- `Mode`

  - **0** - Disable this function.

  - **1** - Enable this function.

- `Time to Stationary`

  If it is detected that the vehicle is stationary with ignition on for the period of time specified by this parameter, it is considered to be in idling status.

- `Time to Movement`

  If the vehicle moves again is detected and the status is maintained for the period of time specified by this parameter, the vehicle is considered to exit idling status.

- `Time to Ignition Off`

  If the vehicle ignition off is detected and the status is maintained for the period of time specified by this parameter, the vehicle is considered to leave idling status. 0 means that as long as the vehicle ignition off is detected, the vehicle is considered to exit idling status.
