When the battery is disconnected everything clears including Emissions readiness flags. The SAI has to run at least once to set its "Ready" flag, that's how "they" block people from disconnecting the battery right before going to the emissions check.

Clearing the Readiness codes with a code reader or Durametric also does not work - they remain Pending and are detected when connected to the SMog Test machine=automatic Fail !
