Hello. If I remove the CEM for inspection and disconnect the wiring harnesses will I have to have the CEM reprogrammed?
Thanks.

There is not correct question.
If you install back your original CEM after inspection, NO, not need program something.
If you going to replace CEM to another CEM, YES, you should reprogram replacement CEM.
