Bent, missing or corroded pins should be declared before a module is sent for assessment. Connector damage can affect both the original vehicle fault and the ability to test the unit safely. Do not attempt to straighten every pin before the specialist has seen its condition.
Photograph and protect the condition
Take clear external photographs without touching exposed terminals. Record whether damage was present before removal or occurred during handling. Ask the recipient how the connector should be protected for transport and whether the vehicle-side connector also needs inspection.
Do not pack a unit loose among heavy parts or allow conductive debris into the connector. Keep the module label visible and include the agreed job reference. The assessment should distinguish connector restoration from internal electronic work and explain what can be verified afterwards. If the mating harness is damaged too, coordinate that repair before refitting; otherwise a repaired unit may return to the same unresolved connection problem.
