Quick answer: It may help isolate a mechanism issue, but final qualification needs the specified cable, connectors and routing.

Can a dummy cord replace the production cable during qualification?
A dummy line can have different friction, stiffness and winding behavior. Results from it should be labeled as a diagnostic test. Record the production cable revision and its handling state so repeated trials are comparable.

A practical verification method
Repeat the final acceptance sequence with the actual cable system and retain its part identification in the report.
| Item | What to record | Purpose |
|---|---|---|
| Reference configuration | Part or assembly identity and drawing revision | Make comparisons traceable |
| Test conditions | Relevant position, direction and operating condition | Compare the same characteristic |
| Decision evidence | Repeat the final acceptance sequence with the actual cable system and retain its part identification in the report. | Resolve the specific question before approval |

Use the result in an engineering request
Describe the observed condition and the required function separately. Include the relevant drawing revision and your results from the check above. If an acceptance limit has not been established, identify it as an open design input rather than treating a successful trial as approval.
