I'm a Nissan master tech with electrical specialty, but shhhhhh.... don't tell anybody here who doesn't already know. Ooops, I just did.
The ZIFs Nissan used before '13 or so were generally the type with a separate lock bar, not an integral one. That's where the problem comes from, if the bar works loose then all those 0.5mm pitch connections aren't in the right places anymore. Usually just cleaning the stripes with alcohol and getting the connector properly re-locked is all you need.
