I think the BAR97 machines have a lockout mode on them that if they don’t communicate with the state’s servers or if the amount of smog certificates are expended, the machine locks out. CA recently mandated all smog machines use broadband internet to communicate with the state instead of dial-up(yes, the smog machines used a USB 56K modem to dial into the state).
The older BAR84 machines(I think Allen or Bear/SPX made them, they ran DOS on a 286) don’t lock out and do the TSI mode inspection.
CA went BAR-OIS with any PC running Windows 10 with a ESP or Bosch/Delphi OBD interface. They needed to “smog” hybrids but you can’t run them on a dyno(the Honda ones, yes but not a Toyota or Ford hybrid). Toyota warns the inspection mode on a Prius and its ilk is intended for smog inspection but never to drive the car in that mode.
