Verification system or verification method for detecting a connector position assurance (cpa) device's closure relative to a housing using a machine or electric/electronic scan system for reading or detecting surface scan of a predetermined word or character, and portions thereof

A verification method for detecting a connector position assurance (CPA) device’s closure relative to a housing, comprising the steps of:

• providing a connector position assurance (CPA) device having a partial portion of a predetermined word or character on a first visible or visual surface thereof;
• providing a housing having another portion of the predetermined word or character on a second visible or visual surface thereof, and
• scanning by a scan system at least one of said partial portion of said predetermined word or character on said first visible or visual surface of said CPA device and said another partial portion of said predetermined word or character on said second visible or visual surface of said housing, wherein said scanning step is comprised of a step of detecting whether said CPA device is in a pre-lock position or in a full-lock position relative to said housing based on whether said scan system detects whether said partial portion of said predetermined word or character on said first visible or visual surface of said CPA device and said another partial portion of said predetermined word or character on said second visible or visual surface of said housing are separated from each other or joined together.
