For confirming that car diagnostic software works overseas, start by locking down the compatible models and hardware interface first, then cross-verify the account, region and license term and the updates, technical support and data permissions. Have the China team log in once with the target account, then test the diagnostic hardware, model coverage and software updates; region locking should be caught before shipment.
See the companion steps in What service training do dealers need before selling Chinese PHEV and EREV models?. The supply and warranty responsibility for car diagnostic software overseas must be written into the contract or service agreement; a supplier's verbal assurances are no substitute for a long-term commitment. If you need the models and export documents behind car diagnostic software overseas re-checked, submit the checklist to Starvia Automotive for a further review by the China team.
