forum, so if you do a search here you may just find what you need. What you are asking now is: my car won't start, can anybody tell me why? Answer: nope.
