The required scan tool functions are described below:
- monitor, record, and playback of parameter identification (PIDs)
- freeze frame PID data
- diagnostic test modes; self-test, clear diagnostic trouble codes (DTCs)
- output test mode
- resetting keep alive memory (KAM)

- on-board system readiness (OBD monitor completion status)
Some of these functions are described. Refer to the scan tool manufacturer's instruction manual for specific information on scan tool setup and operation.
