The point of reviewing technical case closure is to make the documents, the physical vehicle, and the responsibility milestones correspond. Before reusing an earlier conclusion, check the repair result, the retest conditions, and customer feedback again, and re-approve if the source has changed. When archiving the closure, use this cross-border vehicle purchasing note to check the records on both sides. Confirm this batch's technical closure material before copying it into the next batch, so that an error does not spread.
