Conditions:
- engine temperature >= XX °C (XX - Measured values group XXX field X)
- catalyst temperature > XXX °C (XX - Measured values group XXX field X)
- parking brake = ON
- gear engaged (P) (automatic transmission)
- on-board voltage > XX V (XX - Measured values group XXX field X)
- appliances = OFF

Note:
- The Readiness Code must be created as the last diagnostics task. Later deletion of the memory could also result in deletion of the created Readiness Code.
