Interesting- I do not think we have seen that one before. It is service code (error number) 68 and the explanation is somewhat generic- there is some contact difficulty with the ignition switch housing KiPass unit. ?? It has absolutely nothing to do with the steering lock as we think of it (where you turn the bars fully to the left and turn the key fully counter clockwise) but the electronics locking aspects of the ignition switch.
Seeing as you opened the gray connector, make absolutely sure it is fully seated and connected. Sometimes it take a bit of force to fully close that connector as there are seals inside it that make it waterproof.
If it goes away and stays away, I would ignore it and chalk it up to an oddity of the system resetting after being disconnected from the main battery.
