Failed Hybrid health check

[Itsfine]

My 2014 Yaris hybrid has just failed the annual health check. I have been told to take the car back after 320 miles for a re-check. Are you supposed to get an explanation of a failure and what is the significance of 320 miles?

Has the car been sat for a period of time ?

The HHC does give a basic reason, e.g Fault code stored, 12v Battery weak, Battery recently disconnected, DTC recently cleared, the mileage is required to ensure none of the previous has recurred before providing HHC cover. If you PM your chassis I can look and see what reason was stored for the failure.

Hi I had to wait 500 miles to retest my prius after failing the Hybrid health test 4 times only to find it was a faulty lead on the tester that was at fault I had to contact the Toyota Portal  to remove the 4 extra entry's automatically put in my records by the dealer

If it fails should the fault not be covered by the extended hybrid warranty?

Car has not been sat but has only been on short runs during covid.  I have warranty.  The dealer disconnected the Battery to reset the display so could this have caused the fail?
